The pump can be completely submerged in the
fluid.
The electric motor is protected against the pump
chamber by a rotary shaft seal to seal the motor
against the oil chamber and a mechanical seal
to seal the oil chamber against the fluid. The
mechanical seal chamber is filled with medical
white oil so that the mechanical seal is lubricat-
ed and cooled during a dry run. A further rotary
shaft seal protects the mechanical seal facing
the fluid. The motor is cooled by the surrounding
fluid.
The pump is installed on the floor of a shaft. For
a stationary installation, it is bolted to a fixed
24
pressure pipe or for a transportable installation, it
is connected to a hose connection.
The pumps are commissioned by plugging in the
protective contact plug.
They operate automatically, when the float
switch switches the pump on from a certain
water level "h" (Fig. 2) and switches it off at a
minimum water level "h1".
The motors are equipped with thermal motor
protection, which switches off the motor auto-
matically if it overheats and switches it on again
when it has cooled down. The condenser is inte-
grated in the single-phase motor.
Version with whirl system (TWISTER-Function)
For waste water with precipitating and float-
ing particles, the submersible pump has been
equipped with a whirl system at the suction
strainer. Precipitating particles are continuously
whirled up in the suction area of the pump and
pumped off with the water. Therefore, mud
accumulation in the pump shaft, with problem-
atic consequences such as clogging of the pump
and odour formation, is largely prevented.
If the removal of the waste water does not allow
any interruption, a second pump (automatic
standby pump), together with the necessary
switchgear (accessory), increases the operating
reliability if the 1st pump develops a fault.

7. Installation and electrical connection

DANGER! Risk of fatal injury!
Incorrect installation and improper electrical.
• The installation and electrical connections should
only be done by properly skilled staff and in
compliance with the applicable regulations!
• Follow all accident prevention regulations!
7.1 Installation
The pump is designed for stationary or trans-
portable installation.
CAUTION! Danger of property damage!
Danger of damage due to incorrect handling.
Only suspend the pump by the strap with the aid
or a chain or rope, never by the electrical or float
switch cable or the pipe/hose connection.
The installation site or shaft for the pump must
be free of frost.
The shaft must be cleared of coarse material
such as rubble before setting up and starting the
pump. The quality of the shaft must guarantee
the unhindered mobility of the float switch.
