Submersible wastewater pump type ABS AS

Reliable pumps for wastewater removal

The AS range are robust, reliable submersible pumps from 1 to 3 kW for pumping wastewater and sewage from buildings and sites. The pumps have water pressure-tight, encapsulated, fully flood-proof motors in standard and explosion-proof versions.

Submersible wastewater pump type ABS AS 0840
Main benefits
  • Hydraulics with Contrablock system or vortex impellers for blockage free operation
  • Suitable for portable as well as in stationary installations 
  • 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
  • Available in three discharge sizes: DN 50 (G2"), DN 65 (G2½"), and DN 80 (G3")
  • Free-standing on legs or pedestal-mounted
