3 Safety

Observe the safety notices in Chapters

7 Installation and connection

and

8 Operation

The pumps are produced in accordance with the generally recognized rules of engineering, as well as the occupational health, safety and accident prevention regulations. Nevertheless, dangers can arise during their use that lead to injuries to the user or third parties or to damage to the pump or other property.

Only use the pumps in perfect technical condition, for their intended purpose, safely and aware of the dangers and in observation of the operating instructions.

The components that are to be connected to the pumps must be designed according to the pneumatic data of the pumps.

When connecting the pumps to the electrical mains, observe the corresponding safety rules.

Personnel Make sure that only specially trained personnel or trained and instructed personnel work on the pumps. This applies, in particular, for connection and servicing work.

Working in a safety conscious manner

Make sure that the personnel have read and understood the operating instructions, particularly the chapter on safety.

Observe the regulations on accident prevention and safety during all work on the pumps and during operation.

Avoid contact with the heads and housing parts, as the pump heats up during operation.

When working on the pump, make certain that the pump is disconnected from mains and without power.

Classification of a pump environment

Use in a potentially explosive environment

Ensure that no hazards arise from flows when gas connections are open, from the effects of noise or from hot, corrosive, dangerous, and environmentally hazardous gases.

When classifying a pump environment in a potentially explosive area

(zone), observe the "Guideline for Preventing Danger from Explosive Atmospheres, with a Collection of Examples – Explosion Protection Guidelines – (EX-RL)".

If the situation relates to special cases or if doubt exists about the definition of the potentially explosive atmospheres, inform the regulatory authorities and have them make the decision.

The following applies for use in a potentially explosive environment consisting of gases, vapors and mists:

The lowest ignition temperature of the potentially explosive atmospheres that comes into question must be higher than the so-called "maximum surface temperature" of the pump.

According to DIN EN ISO 80079-36, the maximum surface temperature is the highest temperature that is achieved during operation under the most unfavorable conditions (but within the accepted tolerances) of a part or on a surface of the pump.

The maximum surface temperature is specified from the design of the pump and noted on the pump type plate as the temperature class.

Explosion protection The introduction of ignition sources such as sparks, open flames and hot surfaces may result in explosions in potentially explosive atmospheres.

Therefore, during transport, during installation and during all work on the device in the potentially explosive atmosphere:

Only perform work when there is no possibility of a potentially explosive atmosphere.

12 Translation of Original Operation and Installation Instruction, english, KNF 320945 04/21

Diaphragm pump N630 EX Safety

§ Only use tools and lifting gear that are approved for use in potentially explosive atmospheres.

Handling of hazardous media Upon breakage of the diaphragm and/or leaks, the transferred medium mixes with the air in the surroundings and/or in the pump housing. Make sure that a dangerous situation cannot arise as a result.

When pumping hazardous media, observe the safety regulations for the handling of said media.

Handling of combustible media Make certain that the temperature of the medium is always sufficiently below the ignition temperature of the medium so as to prevent ignition or explosion. This also applies for abnormal operating situations.

Note that the temperature of the medium increases when the pump compresses the medium.

Therefore, make certain that the temperature of the medium also remains sufficiently below the ignition temperature of the medium even when it is compressed to the maximum permissible operating pressure of the pump.

The maximum permissible operating pressure of the pump is stated in

Chapter 4 Technical data

Make certain that the permissible ambient temperature ( 4 Technical data )

is not exceeded.

Where applicable, also take into account external energy sources (such as radiated heat sources) that could additionally heat the medium.

In case of doubt, contact KNF Customer Service.

Environmental protection Protect all replacement parts in storage according to environmental regulations and dispose of all replacement parts according to regulations. Observe both the respective national and international regulations here. This applies in particular to parts that are contaminated with toxic substances.

EU/EC directives/standards See EC/EU Declaration of Conformity

Customer service and repairs The pumps are maintenance-free. However, KNF recommends periodic inspection of the pump for obvious changes in noise or vibration.

Only have repairs to the pumps performed by qualified KNF personnel.

Housings with electrically live components may only be opened by specialized personnel.

Use only genuine spare parts from KNF when performing servicing work.

Only have repairs to the motors performed by the responsible KNF Customer Service.

à Protect the compressors by means of a pressure relief device between the pressure-side connections of the compressor and the first shut-off valve.

WARNING

Risk of explosion during pressure limitation resulting from the medium mixing with the environment

à Make certain that there is no risk of explosion posed by the medium mixing with the environment.

Pump discharge

Decoupling

à If the pump is used as a vacuum pump, safely (with respect to medium and noise) drain the hot pump discharge that may, under certain circumstances, occur at the pneumatic outlet of the pump.

à KNF recommends mechanically decoupling the pump from the pipe system, e.g., through the use of flexible hoses or pipes. In this way it is possible to prevent the transfer of possible pump vibrations and noises to the system.

à Monitor the ambient temperature (compression heat, motor heat).

à Ensure sufficient cooling air supply.

Excessive pressure, with all of the associated hazards, can be prevented by means of a bypass line with a pressure relief valve between the pressure side and suction side of the pump. Further information is available from KNF Customer Service (contact data: see www.knf.com).

WARNING

Risk of dangerous gas mixtures during pump operation if diaphragm breaks

If the diaphragm should break, the medium will mix with the air in the compressor housing or in the surroundings.

à Stop pump immediately.

à Replace the diaphragm prior to further operation (see Chapter

9 Servicing

Pump standstill

Vapors as medium

Because the diaphragm is a wear part, diaphragm breakage may occur at any time.

à When the pump is at a standstill, establish normal atmospheric pressure in the lines.

à Preventing condensate from forming in the pump will extend the service life of the diaphragm. Therefore, only use a warm pump with saturated or nearly saturated vapors.

Operation with open suction-side gas connection can result in contaminants and objects being drawn in.

8.2 Information on switching the pump on and off

Switching on the pump

The pump must not be started up against pressure or vacuum during switch-on. This also applies during operation after a brief power failure.

à Ensure that normal atmospheric pressure is present in the lines when switching on.

Recommissioning

Inspecting the pump

Switching off the pump

à KNF recommends: When pumping corrosive media, flush the pump

before switching off (see Chapter 9.2.1 Flushing the pump

) to extend the service life of the diaphragm.

Establish normal atmospheric pressure in the lines (relieve pump pneumatically).

à Before recommissioning, observe the applicable standards, guidelines, regulations and technical standards at the electrical connection.

The ball bearings installed in the pump and in the drive motor are lubricated for life. This means that the bearings are coated with a high-quality grease with a high degree of purity and an ideal fill level by the bearing manufacturer at the plant. These bearings cannot be relubricated. The prescribed bearing replacement periods can be found in Chapter

9.1 Servicing schedule .

The duration of use of the bearing grease depends on many highly individual factors. The prescribed bearing replacement periods were specified under the assumption of normal ambient conditions. Factors that can make early bearing replacement necessary include dust or dirt that may get into the bearing, aggressive gases or vapors that may change the lubricating properties of the bearing grease, etc. It is the operator's responsibility to assess these factors.

Explosion protection

EXPLOSION PROTECTION!

The introduction of ignition sources such as sparks, open flames and hot surfaces can cause explosions in the potentially explosive area.

Therefore, when carrying out all work on the machine in the potentially explosive area:

– Do not start any work without a written permit.

– Only carry out work to the exclusion of a potentially explosive atmosphere.

– Only use tools which are approved for use in the potentially explosive area.

Failure to adhere to these instructions will lead to a loss of the explosion protection.

DANGER!

Danger to life from electrical current.

There is an immediate risk of fatal injury in case of contact with live parts. Damage to the insulation or individual components can mean danger to life.

Therefore:

– In case of damage to the insulation, switch off the power supply immediately and have repairs carried out.

– Have work on the electrical equipment carried out by qualified electricians only.

– When any work is carried out on the electrical equipment, disconnect it from the power and make sure it is free of voltage.

– Before carrying out maintenance, cleaning and repair work, switch off the power supply and secure it to prevent it from being switched back on.

– Do not jumper or disable any fuses or circuit breakers. When replacing fuses or circuit breakers make sure to adhere to the correct ampere rating.

– Keep moisture away from live parts. It can lead to a short circuit.

WARNING!

Risk of fatal injury from moving parts.

Rotating parts and/or parts which move linearly can cause serious injuries.

Therefore:

– Do not reach into moving parts or handle moving parts during operation.

– Do not open covers during operation.

Before connecting the explosion protected motor, check the following:

- do the ratings on the type plate match the mains voltage and frequency?

- does the explosion protection match the environment in which the motor is operated

(gas group, temperature class)?

The electrical connections are established using the terminal box. The connection diagram (wiring diagram) is inside the terminal box.

Optionally the motors can be supplied with a motor cable instead of with a terminal box ( catalogue).

If a standstill heating is present, the electrical controller has to ensure that the motor voltage and the heating voltage cannot be applied simultaneously.

The motor protection can be implemented with a motor protection switch or a thermal sensor (PTC, PTO,

PT100).

For self-ventilated, single-speed motors in S1 mains operation with low-load and infrequent starts not causing any significant heating, a motor protection switch is a sufficient measure to comply with explosion protection requirements (temperature class).

Exclusive protection by temperature monitoring with thermal sensor for all modes other than S1 is only permitted in connection with a certified triggering device. These triggering devices must have been certified and marked by a notified body according to directive 2014/34/EU. The devices must be included in the regular monitoring by the operator.

4.4 Obligations and conditions

Some gap lengths of the spark-proof gap of this equipment are greater, and some gap widths of the sparkproof gap are smaller than required in Table 2 of EN/IEC 60079-1:2007. For information regarding the dimensions, please contact the manufacturer.

To connect the pressure proof encapsulation, use screws with a yield point of at least 640 N/mm

Motors requiring direct temperature monitoring have to be monitored with a separately certified triggering device (see 4.3).

Make sure when operating a 3-phase motor with an external fan that the motor can only be run while the external fan is running. The external fan motor must comply with EPL Gb or Db.

Make sure not to exceed the permissible temperatures for the used components.

Only metal fan blades may be used if the temperature on the shaft journal in the fan blade area is >= 95°C during rated operation.

The manufacturer specifies the electrical parameters, the temperature class and the ambient temperature range of the respective version after a routine test.

2 Advice

2.5 Coupling selection

For a permanent and failure-free operation of the coupling it must be selected according to the selection instructions (according to DIN 740 part 2) for the particular application (see catalogue drive technology "ROTEX ® ").

If the operating conditions (performance, speed, modifications on engine and machine) change, the coupling selection must imperatively be reviewed.

Please make sure that the technical data regarding torque refer to the spider only. The transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his responsibility.

For drives subject to torsional vibrations (drives with cyclic stress due to torsional vibrations) it is necessary to perform a torsional vibration calculation to ensure a reliable selection. Typical drives subject to torsional vibrations are e. g. drives with diesel engines, piston pumps, piston compressors etc. If requested, KTR will perform the coupling selection and the torsional vibration calculation.

2.6 Reference to EC Machinery Directive 2006/42/EC

The couplings supplied by KTR should be considered as components, not machines or partly completed machines according to EC Machinery Directive 2006/42/EC. Consequently KTR does not have to issue a declaration of incorporation. For details about safe assembly, start-up and safe operation refer to the present operating/assembly instructions considering the warnings.

3 Storage, transport and packaging

3.1 Storage

The coupling hubs are supplied in preserved condition and can be stored at a dry and roofed place for 6 - 9 months.

The features of the coupling spiders (elastomers) remain unchanged for up to 5 years with favourable storage conditions.

The storage rooms must not include any ozone-generating devices like e. g. fluorescent light sources, mercury-vapour lamps or electrical high-voltage appliances.

Humid storage rooms are not suitable.

Please make sure that condensation is not generated. The best relative air humidity is less than 65 %.

3.2 Transport and packaging

In order to avoid any injuries and any kind of damage always make use of proper transport and lifting equipment.

The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise contractually agreed, packaging will follow the in-house packaging specifications of KTR.

4.2 Advice for finish bore

STOP

The maximum permissible bore diameters d (see chapter

1 - technical data) must not be exceeded. If these figures are disregarded, the coupling may tear. Rotating particles may cause danger to life.

•

Hub bores machined by the customer have to observe concentricity or axial runout, respectively

(see illustration 9).

•

Make absolutely sure to observe the figures for Ø d max

•

Carefully align the hubs when the finish bores are drilled.

•

Provide for a setscrew according to DIN EN ISO 4029 with a cup point or an end plate to fasten the hubs axially.

Illustration 9: Concentricity and axial run-out

The customer bears the sole responsibility for all machining processes performed subsequently on unbored or pilot bored as well as finish machined coupling components and spare parts. KTR does not assume any warranty claims resulting from insufficient remachining.

KTR supplies unbored or pilot bored coupling components and spare parts only upon explicit request of the customer. These parts are additionally marked with the symbol .

Reference to unbored resp. pilot bored coupling components with explosion protection marking:

Basically the company KTR supplies couplings resp. coupling hubs with explosion protection marking as an unbored or pilot bored type only on explicit request of the customer. The prerequisite is a declaration of exemption submitted by the customer assuming any responsibility and liability for remachining performed properly.

(KTR standard)

If a feather keyway is intended to be used in the hub, it should correspond to the tolerance ISO JS9 (KTR standard) with standard operating conditions or ISO P9 with complicated operating conditions (frequently alternating torsional direction, shock loads, etc.). The keyway should preferably be located between the cams.

With axial fastening via setscrew the tapped hole should be positioned on the keyway except for Al-D which should be positioned opposite the keyway.

The transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his responsibility.

4.3 Assembly of the hubs

 We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy before assembly.

Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft.

Please pay attention to the ignition risk in potentially explosive atmospheres!

Touching the heated hubs causes burns.

STOP Please wear safety gloves.

With the assembly make sure that the distance dimension E (see table 1 to 7) is observed to allow for axial clearance of the spider when in operation.

Disregarding this advice may cause damage to the coupling.

If used in potentially explosive atmospheres the setscrews to fasten the hubs as well as all screw connections must be secured against working loose additionally, e. g. conglutinating with Loctite (average strength).

•

Mount the hubs on the shaft of driving and driven side (see illustration 10).

•

Insert the spider or DZ elements into the cam section of the hub on the driving or driven side.

•

Shift the power packs in axial direction until the distance dimension E is achieved (see illustration 11).

•

If the power packs are already firmly assembled, shifting the hubs axially on the shafts allows for setting the distance dimension E.

•

Fasten the hubs by tightening the setscrews DIN EN ISO 4029 with a cup point (tightening torques see table 8).

 If the shaft diameters with inserted feather key are smaller than dimension d

(see table 1 to

7) of the spider, one or two shaft ends may protude into the spider.

4.4 Assembly of taper clamping sleeve

Assembly of taper clamping sleeve:

Illustration 11: Assembly of coupling

Clean the contact surfaces of the taper clamping sleeves and of shaft and hub and afterwards apply thin fluid oil lightly (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).

The taper clamping sleeves have got axially parallel, cylindrical and smooth tapped blind holes. Only half of these holes are located in the material of the sleeve. The other half located in the hub has got threads.

Fit the coupling element and the taper clamping sleeve into each other, make sure that the bores cover each other and tighten the setscrews lightly. Fit the coupling element along with the taper clamping sleeve on the shaft and tighten the setscrews at the tightening torque specified in table 10.

During the screwing operation the hub is mounted onto the taper sleeve and thus the sleeve is pressed onto the shaft. By light blows of the hammer the taper clamping sleeve must be pushed further into the taper bore by means of a suitable sleeve. Afterwards re-tighten the setscrews at the tightening torque specified in table 10. This process must be performed at least once.

After operation under load of the drive for a short while please inspect if the setscrews have unscrewed.

Axial fixing of the Taper Lock hub (coupling hub with taper clamping sleeve) is obtained by proper assembly only.

If used in potentially explosive atmospheres the setscrews to fasten the taper clamping

! sleeves have to be secured against working loose additionally, e. g. conglutinating with

Loctite (average strength).

Taper clamping sleeves used without a feather key are not permitted in potentially explosive atmospheres and are thus not provided with a respective explosion protection marking.

Oils and greases with molybdenum disulphide or high-pressure additives, additives of

Teflon and silicone as well as internal lubricants reducing the coefficient of friction significantly must not be used.

4.5 Displacements - alignment of the couplings

The displacement figures specified in tables 11 to 13 provide for sufficient safety to compensate for external influences like, for example, heat expansion or foundation settling.

In order to ensure a long service life of the coupling and avoid risks with the use in potentially explosive atmospheres, the shaft ends must be accurately aligned.

Please absolutely observe the displacement figures indicated (see table 11 to 13). If the figures are exceeded, the coupling will be damaged.

The more accurate the alignment of the coupling, the longer is its service life.

If used in potentially explosive atmospheres for explosion group IIC, only half of the

Please note: displacement figures (see table 11 to 13) are permissible.

•

The displacement figures specified in table 11 to 13 are maximum figures which must not arise in parallel. If radial and angular displacements arise at the same time, the permissible displacement values may only be used proportionally (see illustration 15).

•

Please inspect with a dial gauge, ruler or feeler whether the permissible displacement figures of tables 11 to

13 can be observed.

5 Start-up

Before start-up of the coupling, inspect the tightening of setscrews in the hubs, the alignment and the distance dimension E and adjust, if necessary, and also inspect all screw connections for the tightening torques specified.

Finally the coupling protection against accidental contact must be fitted. It is required in accordance with

DIN EN ISO 12100 (Safety of Machinery) and directive 2014/34/EU and must protect against

•

access with the little finger

•

falling down of solid foreign objects.

The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with

DIN EN ISO 13857.

The cover must be electrically conductive and included in the equipotential bonding. Bellhousings (magnesium share below 7.5 %) made of aluminium and damping rings (NBR) can be used as connecting element between pump and electric motor. The cover may only be taken off with standstill of the unit.

If the couplings are used in locations subject to dust explosion and in mining the user must make sure that there is no accumulation of dust in a dangerous volume between the cover and the coupling. The coupling must not operate in an accumulation of dust.

For covers with unlocked openings on the top face no light metals must be used if the couplings are used as equipment of equipment group ll (if possible, made of stainless

steel).

If the couplings are used in mining (equipment group l M2), the cover must not be made of light metal. In addition, it must be resistant to higher mechanical loads than with use as equipment of equipment group ll.

During operation of the coupling, please pay attention to

•

different operating noise

•

vibrations occurring.

If you note any irregularities with the coupling during operation, the drive unit must be switched off immediately. The cause of the breakdown must be specified by means of the table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential breakdowns specified can be hints only. To find out the cause all operating factors and machine components must be considered.

Coating of coupling:

If coated (priming, paintings, etc.) couplings are used in potentially explosive atmospheres, the requirements on conductibility and coating thickness must be considered. With paintings up to 200 µm electrostatic load does not have to be expected. Paintings and coatings exceeding a thickness of 200 µm are generally impermissible for potentially explosive atmospheres. This also applies for multiple coatings exceeding an overall thickness of 200 µm. Make sure with painting or coating that the coupling components are conductively connected with the device/devices to be connected so that the equipotential bonding is not impeded by the paint or coat applied. In addition, make sure that the marking of the coupling remains legible. Painting or coating of the spider is generally not admitted.

7 Disposal

In respect of environmental protection we would ask you to dispose of the packaging resp. products on termination of their service life in accordance with the legal regulations and standards that apply.

•

Metal

Any metal components have to be cleaned and disposed of by scrap metal.

•

Nylon materials

Nylon materials have to be collected and disposed of by a waste disposal company.

8 Maintenance and service

ROTEX ® is a low-maintenance coupling. We recommend to perform a visual inspection on the coupling at least once a year . Please pay special attention to the condition of the coupling spiders.

•

Since the flexible machine bearings of the driving and driven side settle during the course of load, inspect the alignment of the coupling and re-align the coupling, if necessary.

•

The coupling components have to be inspected for damages.

•

The screw connections have to be visually inspected.

Having started up the coupling the tightening torques of the screws have to be inspected

! during the usual inspection intervals.

With the use in potentially explosive atmospheres observe chapter 10.2 "Inspection intervals for couplings in potentially explosive atmospheres".

9 Spares inventory, customer service addresses

We recommend to store major spare parts on site to ensure the readiness for use of the machine in case if a coupling fails.

Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at www.ktr.com.

 KTR does not assume any liability or warranty for the use of spare parts and accessories which are not provided by KTR and for the damages which may incur as a result.

Equipment category Inspection intervals

No gases and vapours of explosion group IIC

Gases and vapours of explosion group IIC

For couplings operated in zone 2 or zone 22 the inspection and maintenance intervals of the usual operating/assembly instructions for standard operation apply. During the standard operation which has to be taken as a basis of the ignition risk analysis the couplings are free from any ignition source. For gases, vapours and dusts generated the permissible glow and ignition temperatures specified in chapter 10.1 have to be considered and observed.

An inspection of the torsional backlash and a visual inspection of the flexible spider/DZ elements must be performed after 3,000 operating hours for the first time, at the latest after 6 months after start-up of the coupling.

If you note insignificant or no wear on the spider/DZ elements upon this initial inspection, further inspections can each be performed after 6,000 operating hours or at the latest after 18 months, provided that the operating parameters remain the same.

If you note significant wear during the initial inspection so that it would be recommendable to replace the spider/DZ elements, find out the cause according to the table „Breakdowns“, if possible.

The maintenance intervals must be adjusted to the modified operating parameters without fail.

An inspection of the torsional backlash and a visual inspection of the flexible spider/DZ elements must be performed after 2,000 operating hours for the first time, at the latest after 3 months after start-up of the coupling.

If you note insignificant or no wear on the spider/DZ elements upon this initial inspection, further inspections can each be performed after 4,000 operating hours or at the latest after 12 months, provided that the operating parameters remain the same.

The maintenance intervals must be adjusted to the modified operating parameters without fail.

Hubs, clamping hubs or similar types without feather keyways may be used in category 3 only and are marked with category 3 accordingly.

10.3 Standard values of wear

potentially explosive atmospheres

In case of backlash > X mm, the flexible spider/DZ elements must be replaced.

The general condition of the coupling can both be monitored at standstill and during operation. If the coupling is tested during operation, the operator must ensure an appropriate and proven test procedure (e. g. stroboscopic lamp, high-speed camera, etc.) which is definitely comparable to testing at standstill. Should any distinctive features arise, testing must be performed with the machine at standstill.

Reaching the limits for replacing depends on the operating conditions and the existing operating parameters.

In order to ensure a long service life of the coupling and avoid risks with the use in

! potentially explosive atmospheres, the shaft ends must be accurately aligned.

Please absolutely observe the displacement figures indicated (see table 11 to 13). If the figures are exceeded, the coupling will be damaged.
