9 Troubleshooting
Before working on the pump, ensure the power supply
is isolated.
➨ Motor Fails To Start
■ Pump is not connected to power supply.
■ Power supply is switched off.
■ The pressure in the delivery line from the pump is
too
high.
■ Pump is on “STANDBY“ → ON-/OFF button not
pressed.
■ External controlling is connected without input
signal.
➨ Pump Not Sucking Liquid In
■ Suction side of pump is not connected.
■ Liquid level in container is too low.
■ Hose connections are leaking.
■ A system valve is closed, or blocked.
■ The pump head is filled with gas. The gas
pressure after the pump can not be overcome
because of its compressibility in the working
chamber.
■ Diaphragm and/or valves are worn out or dirty.
➨ Flow Rate, Suction Height, or Pressure Height
Is
Insufficient.
■ The periphery installation contains components
(hoses, valves, filters, etc…) which create too
much
resistance.
■ Hose connectors are not tight.
■ Diaphragm or valves are worn out or are covered
in
dirt.
