OPERATING MANUAL
VERSION 01/2013 ORDER NUMBER DOC 2335747
Compressed air connection:
The compressed air supply must be properly dimensioned.
Connect the pump's compressed air connection to the pressure distribution network.
The connection must be carried out on the pump's tting. Do not replace the original
connection.
Use a pipe with a suitable diameter for the connection.
Always mount an air cut-o valve and an air processing unit ( lter/regulator unit).
The pressure must not exceed the maximum value indicated on the type 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 be run with non-lubricated air.
Air pressure quality: 5.5.4 = 40 μm / +7 / 5 mg/m³
Reversing valve:
The pump's reversing valve does not need any lubrication.
Safety valve:
The PM500 models are equipped with a safety valve that opens when the maximum
allowed value of compressed air supply is exceeded.
Non-return valve:
If the pump has been installed on a higher level than the liquid to be pumped, it is
recommended that a non-return 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 vacuum
produced by the pump.
The suction and material hoses and pipes must have a cross-section proportional to the
ow rate and the viscosity of the pumped uid. Avoid long and winding pipes, especially
during suctioning.
