Never use force when dismantling and reassembling the pump set.

7.2 Servicing/inspection

7.2.1 Supervision of operation

DANGER

Incorrectly serviced shaft seal

Fire hazard!

Hot fluids escaping!

Damage to the pump set!

▷

Regularly service the shaft seal.

CAUTION

Increased wear due to dry running

Damage to the pump set!

▷

Never operate the pump set without liquid fill.

▷

Never close the shut-off element in the suction line and/or supply line during
pump operation.

CAUTION

Impermissibly high temperature of fluid handled

Damage to the pump!

▷

Prolonged operation against a closed shut-off element is not permitted
(heating up of the fluid).

▷

Observe the temperature limits in the data sheet and in the section on
operating limits.

(

Section 6.2, Page 25)

While the pump is in operation, observe and check the following:

▪

The pump must run quietly and free from vibrations at all times.

▪

Check the shaft seal.

(

Section 6.1.5, Page 25)

▪

Check the static seals for leakage.

▪

Monitor the stand-by pump.
To make sure that the stand-by pumps are ready for operation, start them up
once a week.

7.2.2 Inspection work

DANGER

Excessive temperatures caused by friction, impact sparking or frictional sparking

Fire hazard!

Damage to the pump set!

▷

Regularly check the cover plates, plastic components and other guards of
rotating parts for deformation and sufficient distance from rotating parts.
