▪Only use the pump to handle the fluids specified in the data sheet or product

literature of the respective design variant.

▪Never operate the pump without the fluid to be handled.

▪Observe the minimum flow rates indicated in the data sheet or product literature

(to prevent overheating, bearing damage, etc).

▪Observe the maximum flow rates indicated in the data sheet or product

literature (to prevent overheating, mechanical seal damage, cavitation damage,

bearing damage, etc).

▪Do not throttle the flow rate on the suction side of the pump (to prevent

cavitation damage).

▪Consult the manufacturer about any use or mode of operation not described in

the data sheet or product literature.

Prevention of foreseeable misuse

▪Never open discharge-side shut-off elements further than permitted.

– The maximum flow rate specified in the data sheet or product literature

would be exceeded.

– Risk of cavitation damage

▪Never exceed the permissible operating limits specified in the data sheet or

product literature regarding pressure, temperature, etc.

▪Observe all safety information and instructions in this manual.

2.4 Personnel qualification and training

All personnel involved must be fully qualified to install, operate, maintain and

inspect the machinery this manual refers to.

The responsibilities, competence and supervision of all personnel involved in

required, the operator can commission the manufacturer/supplier to train the

personnel.

Training on the pump (set) must always be supervised by technical specialist

personnel.

2.5 Consequences and risks caused by non-compliance with these operating

instructions

▪Non-compliance with these operating instructions will lead to forfeiture of
