Overview

RUHRPUMPEN'S SUBMERSIBLE PUMP TYPES

A standardized submersible motor is combined with different pump casings and impellers to build the different pump types:

  • PVT with axial propeller for high flow and low heads
  • TRT with semi-axial impeller for medium flow and high heads
  • LKT with three-channel impeller for small flow and low heads
  • STT with non-clogging and nonstringing two-channel impeller
INSTALLATION

The pump is placed via an O-Ring and without any fixing devices on a machined, conical supporting and centring ring. By its own weight the pump is emplaced self-centring and resistant against tilting and distortion.

The installation has to be performed in a way that the intake of the pump is submerged to a certain depth. The necessary minimum submergence is shown in the pump curve as Hü.

ACCESSORIES
  • PES-lifting rope for pump and cable with rubber elements to bind together cable and lifting rope
  • Monitoring system Thycon VR-T for evaluation of all sensors
CHARACTERISTICS
  • Stable lifting handle where the lifting device is fixed on
  • Strain relief for the cable inlet
  • Water tight, replaceable cable inlet
  • Water tight encapsulated terminal housing with humidity probe
  • Temperature probes in the windings (3x PTC)
  • Dry running three-phase induction motor with squirrel cage rotor
  • Temperature monitoring of the lower bearings via PT100
  • Humidity probe in the oil chamber for early indication of inspection based on the water to oil ratio
  • Collection chamber with a float switch located underneath the lower bearings
  • Shaft sealing by two mechanical seals in tandem arrangement

PVT - Submersible Axial Propeller Pump

The Ruhrpumpen Type PVT is a vertical submersible pump with axial propeller suitable for high flow and low head applications. It can pump clean, raw, river and rain water, as well as pre-cleaned waste water and activated sludge.

LKT - Submersible Three-Channel Pump

The Ruhrpumpen Type LKT is a vertical submersible pump with a three-channel impeller. It is suitable to pump activated sludge as well as mixed, rain and raw water with an upstream screen.

STT - Submersible Sewage Pump

The Ruhrpumpen Type STT is a vertical submersible pump with non-clogging and nonstringing two-channel impeller in pot design for stationary dry or wet well installation. It is suitable for pumping sewage with coarse solid matter and fibrous content without upstream screen.
