6. 

Start-up and operation

Before starting the pump, dismantle and clean the suction pipe. 

 

Any foreign material in the pump should be removed.

6.1 

Checking the pump for foreign material

Remove the pump body as described below. The sectional drawing 

(page 3) is to be used for reference purposes.

1. 

Disconnect the power supply.

2. 

Remove the pump body (items 1a, 1b) by unscrewing the clamp ring 

(item 9a) or body screws, and carefully extract from the body.

3. 

Turn the impeller (item 4) to ensure that there is no foreign material 

behind it.

4. 

Remove any foreign material from inside the pump.

5. 

When the pump body is clean and free of foreign material, reassemble 

the pump.

Mount the pump body as described below:

6. 

Check that the locating pin (item 8), which is installed in the top of the 

back plate, fits with the detent in the pump body and carefully (to 

avoid damage to the O-ring) press the pump body (item 1a, 1b) 

in so it covers the O-ring (item 6). Then fasten with the clamp ring 

(item 9a) or body screws and apply the correct tightening torque.

M10: 

max. 35 Nm (25 ft-lb)

7. 

Check that the pipe unions have been tightened properly and that the 

pipe supports have been fitted.

To facilitate the fitting of the front cover and pump housing, we 

recommend that the O-ring is lubricated with a thin layer of food-

friendly, acid-free grease or soap.
