PROBLEM

CAUSE

SOLUTION

Motor runs but pump

does not inject or

dosing is lower than

nominal

- Pump not primed

- Prime the pump by opening the priming

valve or filling the head with the liquid to

be injected

- Dirty or damaged suction or

discharge valve

- Clean or change valves

- Dirty suction filter

- Clean filter

- Air enters the suction pipe

- Check tightness of connection points

- Cavitation in suction

- Increase pipe diameter.

- Reduce the suction pipe length.

- Reduce speed by using a variator.

- Use a less viscous liquid.

Pump drips liquid

from hole in bottom of

cylinder

- Damaged diaphragm

- Change diaphragm
