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
(minimum 120 mm) and the strainer basket (143) towards above (minimum 230
mm), see directions in the dimensional drawing. Fastening the pump to the
foundation should be effected exclusively by means of bolts, threads or dowels
in order to avoid blocking the removal of the motor unit.
5.2 Installation
The pump must by no means be used as a supportive point for the pipes. The
pipes must be installed in such a way that no force or torque will be transmitted
to the pump (e.g. by distortion or thermal expansion). The pipes must have a
supportive fixation point directly in front of the pump so that its connection to
the pump is free of tension. This should be done by using suitable compensa-
tors.
If the pipe strength is exceeded, leaks can occur at the pump itself or at the
flange connections, which could result in vast losses of medium.
The suction pipe should be installed with a continuous upward angle and the
pressure pipe with a continuous downward angle in order to avoid air locks.
We recommend the installation of check valves and shut-off valves, according
to the type of pump or plant.
Expansions of the pipes caused by temperature must be compensated by ap-
propriate means. We recommend the installation of compensators between
pump and pipe.
Sudden closing of valves in pipes must be avoided. The resultant pressure im-
pacts caused by such shut offs often exceed the max. permissible housing
pressure of the pump by far. To absorb sudden pressure impacts, dampers or
expansion tanks must be installed.
CAUTION: ABS-glue-connections, glue socket (721), require a longer harde-
ning period. A minimum 12 hours must be admitted between the gluing and the
first start-up of the pump.
When using the inside thread, the connecting parts must be sealed with Teflon
tape only. Other sealing material can damage the thread or have only an insuf-
ficient sealing effect.
5.3
Mechanical / Hydraulic:
The pump must be installed in a horizontal position in dry condition. A shutoff
valve shall be provided in the suction- and pressure-pipe. It may be installed
either max. 3 m below (gravity feed) or above the liquid level (suction mode).
Thereby the geodetic head between liquid level and pump inlet must not ex-
ceed 3 m. The suction lift may be significantly reduced by flow resistance in the
suction line, if the pipes are very long and/or insufficiently dimensioned.
The suction pipe dimensions in the table are only valid for suction pipes not
longer than 5 m.
