J Possible cause

Remedy

✘ ✘

- Suction-side / discharge-side shut-off

element closed or set incorrectly

Open the suction-side shut-off element
Partially close the discharge-side shut-
off element to comply with the duty
point.

✘

- Wrong direction of rotation

Check the electrical connection of the
motor.

✘

✘ ✘

- Air ingress through suction line, check

valve in discharge line or at another
point between check valve and
discharge line

Check tightness of piping.
Check tightness of check valve.

✘

- Pump or suction line are not completely

vented or primed.

15)

Adjust the piping, so the vent
connections are positioned at the
highest point of the piping.

✘

- Discharge head too low

Increase speed.
Have the selection of pump or impeller
checked.

✘

- Incorrect speed

Measure the speed.
Check the supply voltage of the motor.

✘

- Pump or pipelines are not completely

vented or primed.

Prime and vent the pump as per the
instructions. (

Section 6.1.4, Page 34)

✘

✘ ✘

- Air enters through the sealing system.

Check the sealing system.
Check the sealing elements.

✘

- Impeller

Re-balance the impeller.
Replace the impeller.

✘

- Wear rings worn or fitted incorrectly.

Replace the wear rings.
