Submersible Wastewater Pump Type ABS AS

The AS 0530-0841 range features robust, reliable submersible pumps from 1 to 3 kW for pumping clear water, wastewater, and sewage from buildings and sites in both domestic and commercial areas.


  • Water pressure-tight, encapsulated, fully flood-proof motors in standard or explosion-proof versions
  • Hydraulics with Contrablock system or vortex impellers for blockage free operation
  • Suitable for portable as well as in stationary installations
  • Available in three discharge sizes: DN 50 (G2"), DN 65 (G2½"), and DN 80 (G3")

Main benefits

  • Hydraulic design with Contrablock system or vortex impellers
  • Two- and four-pole design
  • Passage of solids from 40 to 80 mm
  • Standard 10 m cable
  • Automatic coupling system
  • Available as standard or Ex-version

Main applications

  • Sewage and wastewater containing fecal matter
  • Two-inch version especially suitable for pumping wastewater from underground garages
  • Vortex hydraulics
  • AS particularly suitable for fluids containing fibrous or abrasive matter
  • Contrablock hydraulic system for larger proportions of solid or fibrous matter

Main design features

  • Thermo Control System (TCS) with thermal sensors in the stator in order to switch the pump off in the event of overheating and switch it on automatically after cooling down (option on standard AS)
  • High-quality sealing unit using a silicon carbide mechanical seal between the motor and the hydraulic section, ensuring independent rotation direction and providing resistance to temperature shock
  • Oil-lubricated lip seal at motor side
  • Stainless steel rotor shaft supported in lubricated-for-life ball bearings
  • Ex protection to Ex d IIB T4 and FM international standards
  • Free-standing on legs or pedestal-mounted
