OPERATING MANUAL
VERSION 12/2012 ORDER NUMBER DOC 2330426
Air inlet connection:
The driving air pipe must be properly dimensioned.
Connect the compressed air supply to the pump to the pressure distribution network.
The connection must be carried out on the tting on the pump. Do not replace the
original connection.
Use a pipe with a suitable diameter for the connection.
Always install an air cuto valve and an air processing unit ( lter/regulator unit).
The pressure must not exceed the maximum value indicated on the plate.
Air pressure quality:
The pneumatic motor must be supplied with clean and dry industrial air. Make sure e cient
lter and condensation separation systems are installed on the air line.
The pump can run with non-lubricated air.
Air pressure quality: 5.5.4 = 40 μm / +7 / 5 mg/m³
Reversing valve:
The reversing valve of the pump is lubricated at the factory and does not need any
lubrication.
Safety valve:
The ZIP models are equipped with an internal safety valve that opens when the maximum
allowed value of air pressure supply is exceeded.
Back-pressure valve:
If the pump has been installed on a higher level than the liquid to be pumped, it is
recommended that a back-pressure valve be provided at the lower end of the suction pipe.
All hoses and components connected to the supply line must be able to operate at the
pump’s maximum pressure with the pump working at a pulsating pressure.
All items connected to the suction manifold must not get crushed as a result of the
depression produced by the pump.
The suction and delivery hoses and pipes must have a cross-section proportionate to the
ow rate and the viscosity of the pumped uid. Avoid long and winding pipes, especially
in the suction.
