Before connecting the pump, take the yellow blind plugs
out of air inlet which is located on the top of the damper
head [16]. 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 oil-free, 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 changing operating
conditions.

• Before putting the pulsation damper into operation as well as after some hours of
operating, the housing bolts [10] have to be tightened carefully, 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 page 5.
Disassembly instructions
Unscrew housing bolts [10] carefully. After that, all parts can be removed. Screw the diaphragm [14] off the
actuator shaft [13]. A re-assembly of used piston rings [17] is impossible; they have to be replaced including
the O-rings underneath. To assemble new piston rings [17] 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.
