Description
3.4 Function
3.4.1 Principles of Vacuum Pump Operation
The main purpose of a vacuum pump is to reduce the pressure in a vessel or a closed system.
The degree of pressure reduction is dependent upon the requirements of the application and
the type of vacuum pump employed.
3.4.2 Working Principle of Rotary vane pumps
Pressure reduction in a closed system is accomplished by repeatedly removing a portion of the
original volume of gas contained in the system. Removal is performed by the action of the
rotating elements of the pump which cause a given space to be successfully enlarged and
diminished. Figure 2 illustrates a chapter through a typical stage of rotary-vane pump. Note that
this figure is not intended to illustrate exactly the internal components of the pumps; its purpose
is to illustrate the general operating principles of vacuum pumps.
Fig. 2 Rotary vane pump Principle
The rotary action of the pump creates a hollow space of chamber (1) which expands as the
pump rotates. As the chamber expands, the pressure in the chamber decreases. As a result,
gas is drawn into the chamber due to the difference in pressure between the chamber and the
inlet (4) to the chamber (The inlet is the only place where gas can flow into the chamber). Once
the vane (3) moves past the inlet (4), it seals the inlet against the chamber (1) and the gas
becomes trapped between the vanes (2 and 3). The chamber (1) formed by the enclosed space
between the vanes then begins to decrease in volume as the rotor revolves, compressing the
gas. The pressure of the compressed gas becomes greater than atmospheric pressure. When
the vane (2) moves past the exhaust port (5) the compressed gas in the chamber is forced out
through the exhaust port. This expansion/compression cycle constitutes one complete cycle of
the pump operation. This cycle is repeated as the vane (2) passes the intake port and seals it
against the atmosphere. Therefore, two pump cycles are performed during each revolution of
the pump rotor.
3.4.3 Working Principle of Two-Stage Rotary vane pumps (CRVpro Series)
Two pump stages (fore-stage and high-stage) are arranged in series in order to improve the end
pressure and the pumping speed at lower pressures. The intake takes place in the first stage
(high-stage), the compression and the outlet in the second stage (fore-stage).
8
P1700011
Description
Fig. 3 Pre-stage / high stage
When in operation, the intake stage is at lower pressure and the exhaust stage is at higher
pressure relative to each other. Each stage contains a rotor assembly consisting of a rotor with
two vanes and a stator. The two rotors are combined on one shaft, and the two stators are
combined in a common housing. The pump shaft turns the rotors, causing the vanes in each
chapter to sweep the surface of their stators. The vanes are pressed against the stators by
centrifugal force. Each stage has an exhaust valve. Gas expelled from the first stage exhaust
passes through an interstage port to the intake of the second stage. The second stage
compresses the gas further, then expels it from the second stage exhaust valve to the
atmosphere. The oil carried along with the gas is separated out by a filter (available accessory).
An adjustable gas ballast valve is located in the pump’s exhaust stage. The purpose of the gas
ballast is to prevent vapours condensing in the vacuum pump. A dosed quantity of air (gas
ballast) can be let into the pump body during the compression by opening the gas ballast valve.
The function of the gas ballast valve is described more in detail in chapter 3.4.7 “Gas Ballast”.
Effects of Continued Pressure Reduction
The quantity of gas in the vessel (6) is reduced with each evacuation cycle. The gas remaining
in the vessel expands to fill the vessel and consequently with each cycle the pressure in the
vessel is reduced. This is a manifestation of Boyle’s Law which states that, for a constant
temperature, the volume of a body of gas is inversely proportional to its pressure; i.e., if the
volume is enlarged the pressure must be reduced.
As the amount of gas in the vessel is steadily diminished, its pressure is correspondingly
reduced. The action of the pump must therefore compress a successively smaller quantity of
gas with each cycle to something greater than atmospheric pressure in order to expel it from the
pump.
At the beginning of an evacuation sequence, the compression ratio is very small. In the first
cycle of operation the pump draws in a volume of gas at atmospheric pressure and expels it at
approximately atmospheric pressure. Since the exhaust valve is generally spring loaded to
provide a good seal, the pressure required to open it is somewhat greater than atmospheric
pressure.
Ultimate Pressure
As described previously, a quantity of gas is removed from the system with each cycle of the
pump. Therefore, the pressure of the gas remaining in the system is reduced with each pump
cycle. Since the pump can remove only a small portion of the gas with each pump cycle, it is
obvious that this method of evacuation can never completely remove all the gas in the vessel. In
addition to this, all the components of the system contain minute sources of gas leakage which
are impossible to seal completely against atmospheric pressure. Outgassing of materials within
the system provide additional sources of gas.
As a result, after prolonged pumping, a state of equilibrium is reached in which the gas
introduced from all the leakage sources is balanced by the ability of the pump to remove gas
from the system. This state of equilibrium is referred to as the ultimate pressure or blankoff
P1700011
9
Description
pressure of the pump and its system. No matter how much additional pumping time is provided,
no further reduction in system pressure will be accomplished once ultimate pressure is attained.
Intake Anti-suck back Protection
When power to the pump is turned off, this device closes automatically, maintaining vacuum in
the system being evacuated, and vents the inside of the pump to atmospheric pressure.
3.4.4 Oil Functions
WARNING !
Vacuum pump is shipped without oil inside to prevent possible spillage during
shipment. Oil must be added prior to use!
The oil fulfils the following functions in the vacuum pump:
· lubricating the sliding parts, such as rotor, vane, radial shaft seals
· sealing the moving parts against the stator wall to reduce leaks
· conducting the heat of compression to the metal walls (cooling)
The oil transports the polluted particles and corrosive media and thus effects continuous
cleaning of the internal surfaces.
3.4.5 Pump Lubrication
To ensure efficient operation and proper maintenance, and to minimize noise and oil vapors, it
is important to use the correct type and quantity of oil. Directorr™ Premium vacuum oil has
been especially developed to have the proper viscosity, low vapor pressure, and chemical
stability needed to produce peak pumping efficiency. The ultimate vacuum guarantee on Welch
pumps applies only when this oil is used. Each pump is supplied with sufficient oil for filling.
Additional oil is available. See chapter 8 Overview of Accessories.
3.4.6 Exhaust Filter
Any oil-sealed vacuum pump tends to discharge oil mist from its exhaust port when the pump
operates under high-flow conditions, such as when the pump’s intake is at or near atmospheric
pressure. Typically, oil mist in the form of a white puff of “smoke” can be seen from the exhaust
port when no filter is used. Once the vacuum level and the corresponding air flow through the
pump are reduced, very little, if any, oil mist will be emitted. An exhaust filter is recommended
for any vacuum pump installation where the pump operates at high intake pressures for a
prolonged period of time. Oil droplets entrained in the pump’s exhaust are removed by the
exhaust filter element. Use of an exhaust filter typically reduces or baffles pump noise as well.
Exhaust filters are sometimes referred to as oil mist eliminators. See chapter 8 Overview of
Accessories.
3.4.7 Gas Ballast
Condensates could have collected in the vacuum pump if:
· the vacuum pump is new
· it has not been used for long periods
· the pump's maximum tolerance of water vapour pressure has been exceeded
10
P1700011
Description
When pumping condensable vapours, they may be compressed during the compression phase
above the saturated vapour pressure and condense.
This causes considerable deterioration in the vacuum pump’s performance:
· ultimate pressure is not achieved
· corrosion occurs
· heavy oil contamination and formation of emulsions
CAUTION !
Operating with gas ballast increases the operating temperature of the vacuum pump
by 5 – 10 K.
The gas ballast valve can increase the pump’s water vapour tolerance. In many vacuum pump
applications the gases being pumped from a system are a combination of permanent gases and
undesirable vapours such as water vapour. Under some conditions, the vapours condense in
the second stage of the pump and contaminate the oil. The gas ballast valve reduces oil
contamination by decreasing or eliminating vapour condensation.
Vapour condensation is most likely to take place when the gas compression ratio is high, i.e.
when the pump compresses a relatively large volume of gas to a small volume. Whether or not
condensation takes place is dependent upon several factors, including the proportion of
permanent gases to vapours at the pump intake. If the gases being pumped consist entirely of
vapours, condensation will definitely occur unless the gas ballast valve is opened. The gas
ballast valve adds a small amount of air at atmospheric pressure to the gas being compressed
in the second stage. This reduces the compression required to push the gas out past the
exhaust valve (less reduction in volume is required), and therefore reduces or eliminates
condensation.
When the gas ballast valve is open, the pump has to work a little harder, resulting in a slight
increase in operating temperature. The increase in temperature is small, however, and is not
harmful to the pump. Also, the pump is slightly noisier, and the pump’s ultimate pressure is
somewhat reduced. Therefore, the gas ballast valve should be kept closed when it is not
needed. Note that the gas ballast is not equally effective on all different types of chemical
vapours, so it may not always eliminate condensation completely.
Should condensate form despite actuation of the gas ballast device, the suction port must be
closed and the pump operated with gas ballast for a lengthy period (about 2 hours).

5.4 General References
CAUTION !
On continuous operation it’s recommended to run the pump below 10mbar maximum
vacuum pressure.
According to its intended use the capacity of the vacuum pump depends on:
·
·
·
·
·
the kind of assembly
accessories
the oil used
additional connections
vacuum piping system
In addition, fail-safe operation is determined by the mode of maintenance. Elements such as
valves, filters, condensers should be provided as early as in the conception. The materials of
the vacuum piping should be selected in such a way that they will be resistant to the media to
be delivered!

5.5.2 Installation of the Grounding Plug
For
UL
ONLY RELEVANT FOR UL (115V, 230V / 60HZ) OPERATION
This product must be grounded. In the event of an electrical short circuit, grounding reduces
the risk of electric shock by providing an escape wire for the electric current. This product is
equipped with a cord having a grounding wire with an appropriate grounding plug. The plug
must be plugged into an outlet that is properly installed and grounded in accordance with all
local codes and ordinances.
Check with a qualified electrician or serviceman when the grounding instructions are not
completely understood, or when in doubt as to whether the product is properly grounded. Do
not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a
qualified electrician.
For 115V/60Hz version: this product is for use on a nominal 120-V circuit and has a grounding
plug similar to the plug illustrated in Fig 9. Only connect the product to an outlet having the
same configuration as the plug. Do not use an adapter with this product.
Fig. 8 Grounding plug illustration
For 230V/60Hz version: this product is for use on a circuit having a nominal rating more than
120 V and is factory-equipped with a specific electric cord and plug for connection to a proper
electric circuit. Only connect the product to an outlet having the same configuration as the
plug. Do not use an adapter with this product. When the product must be reconnected for use
on a different type of electric circuit, the reconnection shall be made by qualified service
personnel.
Use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle
that accepts the plug on the product. Make sure your extension cord is not damaged. When
using an extension cord, be sure to use one heavy enough to carry the current your product
draws. For lengths less than 25 ft, 16 AWG extension cords shall be used. An undersized
cord results in a drop in line voltage and loss of power and overheating.
WARNING !
Improper installation of the grounding plug is able to result in a risk of electric shock.
When repair or replacement of the cord or plug is required, do not connect the
grounding wire to either flat blade terminal. The wire with insulation having an outer
surface that is green with or without yellow stripes is the grounding wire.

Installation and Operation
5.6 Starting-up
Observe the basic safety instructions when using the pump.
Before using the pump for the first time, it is recommended to spend a few minutes inspecting
the pump and its electrical and vacuum connections. Please notice the information which are
listed in chapter 5 Installation and Operation.
1. Connect the power cord to the power outlet.
2. Recheck the oil level and add or remove oil as needed. How to do this see chapter 6.1 Oil
Level Control.
3. Close off the pump intake and the gas ballast valve, and run the pump at blankoff for a few
minutes. The gurgling noise should go away after a few minutes of running; it is caused by
the high volume of air that flows through the pump when the pump is first turned on. If the
gurgling noise does not stop, check the oil level again to see if it is low. Also check the
pump intake fitting to be sure that it is tight.
4. Once proper pump operation has been verified, the pump intake can be opened to the
vacuum system.
5. After running the pump for a few minutes, check the oil level again. If the level is too high or
too low, stop the pump, vent it to the atmosphere and add or remove oil as needed – see
chapter 6.3 Oil Change.
6. Before starting the pump when connection to the vacuum system, check all vacuum
connections.
CAUTION !
Check the oil level prior to switching on the vacuum pump!
5.7 Operating Temperature
The function of the vacuum pump filled with Directorr™ Premium vacuum oil is guaranteed
between ambient temperatures of 10°C and 40°C. The lowest starting temperature is 12°C. The
pump must be vented on the suction-side (suction port open).
WARNING !
In dependence on the operation mode, the casing temperature can reach 90°C.
Make sure that the vacuum pump has not been installed in an accessible area, and
make provision for a guard against contacts!
P1700011

Installation and Operation
5.8 Oil for Drawing off Oxygen
WARNING !
Pump should be not used for oxygen service! Oxygen at atmospheric pressure is
exceptionally dangerous!
For drawing off oxygen containing mixtures or pure oxygen the following must be taken into
consideration:
· Mineral oils are flammable
· The more they oxidise, the quicker they lose their properties. For this reason they
only can be used up to an oxygen percentage of maximum 30 per cent in the
medium to be delivered.
In order to prevent any accumulation of oxygen in the discharge space, neutral gas such as
nitrogen may be let in through a special inlet assembly. The percentage of oxygen is being
reduced. The added amount of gas should be 5 times as much as the percentage of oxygen.
CAUTION ! / WARNING !
There is a risk of explosion when pumping oxygen at a concentration above
30 percent.
5.9 Gas Ballast Control
The principle of the gas ballast is described in chapter 3.4.7 Gas Ballast.
To open or close the gas ballast turn the gas ballast switch to the position open or close.
Operation with gas ballast when drawing off condensable vapours
We suggest operation with the gas ballast valve open, provided that the composition of gas in
the vacuum pump to be drawn off is not known and cannot be ruled out.
If condensable gas and vapours are to be delivered, the latter or their condensates will mix with
the oil. As a result of this, the pump performance will degrade.
5.10 Closing down
A few simple precautions are necessary before performing a pump shutdown.
1. If a gauge is connected to the system, first isolate the gauge, then turn off the power to the
pump and open the system to the atmosphere.
2. If condensable media have been pumped, the vacuum pump must be run after pumping
with the gas ballast valve open and the intake pipe closed.
3. If the vacuum pump is not going to be used for a sometime after pumping aggressive or
corrosive media, or if it not going to be used for a long time, then proceed as follows:
·
22
If the pump oil is contaminated and the pump is going to be stored for a prolonged
period, the oil should be changed before the pump is stored. Even if a pump is
stored for a long period with oil initially in good condition, check the oil when the
pump is restarted, and change the oil if necessary.
P1700011
Installation and Operation
·
Close connecting ports with a rubber stopper or other suitable cover to protect the
pump against contamination. An intake screen is furnished to prevent loose particles
from entering.
WARNING !
Take appropriate safety measures in case of having delivered dangerous media!
5.11 Storage
The pumps are to be stored in a low-dust, interior room within the temperature range from + 5 to
+ 40 °C and at a relative air humidity < 90%.
Leave the protective elements on the suction and pressure ports. Another equally good
protection may be used.
If the pump oil is contaminated and the pump is going to be stored for a prolonged period, the
oil should be changed before the pump is stored. Even if a pump is stored for a long period with
oil initially in good condition, check the oil when the pump is restarted, and change the oil if
necessary.
5.12 Scrap Disposal
CAUTION !
The Rotary vane pumps must be disposed of in accordance with the 2012/19/EU
directive and the specific national regulations.
Contaminated Rotary vane pumps must be decontaminated according to the laws.
P1700011
23
Maintenance and Servicing
6
Maintenance and Servicing
Under normal operating conditions the maintenance of the rotary vane pump is limited to:
· external cleaning
· checking running noises
· checking the level and quality of the oil
· regular oil changes
These maintenance intervals must be specified according to the prevailing operating conditions
and adhered to. The bearings of the drive motors are life-long lubricated and so maintenancefree.
CAUTION !
Only perform the work that is described here, and that which is permitted to be done
by the user. All other maintenance and service work may only be performed by the
manufacturer or a dealer authorized by him.
Beware of the pump parts being possibly contaminated by hazardous substances.
Wear protective clothing if there is contamination.
WARNING !
During repair or maintenance work which could endanger people because of moving or
electrically live components, the vacuum pump must be made safe by removing the
mains supply plug from the socket or by switching off the main contractor and
preventing it from being switched on again!
6.1 Oil Level Control
CAUTION !
Check the oil level regularly!
The oil consumption varies according to the vacuum pump's operating conditions. In order to
keep the vacuum pump at all times in an optimum operating condition, the oil level must be
inspected at the oil sight glass. The oil level must at all times be showing between the upper
and lower markings on the oil sight glass. The oil must be topped up if the oil level falls to the
lower mark. We recommend to operate pump with oil filling at upper marking FULL. This
minimize the service needs and allows better dilution of contaminants.
When additional oil is required, use only Directorr™ Premium vacuum oil, pump performance is
not guaranteed with other brands of oil.

6.2 Oil Colour Check
WARNING !
The condition and quality of the pump oil have a substantial effect upon the
performance and operational readiness of the vacuum pump!
Comparing the colour of a sample of the pump oil with fresh oil provides an indication of the
contamination of the pump oil. You obtain the oil needed for testing from the oil drain aperture
with the vacuum pump switched off and at operating temperature.
Brown or black oil or oil smelling as if it has burnt must be removed from the vacuum pump.
Flush the vacuum pump and fill up with fresh oil.
6.3 Oil Change
WARNING !
If the vacuum pump has been used to pump media which are dangerous to health then
all measures must be taken to protect the service and operating personnel!
6.3.1 Draining the Oil
1. Block the inlet port and switch on the vacuum pump and let it work for about 10 minutes to
warm the oil.
2. Switch off the pump, disconnect from the power outlet and from the vacuum system.
3. Unscrew the oil drain plug from the pump casing while the pump is at operating
temperature.
4. Tilt the vacuum pump slightly, catches the oil in a suitable vessel and dispose of it in
accordance with the applicable regulations.
P1700011
25
Maintenance and Servicing
WARNING !
Avoid skin contact with the oil! Dispose of the oil in accordance with the valid
environmental protection regulations!
6.3.2 Filling up with Oil
1. Switch off the pump, disconnect from the power outlet and from the vacuum system.
2. Remove the oil fill plug.
3. Pour in the oil until it reaches the upper mark “FULL”.
4. Screw in the oil fill plug together with the seal once again.
5. Block the inlet port and switch on the vacuum pump and let it work for about 2 minutes.
6. Check the oil level when the pump is switched off, repeat if necessary.
WARNING !
Avoid skin contact with the oil! Wash hands thoroughly after handling. Keep out of
reach of children. Dispose of the oil in accordance with the valid environmental
protection regulations! Do not overfill, excess oil tends to be splashed out the pump
exhaust! Use only Directorr™ Premium vacuum oil.
For best dilution of contaminants, especially on chemical applications, we recommend to keep
always oil level at max.
6.3.3 Flushing
If the oil is heavily contaminated, the vacuum pump must be flushed, e.g.:
· heavy clouding by condensates
· suspended particles such as dust, fibres, abraded particles
· dark coloration of the oil
The flushing liquid should be the type of oil which is currently being used.
1. After the vacuum pump has been filled with fresh oil, allow it to warm up by running it with
the suction port closed. If you have established that the old oil, which you have previously
drained, was contaminated by condensate (e.g. water) then the gas ballast valve must be
open.
2. Drain the flushing oil. If the oil still appears heavily contaminated, the flushing procedure
must be repeated.
26
P1700011
Maintenance and Servicing
6.3.4 Frequency of Oil Changes
The oil change interval is completely dependent upon the running conditions of temperature,
operating pressure, hours of daily operation, and upon the materials pumped. Clean, dry air at
pressures below 0.7 mbar (50 mtorr) are the most forgiving conditions. To determine your own
oil change interval, visually monitor the pump oil conditions at regular intervals. If you suspect
harsh operating conditions, daily visual checks are recommended. When the oil becomes
cloudy, dark or includes particles of solids, it is time to change the oil.
Be sure to use only Directorr™ Premium vacuum oil. The ultimate pressure guarantee applies
only if this oil is used!
6.4 Shaft Seal Replacement
When the shaft seal in the mounting plate shows signs of excessive oil leakage, it should be
replaced.
Before attempting replacement of the seal, the pump must be disconnected from the vacuum
system and from the power outlet. A seal replacement kit is available. This kit contains the outer
lip seal assembly and gasket, which can be replaced in the field. See chapter 10 “Overview of
Spare Parts”.
6.5 Major Factory Repair
Repairs and maintenance going beyond the extent of the work described in the previous
chapters or reconditioning or modification may only be performed by the manufacturer or
authorized workshops.
Drain the oil before dispatching the pump and dispose of the oil according to the regulations.
The prerequisites for a handover are a complete and factually correct damage report, and a
clean pump. Clean the pump aggregate and the pump casing after pumping media which are
harmful to health and the environment. Fill up with sufficient oil to protect against corrosion
during transport!

The suction-side separator AKS prevents condensates from the vacuum systems
penetrating into the rotary vane pump. The horizontal arrangement of the separator
alongside the pump prevents fluids running back from the collector or condensate
vessel into the pump.

Area of
Application
The pressure-side separator AKD effectively reduces the oil mist emission from
the rotary vane pump's pressure port at high intake pressures.The horizontal
arrangement of the separator alongside the pump prevents fluids running back
from the collector or condensate vessel into the pump.
Maintenance
Maintenance of the pressure-side separator AKD is limited to simply emptying the
collecting vessel and changing the saturated filter cartridge.
Assembly AKD at rotary
vane pump:
The pressure-side separator (G) is
flanged directly to the pressure port
(B) of the rotary vane pump, using a
normal clamping ring (C) and a
centering ring with an O-ring (D).

Overview of Accessories
8.5 Sorption trap SOF
Mode of action
The gas flows from the recipient via the gas inlet into the sorption trap, passes by
the sorption agent, and reaches the outer cylinder to the gas outlet which is
connected to the pump. The oil particles fly against the flow direction out of the
pump and into the outer cylinder of the sorption trap. This provides the first of
opportunity for precipitation against the wall of the cylinder. After this, the oil
particles fly past the sorption agent which presents a very high affinity to
hydrocarbons. The particles will be attracted and bound by the sorption agent.
This leads to a reduction by approximately 3 powers in the partial pressure of the
hydrocarbons having a mass number of 40 or higher as compared to operation
without a sorption trap.
Assembly –
SOF at rotary
vane pump
Change of the
sorption agent
(molecular
sieve)
The connecting direction is indicated by an arrow (G) on the sorption trap. The
rotary vane pump and the sorption trap (A) are located next to each other on an
even surface. Initially fasten the sorption trap (A) to the metal hose (B) using the
centering ring with an O-ring (D) and the normal clamping ring (C). For connection
to the suction port (F) of the rotary vane pump, use the centering ring with wire
fabric and O-ring (E) available at the pump, and the normal clamping ring (C).
Connecting elements in DN 16 KF - see chapter 8.3 Inlet Condensor AKS 16.
When the sorption agent (molecular sieve) (1) is saturated, it is to be replaced.
Turn the sorption trap upside down and unscrew (8) the bottom flange (7) to
change the sorption agent. Now the clamping cover (3) is visible and must also be
removed. Drain the sorption agent from the trap and clean it. Fill in new sorption
agent and close the sorption trap in reverse order. The sorption trap is ready for
use again.
