CAUTION
Use only suitable and technically certified lifting gear to lift the pump. Only use
load suspension devices with sufficient carrying power.
4. Description
The plastic pumps of series BADU 90 have been designed to circulate pool
water in combination with a corresponding filter unit. The parts in contact with
the transported medium are mostly of glass fibre reinforced polypropylene PP
GF 30 and thus possess excellent corrosion resistance against the pool water
and the usual chemicals for treatment of the pool water. The pump housing
does not contain any inserts, therefore it can easily be recycled.
The motor shaft also serves as the pump shaft on which the impeller is moun-
ted. The seal for the shaft is a bellows-type mechanical seal arranged on a
plastic impeller hub. This guarantees a positive electrical separation between
the pool water and the electric motor. Because of the pumpʼs close coupled de-
sign, a minimum of space is required. The pumps are driven by three phase
motors. Integrated in the pump housing is a strainer basket (143), which keeps
coarse impurities from the pumpʼs interior.
5. Placement / Installation
5.1
CAUTION
The pump is equipped with a motor protection type IP X4. When installed out
side we recommend providing some protection against the rain. This will increa-
se the longevity of your pump. When installed in a closed room, like for exam-
ple in a plant room, in a cellar or in a pump pit a sufficiently dimensioned drai-
nage must be foreseen. The size of the floor drain depends on the size of the
pool, as well as on the circulation flow rate and on possible leakages within the
circulation system. At the installation site effective ventilation must be provided
for in order to prevent condensation and also to ensure sufficient cooling of the
pump motor and of other relevant appliances like control cabinets and control
units. The environmental temperature must not exceed 40°C.
Assembly and installation of the pump must be done in accordance with the re-
levant regulations e.g. DIN 4109, in order to reduce structure-borne noise and
air-borne noise. To do so the pump can be installed on a socle with cork layers
or for example foamed material (with the corresponding hardness). Pipes must
be mounted free of tension, if necessary they have to be arranged elastically. If
required, pipe compensators must be installed.
During installation, make sure that there is enough space available to permit
subsequent disassembly of the motor unit in the direction of the motor fan (mi-
nimum 120 mm) and the strainer basket (143) towards above (minimum 300
mm), see directions in the dimensional drawing. Fastening the pump to the
foundation should be effected exclusively by means of bolts, threads (or do-
wels) in order to avoid blocking the removal of the motor unit.
