The pump can be completely submerged in the
fluid.
The submersible pump housing consists of stain-
less steel.
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 lubricated
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 pres-
sure 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 pro-
tection, which switches off the motor automati-
cally if it overheats and switches it on again when
it has cooled down. The condenser is integrated in
the single-phase motor.
Version with whirl system (TWISTER function)
For waste water with precipitating and floating
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 accu-
mulation in the pump shaft, with problematic
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.
