Oil Change
The first oil change must be performed after 500 hours. Unscrew oil load plug and let
exhaust oil flow outside pump. It’s suggested to wash inside the pump with
petroleum. After refilling, turn on the motor without pumping fluid for some minutes.
During this operation, check oil level and refill if necessary. The oil requested is SAE
30W40 or similar.
Troubleshooting
Troubleshooting
The motor doesn’t start:
Check if power cord isn’t damaged and then verify if
electrical connection respects motor data on label.
The motor stops suddenly:
Probably thermal protection switch has disconnected
the motor. Wait for some minutes, then restart. Check if power has breaked and if
the motor starts slowly. Is the bypass valve opened ?
Motor overheating:
Check cooling fan good working, starting conditions and oil
level. If necessary, contact our technical helpdesk.
The pump doesn’t turn:
Check if the bypass valve is open. Check starting
capacitor. If necessary, contact our technical helpdesk.
The pump cannot reach requested pressure:
Verify for losses on plant, close
pressure regulation valve. If necessary, clean inlet filter. In a second time, check for
valve wearout or dirty. If you need one, use only original spare parts.
Low flow rate:
Check for dirty on inlet filter or for small section on suction
hose, that can cause losses. If the pump is also noisy, check oil level. If necessary,
contact our technical helpdesk.
Pressure oscillation:
Check for air inside the pump. To eliminate this air, work for a
while with outlet opened. Be careful, water jet can be dangerous for electrical and
mechanical risks. Check, with motor turned off, that air accumulator is loaded at right
pressure. In a second time, check valve wearout or dirty inside. If necessary, contact
our technical helpdesk.
White oil or oil from outlet:
Diaphragm broken. Change diaphragm.
