Start ‐ up

Before initial start ‐ up, the pump must be filled with liquid one time so that the
suction stage can create a vacuum. During subsequent shutdown, enough residual
liquid always remains in the pump so that a restart can take place without refilling.

The centrifugal pump is sealed with a mechanical seal on the shaft. This dynamic seal
may not run dry and must always be lubricated with liquid. This seal was placed after
the centrifugal pump stages and after the suction stage. For this arrangement, the
seal is always protected against a dry run even during priming when there is very
little liquid in the pump.

The suction line (max. 3m) should be as short as possible and guided vertically
(always rising!) out of the suction tank. This is decisive for a good suction function of
the pump. Suction lifts up to max. 2m are possible.

When priming, air is first drawn into the inside of the pump. A ventilation option
must be provided. The pressure line must be open (without non ‐ return valve) or a
small ventilation line should be installed.
