∑ (F V )
(F Vmax )
∑ (F V ), ∑ (F H ) and ∑ (M t ) are the sums of the absolute
amounts of the corresponding loads applied to the
supports. Neither the direction of the loads nor their
distribution across the supports are taken into account
in these sums.

5 Siting/Installation

5.1 Installation
– Installation only after all welding/soldering on the
pipework is completed and the pipe system has
been flushed out. Foreign matter and impurities
may cause damage to the pump.
– Standard design pumps must be installed in a
frost- and dustfree, well-ventilated and non po-
tential explosive environment.
— Mount the pump in an easily accessible position
in order to facilitate later inspections or ex-
change.

– Provide and place a hook or eyebolt of respec-
tive load bearing capacity (total weight of pump:
see catalogue/data sheet) vertically above the
pump, suitable for taking lifting gear or other me-
chanical aids capable of handling the pump for
maintenance or repairs.
– The pump must be carefully handled by means
of authorized lifting gear (see chap. 3).
– Minimum axial clearance between a wall and the
motor fan cover: clearance required for removal
to min. 200 mm + l of fan cover.
– Isolating valves must be provided and installed
on suction and discharge ports in order to avoid
