In pumps with split manifold, DO NOT USE TWO
FLUIDS WITH DIFFERENT VISCOSITIES as STALL,
PREMATURE DIAPHRAGM AND PNEUMATIC CIRCUIT
WEAR may occur.
WARNING
8. Only the air supply must be used to stop the pump, by closing the three-way valve
to discharge any residual pressure from the pump’s pneumatic circuit.
After two hours of operation, and after stopping the pump correctly, check that all
of the bolts are tight.
Besides being damaging for the pump, cavitation is dangerous in a potentially ex-
plosive atmophere: You must ascertain that the pump has been sized correctly. In
case of doubt, please contact PIUSI.
never stop the pump when it is running and/or when
the pneumatic circuit is under pressure by closing
the intake and/or delivery valves on the fluid circuit:
DANGER OF PUMP STALLING AND PREMATURE
WEAR AND/OR BREAKAGE OF THE DIAPHRAGM.
ascertain that no anomalous noises occur during
operation. If so, stop the pump immediately.
In the case of high viscosity fluids, do not use un-
dersized filters or piping, especially on the intake
side. Furthermore, you must decrease the pump
speed by choking the volume of air whilst leaving
pressure unchanged.
ascertain that the fluid at the delivery side does not
contain gas. Otherwise stop the pump immediately.
