operating instructions - Rusch-Pumpen Fabrik GmbH

pump while smaller particles cause continuous wear to an extent that
depends on their size, hardness, geometry, and volumetric concentration.
In order to protect the pump against such particles, a fine mesh suction
filter of the largest possible size should be provided. The dimensions of
the filter should be designed such that, with clean filter elements, the
pressure loss does not exceed 1 mWC. The mesh size should be 0.1 to
0.5 mm.
4.3.4 CONSERVATION AND STORAGE
If the pump is not used for long periods, is put into storage or, together
with the pipework, is filled with liquid and put under pressure to test for
leaks, it must be suitably conserved to prevent rust formation.
Attention! If conservation is not expressly specified at the time
of ordering, it must be carried out subsequently.
