6. Description and function
6.1 Description of the product (Fig. 1)
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 TSW with turbulator
For waste water with precipitating and float-
ing particles, the submersible pump has been
equipped with a turbulator 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 problematic consequences
such as clogging of the pump and odour forma-
tion, is largely prevented.
If the removal of the waste water does not
allow any interruption, a second pump (automat-
ic 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
connections can result in a risk of fatal injury.
• The installation and electrical connections
should only be done by properly skilled staff
and in compliance with the applicable regula-
tions!
• Follow all accident prevention regulations!
7.1 Installation
The pump is designed for stationary or transport-
able 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.
• Installation dimension / shaft dimensions (cf. Fig
2).
