US 73–US 253

Submersible pumps for commercial applications

Areas of application: Heavily contaminated and fibre-bearing waste water with coarse impurities
Made in Germany

  • 30 mm free passage
    (US 73-153)
  • 40 mm free passage
    (US 253)
  • Safe to run dry
  • Controllable oil chamber
  • SiC mechanical seal independent of sense of rotation
  • Replaceable moisture sealed cable inlet

The centrifugal submersible drainage pumps US 73-253 are suitable for dealing with contaminated water and capable of handling solids up to 30 and 40 mm particle size without stones. Fibrous waste water, as found in laundries or automatic launderettes and waste water from domestic dishwashers and washing machines can be handled by this pump range. For hot water in the industrial and commercial market we recommend the US 73 and US 103 HE/HES.
This range of pumps is suitable for stationary use. For easy removal of the pumps from deep sumps we recommend the use of our guide rail systems which provide ease of maintenance and inspection.
For automatic monitoring of the oil chamber a seal leak control can be connected.
The cable length is 10 m. The 3-phase pumps with built-in level control (US 153 DS and US 253 DS) have a CEE-plug with phase inverter.
The sewage pumps are tested by the German Institute for Construction Engineering and correspond to the valid construction and test principles.

Scope of supply

Pump according to DIN EN 12050 ready for connection with 10 m cable. US 73 and US 103 with safety plug (1-phase) or CEE-Plug (3-phase).
US 153 and 253: Pumps without level control with free lead end. Pump with level control with CEE-motor protective plug and phase inverter (3-phase) or safety-plug (1-phase).
