WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐

ries.
Please ensure when handling hazardous sub‐

stances that you have read the latest safety data

sheets provided by the manufacture of the haz‐

ardous substance. The actions required are

described in the safety data sheet. Check the

safety data sheet regularly and replace, if neces‐

sary, as the hazard potential of a substance can be

re-evaluated at any time based on new findings.
The system operator is responsible for ensuring

that these safety data sheets are available and that

they are kept up to date, as well as for producing

an associated hazard assessment for the worksta‐

tions affected.

Before all work
Before all work on the double diaphragm pump,

disconnect the double diaphragm pump from the

compressed air supply and the feed and discharge

lines, vent and decontaminate. Always observe the

safety data sheet for the chemicals to be con‐

veyed.

8.1  Troubleshooting

The pump is not working.
Cause:

Recommended measure:

The outlet valve on the discharge side is not

open.

Open the discharge valve on the discharge side.

No air supply.

Switch on the compressor and open the air valve and the

air regulator.

The air pressure is too low.

Check the compressor and the configuration of the air

line.

Air is escaping from the connecting elements.

Check the connecting elements and the torque of the

screws.

The air lines or additional equipment are

blocked with foreign bodies.

Check and clean the air line.

The outlet opening (silencer) of the pump is

blocked with foreign bodies.

Check and clean the outlet opening and the silencer.

The liquid line is blocked with foreign bodies.

Check and clean the liquid line.

The pump is blocked with foreign bodies.

Remove, check and clean the pump housing.
