4 Product and accessory description

4.1 Pump description (fig. 1)
During operation, submersible motor-driven pump STS80/100 must be immersed in the flow
medium up to the uppermost surface of the motor (min. level inside shaft). It is driven by an
encased three-phase current motor made from stainless steel and which is impermeable to
pressurised water (1.4404) and is equipped with a non-chokable impeller (VORTEX). The non-
chokable impeller has short, radially-aligned blades which are only immersed in the liquid current
to approximately 1/3 of the pump housing height. This impeller is used for gas-charged fluids
and sewage containing long-fibre solids.
The STS80/100 immersed motor pump housing (pos. 1), impeller (pos. 2) and adapter (pos. 3) are
made from gray cast iron EN-JGL-250 (GG25). The flow medium enters from below through a
central opening and exits laterally via the DN 80 or DN 100 pressure-pipe connection.
The motor is sealed against the pump chamber using 2 seals:
- On the side containing the medium:
- On the motor:
So as to ensure both seals are lubricated and cooled, the space between the seals is filled with a
specific quantity of (biodegradable) white oil. This oil is poured in when the pump is assembled.
Filling levels: motors up to 3.8 kW
motors of 3.8 to 8.4 kW:
The pump is also equipped with a thermal winding contact (WSK) to prevent overloading.
Where the pump is assembled for stationary use, it is connected via a coupling base on the
outlet side. Where it is assembled for transport it is connected to a pipe connection on the outlet
side.
