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.

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
