Operation
Initial Operation
Pump Priming
The pump takes in (sucks) the material on up-stroke
and discharges it under pressure to the pump outlet on
up- and down-stroke. As the pump inlet is not yet filled
with material, the pump must cycle slowly in the
beginning in order to prime.
• Couple air connecting hose for pump drive by air
quick-coupling to airmotor.
• Slowly regulate the secondary air pressure (air
pressure operating the airmotor) > ‘Zero’ using the
air pressure regulator.
− When pump drive starts to operate do not increase
air pressure to pump.
If air pressure is too high and pump fails to prime,
immediately reduce air pressure to pump step by
step and allow pump to cycle slowly.
• Allow pump to cycle very slowly until pumping
material fills out pump and lines.
− If pump stalls (because of friction) before all material
lines are filled, cautiously increase air pressure.
• Close outlet of material line when all air is pushed
out and material flows without air pockets.
The pump should stalI against pressure when material
outlet(s) are closed and the system is properly filled with
material.
After priming and filling procedure is completed, the
setting of the required pressure follows. On adjusting
the air operating pressure by air pressure regulator, the
working pressure rating of the air and material line
system components must be regarded.
According to the pressure ratio of the pump, the air
pressure will be transformed to a 50-times higher fluid
pressure.

manufacturer / supplier of the complete material
dispensing system.
⇒ See 3.
3 ‘Technical Data’ of pump.
On adjusting the air operating pressure observe:
• Always use the lowest pressure to achieve the
desired results and never exceed the permissible
max. working pressure.
• Reduce pressure
− if pump runs evenly but continuously exceeds
120 cycles per minute.
− if pump accelerates or cycles erratically, not allowing
the material to follow and to be taken in by the pump.
In case of malfunction see checklist and notes in
section ‘Trouble Shooting’.
If applicable: During initial operation check operation of
low level control (pump shut-off device) in time when
material in the container is running low. Re-adjust level
control if device should not operate just in time.
CAUTION
Do not allow pump to operate when out
of material. Immediately shut off air to
pump!
5.
3 Standard operation.
Operate pump / equipment by qualified, instructed
personnel only.
Warning
Do not exceed the stated working
pressure of the airmotor/pump and
other system components.
Hands away from lower part of the
pump (material inlet) and all outlets for
the material.
Never attempt to disassemble pump/
equipment while system (pump and
system components) is pressurized.
Shut pump off in case of malfunction/damages or
changes in the behaviour of the pump during operation.
CAUTION
When using pump for applications, for example for filling
purposes, which require longer periods of time of
continuous pump operation, do not exceed pump cycle
speed of 75 cycles/min.
Shut pump immediately off when container is empty
before pump is out of material and ‘run-away’ condition
occurs.
Operation
Prior to operation (at least 1 x per working shift):
• Check pump / equipment visually for damages and
abnormal shape.
The operating of pump / equipment depends on the
individual design of the material dispensing system.
⇒ See Operating and Safety Instructions of the
manufacturer / supplier of the complete material
dispensing system.
Pump / airmotor are normally under pressure during the
operation mode. The pump starts when the material
outlet (shut-off valve, flow gun, etc.) is opened and
discharges the material. The material flows under
pressure from the outlet opened.
• Always disconnect air coupler from pump when
pump sits idle for long periods of time. Also perform
pressure relief procedure when equipment is shut
down. Depressurize material system by opening end
of line shut-off valve/flow gun and drain material into
a collecting can.
• In case of malfunction during operation, shut pump
off.
⇒ See checklist and notes in section ‘Trouble
Shooting’.
• When container is empty, immediately shut pump
off. Do not allow ‘run-away’ of pump!
− Disconnect air connecting hose from pump drive.
− Change material reservoir or refill.
Procedure and handling depend on the individual
design of the equipment.
− If using a follower plate, take care that follower is
seated onto the pumping material and all air is
expelled underneath the follower plate.
− Reduce air operating pressure to pump by air
pressure regulator before coupling air connecting
hose to pump drive.
