Surface Pumps; Placement And Foundation - Lorentz PSk2-7 Manuel D'installation Et De Fonctionnement

9.3 Surface Pumps

9.3.1 Placement and Foundation

Rain and weather protection – The pump is equipped
with IPX4-type motor protection. If it is installed outside, the
pump must be protected from rain and direct sunlight. This
will increase the durability of your pump.
CAUTION – CS-F and CS-G pumps must not
be submerged in water or subjected to
rain or dripping water.
CAUTION – If the pump is installed in a
humid area, effective ventilation and
aeration must be provided in order to
prevent condensation.
CAUTION – When installing in very small
installation spaces the natural cooling
may be insufficient. Carefully consider the
ventilation in order not to exceed the
maximum ambient temperature.
CAUTION – The pump might heat up in
operation. The pump must not be installed
on combustible surfaces. Strong
incombustible surfaces should be used,
e.g. concrete or stone surfaces.

Pump Installation
Foundation – An arrow on the pump base shows the
direction of the flow of the fluid through the pump. It is
recommended to install the pump on a concrete foundation.
The foundation must be level and should have min. approx.
1.5 times the weight of the pump to absorb vibration, shock
and strain.
Connecting the pump to the foundation – Fastening
the pump to the foundation should be done exclusively by
means of properly sized bolts or threads (dowels) in order to
avoid any movement of the pump unit.
CAUTION – The pump must be mounted
vertically.
CS-G pumps are supplied along with a base plate that has
to be mounted to the bottom of the pump. Use only the
screws that are supplied with this base plate, do not install
this pump without this base plate.
Space – During installation, make sure that there is enough
space available to permit subsequent disassembly of the
motor unit. It is recommended to have at least 1m of free
space above the pump.
