Problem
Possible cause
Solution
The pump does not start
Feed air not sufficient
Check on the air supply line. Increase
the diameter of the feed hose
Outlet product line clogged
Clean. Disconnect the outlet hose of the
product, feed the pump at the minimum
pressure and verity if the pump starts
without the outlet hose
Dried product inside the pumping element
Disassemble the pumping group and
clean
Pneumatic motor blocked in the cycle
reversal position
• Reduce feed air pressure
• Manually reset the pneumatic motor
Parts failure of the pneumatic motor
Disassemble the motor and verify
accelerate working and no pressure
of the pump
There is no product
Add the product
The pump sucks air
Open the bleeder valve. For the ram
version, read the instructions contained
in the relevant manual
Feed air not sufficient
Increase feed air pressure
Gaskets of the pumping rod worn
Replace the lower gaskets
Suction valve worn or partially clogged
Disassemble the suction valve. Clean
and/or replace, if possible, the parts
worn
Outlet valve worn or partially clogged
Disassemble the outlet valve. Clean and/

and/or replace, if possible, the parts
worn
Outlet product line clogged
Clean. Disconnect the outlet hose of the

pressure and verity if delivery increases
without the outlet hose
The feed air pressure is too low
Increase air pressure
Waste of product from the wet cup
Upper gaskets worn
Tighten the packing nut. In case of
persistent waste of product, replace the
upper gaskets of the pumping element.
always close the compressed air supply and release the pressure in the plant before performing any check or
