Introduction
ALMATEC air-operated diaphragm pumps are constructed according to the state of the art and they are
reliable. Imminent danger by operating error or misuse can lead to damages of properties and/or persons. The
pumps are to be applied for the intended use and in a safety-related proper condition only.
Each person working on the ALMATEC air-operated diaphragm pumps concerning installation, start-up,
handling or maintenance has to read this manual completely and in an attentive way and has to follow all
mentioned procedures and safety notes.
General description of the machine, appropriate use and residual dangers
The ALMATEC E-Series pumps are oscillating positive displacement pumps and
are based on the functional principle of double diaphragm pumps. The basic
configuration consists of two external side housings with a center housing
between them. Each of the side housings contains a product chamber which is
sealed against the center housing by a diaphragm. The two diaphragms are
interconnected by a piston rod. Directed by an air control system, the diaphragms
are alternately loaded with compressed air so that they move back and forth. In
the first figure, the compressed air has forced the left-hand diaphragm towards
the product chamber and displaced the liquid from that chamber through the open
valve at the top to the discharge port. Liquid is simultaneously drawn in by the
right-hand diaphragm, thus refilling the second product chamber. When the end of
the stroke is reached, it reverses automatically and the cycle is repeated in the
opposite direction. In the second figure, liquid is drawn in by the left-hand
diaphragm and displaced by the right-hand diaphragm.
The appropriate use of an Almatec air-operated diaphragm pump of the E-Series refers to the liquid transport
taking into account the operation parameter mentioned in this manual and in compliance of the given terms for
commissioning, operation, assembly, disassembly and maintenance.
Even if all necessary safety measures described in this manual have been met, a residual danger exists by
leakages or mechanical damages. At sealing areas or connections liquid can be released uncontrollably then.
Storage
In general the ALMATEC pump is delivered operational and packaged. If the unit is not installed right away,
proper storage conditions are important for a trouble free operation later. The pump has to be protected from
wetness, coldness, dirtying, UV-radiation and mechanical influences. The following storage conditions are
recommended:
- Steady ventilated, dust and vibration free storage room
- Ambient temperature between 15°C and 25°C with a relative humidity below 65%
- Prevention of direct thermal influences (sun, heating)
Codesystem
The ALMATEC Maschinenbau GmbH is certified as a modern, quality-orientated enterprise according to
DIN EN ISO 9001:2008 and 14001:2005. Before release for dispatch, any pump of the E-Series has to
undergo an extended final control. The performance data registered during this are archived in our records and
can be read back at any time.
As a general rule in the countries of the EU only such machines are allowed to take into operation, which are
determined to meet the regulations of the EU machinery directive, the harmonized standards, European
standards and the respective national standards. Hence the operator has to verify whether the ALMATEC
pump manufactured and delivered properly according to the customers order meets the mentioned
requirements.
Therefore make sure, before putting the pump into operation, that the pump and the used materials of
construction are suitable for the provided application and the installation site. To check this, the exact pump
code is required. This code, the serial number and the year of construction are noted on the identification
plates on the pump itself.

Operation in explosion-proof areas and for inflammable liquids (Reg.-No. PTB: 03 ATEX D004)
For inflammable liquids as well as for applications in explosion-proof areas, only pumps
with housings and fittings in conductive plastic materials may be used. Pneumatic
diaphragm pumps of the E-Series with the housing codes F (PE conductive) and U (PTFE
conductive) meet this requirement. The pump has to be grounded. A connection to ground
the pump is included in the center housing [4]. All other housing parts are connected to
the center housing; therefore it is not necessary to ground single parts.
ALMATEC E-Series pumps made of electrically conductive PE/PTFE are suitable to be
used in explosion areas of the category 2 and 3, atmosphere G/D, which are liable to the
94/9/EG. Conductive diaphragms (liquid side) are applicable without restrictions for
transferring liquids of any explosion-group.
When using non-conductive diaphragm materials, the following exemplary protection measures have to be
respected:
- The pump is always used for the transfer of exclusively fluids which are conductive or soluble in water or
- Dry-running is avoided by action steps within the facility and/or its control or
- The system is inertisated in case of dry running by nitrogen, water, carbon dioxide etc. when the fluid transfer
ends.
Piping systems and product connections have to be grounded separately. To avoid ignition hazards the
formation of dust deposits on the pumps must be prevented. In explosion proof areas repair working only after
careful inspection of the practicability and only with appropriate tools. For the ATEX marking according to
94/9/EG please see the attached conformity declaration and the according pump label.

Recommended installation
Product ports
The product ports are integrated into the center housing [4]. Different port configurations can be obtained
(without using of a screwed pulsation damper only). The standard configuration of the E-Series at delivery is
with the suction inlet horizontally at the bottom and the discharge outlet horizontally at the top (figure 8.1).
Further possible configurations:
 Suction inlet vertically at the bottom, the discharge outlet horizontally at the top (figure 8.2)
To obtain this configuration, the plug of the center housing [13] has to be removed and set in the
standard inlet.
 Suction inlet horizontally at the bottom, the discharge outlet vertically at the top (figure 8.3)
Unscrew the housing bolts [19], take off the side housings [1] and turn the center housing [4]. Remount
the pump and adjust the plug [13] accordingly.
fig. 8.1
fig. 8.2
fig. 8.3
Installation, operation and maintenance
UV-radiation can damage the housing parts of pumps made of PE (material code E). In general, the pump has
to be connected load free. Neglecting this causes leakage and maybe even damages. To avoid vibrations,
pulsation dampers and compensators are recommended. Before connecting the pump, take the yellow blind
plugs out of the suction and discharge connections as well as the air inlet [23] in the center housing [4]. The
connections of ALMATEC air-operated diaphragm pumps made of plastic have slightly tapered threads. Use
threadseal only sparingly, otherwise the connections could be damaged.
The operator is responsible for an adequately stability and an appropriate fixation of the piping according to the
state of the art. To facilitate the installation and maintenance shut off valves should be installed right before
and after the pump. The nominal width of the connection pipes has to be chosen in accordance to the
connections of the pump. A smaller piping can cause cavitation (suction line) as well as a loss of performance
(suction and discharge line). In case the pipe is too big, the dry suction capacity of the pump can decrease.
Connect the suction line to the lower connection in the center housing [4]. Seal the suction line diligently;
hosepipes should be suitably armoured. A suction line continuously rising will prevent the formation of air locks
in the line which would affect the suction lift.
8
The air inlet [19] is located in the middle of the center housing [2]. Before installation, make sure that the air
supply pipe is free of solids. To supply the pump with driving air sufficiently, the pipe diameter should match
the size of the air inlet. Take care that no dirt or particles can intrude into the pump during the connection, as
these can accumulate inside the pump and can cause malfunctions. An air filter [24] directly behind the air inlet
[23] (not included in E 08 and E 10) prevents the entry of bulk particles.
The integrated air control system PERSWING P® [26] is a precision-control that requires oil-free, dry and clean
compressed air for optimal function. If humidity is expected, a water separator or air dryer has to be fitted to
protect the pump from blocking by ice. The ideal condition is the dewpoint of air at -20°C. In humid
surroundings, icing from the outside may occur despite the driving air is dried. If so, a prolonged waste-airexhaust (ca. 500 mm by pipe or hose) can be helpful. When installing the pump into boards or cabinets, it has
to be ensured that cold air does not get caught behind the muffler. In applications with a tendency to freezing
at the waste air exhaust, good experiences in practise have been achieved by pre-heating the driving air to
increase the distance to the dew point of the air. Doing so, it has to be considered that the driving air
temperature generally may not exceed 50°C to avoid expansion and sticking effects on the air side. This max.
air temperature is a well valid when using a compressor producing warm air which is e.g. often true for truck
compressors.
The pressure of the driving air should be limited to the amount required to meet the performance needed.
Excessive pressure increases both the air consumption and the wear of the pump. The pump is regulated by
tuning the flow rate of the air. For a proper operation at the lower performance range the regulation via a
needle valve is recommended. An empty pump has to be driven slowly (e.g. via a needle-valve). The pump
starts automatically. Pumps of the E-Series are self-priming when dry, thus it is not necessary to fill the suction
line of the pump. The suction lift capacity of a liquid-filled pump, however, is much higher. The pump is
appropriate for running dry during slow operation. Dry running at high stroke frequency causes premature
wear. The pumps can briefly (up to max. one hour) be operated against a closed discharge line. Throttling on
the suction side may damage the pump. When the pump operation has been stopped by a closed discharge,
the pressure equilibrium of the diaphragms must be ensured. This can be achieved by keeping the pump
connected to the air supply pressure; for longer stoppage, the pump must be released from the pressure within
the system on both fluid side and air supply side.
Torque values
Immediately before putting the pump into operation as well as after some hours of pumping, the
housing bolts [19] have to be fixed according to the torque data of the following schedules, as
the elements of construction "settle". The valve stops discharge valve [9] and the plugs [11/13]
have to be fixed too. Fixing all these parts is necessary as well after periods of stoppage, at
temperature variations, after transport and dismantling the pump. In case of temperature varying
between extremes or high temperature difference between the liquid and the surrounding, the
housing bolts should be controlled more frequently (interval proposals are available on request).
The following schedules show the torque values of the pump housing bolts, of the damper
housing bolts (when using a pulsation damper of the ET-Series) and of the optional flange
connection (optional equipment codes F3/F4/F5).

Installation, operation, and maintenance by qualified staff only.
Before start-up of the pump anyone should acquaint oneself with the explanations of the
chapter troubleshooting (see pages 14/15). Only by this the defect quickly can be realized
and eliminated in case of trouble. Problems which cannot be solved or with an unknown
reason should be passed on to the manufacturer.
Before any maintenance and service procedures arising on the pump or on the optional
equipments, the complete installation has to be turned off and protected against accidental
turn on. This is possible by a lockable emergency stop for the air supply of the pump.
Additional a danger sign against restart should be attached.
Pressure tests of the plant a pump is included in may only be carried out with the pump
disconnected from the pressure on both ports or by using the pressure the pump develops
while operating. The load of a pressure in the plant may damage the pump.
Pump must not be operated with a positive suction pressure.
Depending on the conditions of operation, the liquid conveyed might escape from the pump
through the muffler in case of a diaphragm rupture (in this case muffler has to be replaced).
For further safety requirements the optional equipment diaphragm monitoring and barrier
chamber system are recommended.
In case of a diaphragm rupture, it might be possible fort he fluid pumped to intrude into the
air side of the pump. In very adverse conditions - e.g. pressure within the fluid system during
stopped air supply - the fluid might as well find its way into the air supply lines. To protect
other devices like pulsation dampers or even pneumatic valves, it is recommended to protect
the air supply line accordingly, e.g. via a non-return valve. This would as well avoid polluting
the air supply line.
The state of the muffler has to be inspected regularly, as a blocked muffler can be forced out
of the pump. If this happens, damages of properties and/or persons cannot be excluded.
If the product tends to settle, the pump has to be flushed regularly. For larger solids a filter
has to be installed in the suction line.
In case of delivery of hot liquids the wetted pump must not standstill for a longer time,
because it could lead to temporary leaks in the valve area and to a blockade of the air control
system.
The relevant effective security advises have to be respected.
Pools of liquid which appear in the near outer area of the pump have to be inspected on
danger potential, if necessary safety measures are to be taken.
Chemical and biological reactions in the product chamber of the pump (mixture of different
substances) and the freezing of the liquid have to be avoided.
Before starting to disassemble the pump, take care that the pump has been emptied and
rinsed. Both ports piping are to be closed and drained if applicable. Further the pump has to
be cut off from any energy on the air and product side. If the pump is being deported from the
plant, a reference about the delivered liquid has to be attached.
Please respect the relevant additional security advices, if the pump has been used for
aggressive, dangerous or toxic liquids (e.g. suitable protective equipment according to the
safety data sheet of the liquid). In case of a diaphragm rupture, it is possible that residues of
the liquid remain behind the diaphragms, in the area of the air control system and at the
muffler, despite of several flushing processes. Hence, appropriate safety equipment
according to the safety data sheet of the liquid is indispensable.
Before putting the pump back into operation, the tightness of the pump has to be checked.
Air-operated diaphragm pumps can lead to bruises when lifting, sinking or assembling them.
Appropriate accessories and safety equipments are to be used. Big and heavy modules have
to fixed and secured to lifting gears when transporting/replacing them.
Especially when deliver critical liquids, wear parts, like diaphragms, should be replaced
within a preventive maintenance.
The use of non-original ALMATEC spare parts and structural changes lead to the lapse of
the warranty immediately. When operating such a pump, damages of properties and/or
persons cannot be excluded.
The operation of the pump with nitrogen as driving gas is possible. In closed rooms sufficient
ventilation must be provided.
Possible electrical connections (e.g. when using optional equipment with controllers) may be
executed by a qualified person only. The regulations of the respective manufacturers are to
be followed.
At any work arising it has to be made sure that no explosive atmosphere can appear.
Appropriate safety equipment is recommended.
Procedure for pump return: According to the requirements of our 14001-certification, every
unit which is send to ALMATEC for diagnosis or maintenance reasons has to be
accompanied by a filled out decontamination-sheet. Otherwise a processing is not possible.
The decontamination-sheet is enclosed to this manual. Please pay attention to the further
safety regulations.
Using as submersible pump
Consider the following advises when using an E-Series pump as a submersible pump: When immersing an airoperated diaphragm pump, it must generally be ensured that the waste air is deducted above the fluid level
with a pipe or similar. The pump must be located vertically upright to guarantee proper function. Minute
leakage on the air inlet or outlet can block the air valve. The pump must be disconnected from the pressure
within the system during standstill. When choosing the pump type, it must be taken into consideration that all
external parts - even those non-wetted during standard operation - like covers, shock absorbers, connections
etc. must be resistant to the fluid pumped. Please consider as well that depending on the material, the pump
must be weight down resp. fixed.
Additional temperature hints
The temperature and pressure limitations listed on page 5 are solely based on mechanical temperature limits
of the housing material used. Depending on the fluid pumped, the maximum safe operating temperature of the
housing material can be reduced significantly.
A general aspect of lower temperatures is, that below 0°C cold-brittling of the elastomers used within the
pumps can results in accelerated wear. Regarding the housing materials, please note that PE - other than PP keeps its mechanical strengths at low temperatures and PTFE keeps mechanically stable as well for an
extended temperature range. ALMATEC pumps of the E-Series can therefore be operated safely as well within
low-temperature installations: However, with liquids below 0°C accelerated wear of internal parts has to be
accepted. Moreover, freezing, bogging or crystallisation of the fluid pumped must be avoided, especially within
the pump. Emptying the pump via the drainage system (optional equipment code R) may be a useful tool to
assist this.
Please consider, that viscosity and specific gravity of most fluids change with temperature (most often
increasing at lower temperature). Depending on the application, this fact may not only result in result in a
reduced flow rate, the pump may even be unable to prime the thicker and/or “heavier“ fluid any more.
In case of varying application temperatures, the housing bolt tension has to be controlled very thoroughly, as
variations like these can change the effective tension of the housing bolts via the different thermal expansion
characteristics of single.
Providing spare parts
We recommend having spare part kits S on stock. These include the relevant spare parts for your pump.

Disassembly
When dismantling a pump the mentioned procedures and safety notes on the pages 9-11 have to be
considered generally. Among the different sizes of the E-Series - E 15 to E 50 - only the number of housing
bolts [19] varies. Besides, for the sizes E 08 and E 10 the shaft [20] additionally functions as the pilot piston for
the air-valve. In these pumps E 08 and E 10, there are no shaft piston rings [22] and no set screws [21] nor an
air filter [24]. Please keep these differences in construction in mind when reading the following dismantling
instructions.
The general design of the ALMATEC E-Series is simple. Two tools are delivered along with every pump. The
plastic one of these is designed for the mounting of the air-valve [26], the other one for the mounting of valve
seat [16]. Further special tools are not required.
Take the cover [3] out of the side housings [1], to get access to the
housing bolts [19]. Unscrew the housing bolts [19] on one side using a
socket wrench, remove tension disc [2] first and side housing [1]
second. Work carefully to ensure that the sealing surfaces in contact to
the diaphragms are not damaged. Carefully draw the housing bolts [15]
out of the pump and remove the second cover [2]. The center housing
[4] and both side housings [1] are removeable now. Remove the sleeve
[5] out from the side housing [1]. Take the O-rings sleeve [6] out of the
center housing [4] and both side housings [1] for a possible renewal.
For further dismantling of the side housings [1], screw out the valve
stop, discharge valve [9] with an appropriate wrench (figure 12.1).
Alternatively, you can stick two housing bolts [19] into the holes in the
valve stop [9] and loosen the valve stop with a third housing bolt [19]
fixed in between the others. Take out the ball valve [15] resp. cylinder
valve [15] and the O-ring, valve stop, discharge valve [10].
fig. 12.1
fig. 12.2
fig. 12.3
fig. 12.4
Use the metallic mounting tool to unscrew the valve seat [16] (figure
12.2/12.3). The plug, side housing [11] can be unscrewed the same way
as described for the valve stop [9]. Take care of O-ring plug side
housing [12]. Loosen the thread bolt [8] with a screw-driver. Remove
lock bolt [7] and afterwards ball/cylinder valve [15]. Turn the mounting
tool and screw the valve seat [16] into the side housing [1] (figure 12.4).
The valve seat [16] can now be removed from inside the side housing.
fig. 12.5
Screw one diaphragm [18] left-turning off the shaft [20] and pull the other diaphragm [18] ] together with the
shaft [20] out of the center housing [4]. Take out set screws shaft [21] of the diaphragms [18] by using a
hexagon socket key (figure 12.5). Remove both parts of the shaft piston rings [22] from their grooves carefully
(figure 13.1); do not damage the edges in the center housing, a re-assembly of the same piston rings is
impossible, they have to be replaced. Unscrew the muffler [25], the air inlet [23] and the air filter [24] out of the
®
center housing [4]. To remove the PERSWING P air control system [26], screw off both end caps using the
plastic mounting tool delivered with the pump (figure 13.2). Take out main and pilot piston. Push out the air
valve housing with the mounting tool turned around (figure 13.3).

For the installation of the PERSWING P air control system [26], first screw in one end cap flushly into the
center housing [4]. Insert one of the six O-rings air-valve housing [27] into the end cap from the inside.
Moisture the four O-rings [27] of the air-valve housing with a bit of water and push the housing into the center
housing [4] using the mounting tool. Take care that it slips in softly. Do never insert the housing violently with a
hammer. In case the housing cocks or hardly gets in, take it out again completely and start again. Insert the
main piston and the pilot piston. Lay the sixth O-ring [27] on the edge of the air valve housing and screw in the
second end cap.
To assemble new piston rings [22] (pump sizes E 15 - E 50 only),
carefully shape them like kidneys with locking ring pliers and insert the
rings into the grooves in the center housing [4] (figure 13.4); completely
press the rings into the grooves smoothly using some round tool.
Abb. 13.4
Screw the set screws [21] into the diaphragms and tighten them. Fix the
diaphragms [18] completely into the shaft [20] with the set screws [21].
Adjust the bores in the center housing [4] to the diaphragm on both sides
(turn slightly backwards if necessary). The sealing surfaces of the
diaphragms and the side housings [1] have to be absolutely clean and
undamaged; mere small scratches can cause leaking (if necessary,
smoothen the housing surfaces carefully with fine sandpaper).
When assembling the housing bolts [19] pay attention to the different lengths of the threads located on both
sides. Push a spring washer on the side with the shorter thread and screw on the nut to the stop.
Cautiously push the O-rings sleeve [6] into the side housings [1] and the center housing [4] (avoid bending the
rings by all means! If necessary, moisture and softly twist the rings). When installing the valve stop, discharge
valve [9] always start with inserting the O-ring, valve stop discharge valve [10] into the side housing [1]
carefully, do NOT shove the O-ring onto the valve stop [9]. It has to be ensured that the O-ring is in direct flat
contact to the horizontal surface at the end of the thread (press in with an appropriate round stick if necessary).
When building in cylinder valves, take care that these valves [15] are set into the valve seat [16] with flat side
first. Afterwards insert lock bolt [7] and bolt together with the thread bolt [8]. Shove one diaphragm [18] into the
center housing [4], lay the side housing [1] and the tension disc [2] onto the diaphragm and fix its position with
housing bolts [19]. After that, shove the other diaphragm [18] into the center housing [4] and carefully push the
housing bolts [19] completely through the center housing [4] [slightly turning the bolts helps them to find their
way]. Take care, that the diaphragms [18] are not damaged. Adjust the second side housing [1] and the
tension disc [2]. Fix the housing bolts [19] crosswise evenly according to the given torque values until the side
housings [1] are situated on the center housing [4]. Any further tightening of the bolts does not improve sealing
but can deform the housing! Before putting the pump back into operation, the tightness of the pump has to be
checked.

Optional equipment
For special requirements ALMATEC pneumatic diaphragm pumps of the E-Series can be furnished with
several optional equipment. The pump code informs which of these are included in the pump. The code is
noted on the identification plate on the pump. For the barrier chamber system (option code BS) a separate
manual is available.
Stroke counting (option code C 2, C 3, C 4, C 9, C 10)
Code C 2 / C 3 / C 4
A sensor [50] is installed in the center pump housing [4] to count the strokes.
The diaphragm movement is scanned without contact by this sensor: a safe
form of monitoring totally independent of external influences and the pump's
mode of operation. The issued sensor pulses can be output to existing detectors
or to a stroke counter (can also be supplied). When the preset value is reached,
the stroke counter outputs a signal which can then be processed further, for
instance in order to shut down the pump via a solenoid valve.
 C2
 C3
 C4
The stroke counting system is available in three variations:
Stroke sensor (Namur), also for explosion-proof zone
Stroke counting system complete with sensor and stroke counter
Stroke counting system complete with sensor, stroke counter and controller for
explosion-proof zone
In case only the sensor is included (code C 2), it has to be connected to an existing controller with Namur inlet.
For applications an explosion-proof device is required for (code C 4) the intrinsically safe controller has to be
installed between the sensor and the counter. The wiring diagram and technical data can be found on the
electric units themselves. For further details, please refer to the data delivered by the manufacturers of the
components. The controllers have to be installed in a suitable cabinet.
Code C 9 / C 10
Differently from the optional equipment codes C 2 - C 4, the strokes of the pump are registered pneumatically
on the codes C 9 / C 10. The pressure switch registers the changes in pressure within the air chamber behind
one of the diaphragms and it converts the pneumatic impulse into an electrical signal.
The pneumatic stroke counting system is available in two types:
 C 9 consist of:
pressure switch, cpl. mounted, 1 – 10 bar
socket with cable 5 m
adaptor elbow NPT ¼ (or adaptor straight for pump sizes E 08 / E 10)
hose DN 4/6, 2,5 m
 C 10 consist of:
as C 9 and a stroke counter
For assembly screw the adaptor elbow (or adaptor straight for pump sizes E 08 / E 10) into the additional air
connection of the pump (it is possible that the adaptor is already installed). The position of the air inlet varies
depending on the pump type and the pump size (see comments below). Link up the adaptor and the pressure
switch with the hose. Connect the socket to the electrical connection plug of the pressure switch and the cable
to existing registering devices (code C 9) resp. to the enclosed stroke counter (code C 10). Technical data,
connection schemes and further details can be found in the technical documentation delivered by the
manufacturers of the pressure switch and the stroke counter.
!!!
22
The pneumatic stroke counting system requires a minimum air pressure of 1.5 bar for
optimal function!
The air inlet for the pneumatic stroke counting system must not be confused with the actual air inlet of the
pump. Therefore, you will find some advises adapted to the pump type and the pump size.
A = Air inlet for the pump, B = Air inlet for the pneumatic stroke counting system

Diaphragm monitoring (option code D 1, D 3)
Although ALMATEC diaphragms with integrated metal core are designed for an
optimum service life, the diaphragm remains a wear part. If it breaks, liquid can leak
into the center housing and possibly emerge through the muffler. This can be
prevented simply and effectively with the ALMATEC diaphragm monitoring.
A capacitive diaphragm sensor is mounted in the muffler [25] of the pump, which
registers any liquid approaching the sensor, no matter whether the liquid is conductive
or not. Hence, a fast reaction to a damage of a diaphragm becomes possible.
However, it has to be considered, that the diaphragm monitoring possibly cannot
prevent that liquid can leave the pump via the muffler. For higher safety requirements
the ALMATEC barrier chamber system (optional equipment code BS) is
recommended. In case of humid surrounding air a false alert may occur despite operating the pump with dried
compressed air.
The diaphragm monitoring system is available in two variations:
 D 1 Diaphragm sensor (Namur), also for explosion proof area
 D 3 Diaphragm monitoring system complete with sensor and controller
The diaphragm sensor can either be connected to an existing controller with Namur inlet (code D 1) or to the
controller included (code D 3). The wiring diagram and technical data can be found on the controller itself. For
further details, please refer to the data delivered by the manufacturers of the components. The controllers have
to be installed in a suitable cabinet.

Draining system (option code R 1, R 2, R 3, R 4, R 5, R 6)
A pump equipped with the unique ALMATEC draining system can be emptied
along with an inclining discharge line while being installed within the plant. The
system is not appropriate to flush the pump with another liquid, nor from suction
nozzle nor from discharge connection. It consists of a bypass-system in the side
housings [1], which can be activated by manual valves (code R 1/R 2/R 5) or
pneumatically (code R 3/R 4/R 6). Open the manual valves (code R 1/R 2/R 5) by
approx. 10 mm by turning to the left (Attention: As there is no blocking of the
valves, it has to be ensured not to take them out completely). The pump should be
kept in operation meanwhile. Slow down the pump slowly and finally stop it. The
drawing on the left illustrates the connection schedule for the air supply of a pump
with the pneumatic draining system (code R 3/R 4/R 6, minimum air pressure 3
bar). By attaching a 4-2-way valve (not included in the delivery), the draining
system can be activated automatically when cutting off the pump. The O-rings
side housing are made of EPDM (code R 1/R 3), FEP (code R 2/R 4) or NBR (code R 5/R 6).

ALMATEC Pulsation Dampers, ET Series and ET-F Series
The ALMATEC pulsation dampers series ET and ET-F represents the latest generation of active pulsation
dampers. They are specially designed to be used along with ALMATEC air-operated double diaphragm pumps
of the E-Series. A general aspect to be considered is, that a pulsation damper decreases the total capacity of
the system depending on the point of operation.
Before putting an ALMATEC pulsation damper into operation, make sure, that the materials of construction are
resistant to the chemical to be pumped. To check this, the exact damper code is required. This code, the serial
number and the year of construction are noted on the identification plates on the damper itself.

Max. operating temperature:

for damper housing in PTFE size ET 10 100°C, for the other sizes 120°C (with
damper head in PE conductive 80°C)
For inflammable liquids as well as for applications in explosion protected areas, only dampers made of
conductive plastic materials (code F resp. U) may be used. It is not necessary to ground the damper
separately, as the damper is connected conductively to the E-Series pump, which is conductive and has to be
grounded itself (please see ATEX hints on page 4).
In general, pump and damper are dispatched completely mounted. Still, they can be packed in separate boxes,
especially for the bigger sizes. If so, the damper has to be screwed into the thread at the top of the center
housing carefully, but only until the damper is in contact with the pump. Exceeded tightening may damage the
thread. Besides, a correct positioning of the O-ring [10] within the groove has to be ensured.
An ALMATEC ET-damper can easily be attached to an E-Series pump at any time without changes of the
piping, provided that the pump is configurated with product ports both horizontally. Make sure that the plug,
center housing (Pos. 13 in the exploded view of the pump) is in the right position. For pumps delivered without
dampers, this plug can be found at the bottom side of the pump generally. Therefore, the center housing has to
be turned 180°, to get the plug to the top of the pump. Take the plug out, insert the flange-O-ring [10] and
screw the damper onto the pump. When dismounting a pump which is already being in use, take care of the
warning advices on pages 8/9 of this manual.
Before connecting the pump, take the yellow blind plugs out of air inlet which is located on the top of the
damper head [3]. For correct operation, the damper absolutely needs an air-supply of its own, which has to be
taken from the air-supply of the pump. Pump and pulsation damper have to be connected to the same air
pressure. No stop or regulating valve may be placed between pump and damper. The driving air has to be oilfree, dry and clean. The damper requires a minimum counter pressure of at least 1 bar for optimal function.
Together with the pump an empty damper has to be driven slowly. The dampers are self-regulating for all
28
changing operating conditions.
 Do not use any threadseal for the connection of pump and damper, otherwise the
threads could be damaged.
 Before putting the pulsation damper into operation as well as after some hours of
operating, the housing bolts [6] have to be tightened according to the torque data of the
following schedule, as the elements of construction tend to "settle". Fixing the bolts is
necessary as well after longer periods of stoppage, at extreme temperature variations,
transport and after dismantling.
 Pressure tests of the plant a pump and a damper are included in may only be carried out
with the aggregate (pump and damper) disconnected from the pressure on both ports or
by using the pressure the aggregate develops while operating. The load of a pressure in
the plant may damage the pump and the pulsation damper.
 Before starting to disassemble the pump, take care that pump and damper have been
emptied and rinsed. Further both have to be cut off from any energy on the air and
product side. If pump and damper is being deported from the plant, a reference about
the delivered liquid has to be attached.
 Please respect the relevant additional security advices, if the pump and the damper have
been used for aggressive, dangerous or toxic liquids.
 Before putting the pump and the damper back into operation, the tightness of both has to
be checked.
 For further warning instructions, please refer to the pages 9-11.

Hints for disassembly of an ET pulsation damper
Pull out the cover [5]. Unscrew housing bolts [6] carefully. After that, all parts can be removed. Screw the
diaphragm [2] off the actuator shaft [7]. A re-assembly of used piston rings [8] is impossible; they have to be
replaced including the O-rings underneath. To assemble new piston rings [8] carefully shape them like kidneys
with locking ring pliers and insert the rings into the grooves; completely press the rings into the grooves
smoothly using some round tool.

Additional hints for pulsation damper series ET-F (flange version)
Beside the screwed pulsation damper as standard flange versions (series ET-F) are available also. In general,
pump and damper are dispatched completely mounted. Still, they can be packed in separate boxes, especially
for the bigger sizes. If so, use the attached nuts, set screws, washers and discs [11-14] to flange the damper to
the pump.
