Operation

Filling and venting the pump

1.

Variant 1:

Ensure that the sealing chamber

A

is filled application-specifically and vented and sealing

chambers

B

and

C

are filled with PTFE grease, see "Lubricating the radial shaft seal", page 30.

Variant 2:

Ensure that the sealing chamber

B

is filled with quench liquid and that the filling levels are

observed in the quench tank, see "Refilling quench liquid", page 31. Ensure that the sealing
chamber

A

is filled application-specifically and vented and sealing chamber

C

is filled with PTFE

grease, see "Lubricating the radial shaft seal", page 30.

Variant 3:

Ensure that the circulation line for the quench liquid is opened and the sealing chamber B

is filled with quench liquid.
Ensure that the sealing chamber

A

is filled application-specifically and vented and sealing

chamber

C

is filled with PTFE grease, see "Lubricating the radial shaft seal", page 30.

2. Open the screw plug of the upper vent hole by a max. of two rotations, see Fig. 5, page 22, so that

air can escape during the filling process.

3. Open the suction-side shut-off device.

Through the inlet pressure the pump fills with pumped liquid.

4. After a short while, tighten the screw plug of the vent hole again, so that no pumped liquid can be

emitted.

Checking the direction of rotation

The direction of rotation is indicated by arrows on the pump. The direction of rotation of the motor speci-
fies the direction of rotation of the pump. That is to say, the fan impeller of the motor must rotate in the
direction in which the arrow on the pump is pointing to indicate direction of rotation.

□

Standard direction of rotation:Clockwise (viewed from the drive)

DANGER

Risk of death through emitted pumped liquid.
Pumped liquids can be hot, poisonous or caustic and can spray out under high pressure.

► Wear protective equipment during all the work. Ensure face protection.
► Collect the emitted pumped liquid safely and dispose of it in an environmentally compatible man-

ner.
