ABS AS 0530 to 0840 - Submersible Wastewater Pump

ABS Submersible Wastewater Pump AS 0530 - 0840 robust, reliable submersible pumps from 1 to 3 kW for pumping clear water, wastewater and sewage from buildings and sites in domestic and commercial areas in accordance with EN 12050-1.

Applications

The ABS AS submersible pumps have been designed for the economic and reliable pumping of wastewater and sewage, and can be used for fixed applications with ABS automatic coupling system or as portable units.
  • The 2-inch version is especially suitable for pumping wastewater from underground garages.
  • With vortex hydraulics the AS is particularly suitable for fluids containing fibrous or abrasive matter and for sewage.
  • The Contrablock hydraulic system is suitable for larger proportions of solid or fibrous matter.
  • Maximum allowable temperature of the medium for continuous operation is 40 °C, or if unit is submerged, short term to 60 °C (max. 5 minutes).

Construction

The water pressure-tight, encapsulated fully flood-proof motor and the pump section form a compact, robust, unit construction.

Motor

Single-phase 220-240 V and three-phase 400 V, 50 Hz, 2-pole (2900 r/min) and 4-pole (1450 r/min). Insulation class F; protection type IP 68. Ex protection to EExdIIBT4 and FM international standards. Consult ABS for Ex usage with frequency inverters.

Bearings

The stainless steel motor shaft is supported in lubricated-for-life ball bearings.

Shaft sealing

Between motor and hydraulic section by means of a high quality sealing unit using a silicon carbide mechanical seal, independent of direction of rotation and resistant to temperature shock. Seal at motor side is by oil lubricated lip seal.

Discharge

ABS AS 0530: G 2” internal thread (DN 50)
ABS AS 0630 to 0641: DN 65 flange
ABS AS 0830 & 0840: DN 80 flange

Temperature monitoring

TCS (Thermo-Control-System) with thermal sensors in the stator to switch off the pump in the case of overheating and switch on automatically after cooling down (option on standard AS).

Seal monitoring

DI system consisting of a sensor in the motor and oil chambers which signals an inspection alert if there is leakage at the shaft seals (option on standard AS; not in oil chamber on Ex version).

Hydraulics

AS 0530, AS 0630, AS 0631, AS 0830: vortex, open, recessed four-vane impeller.
AS 0641, AS 0840: Contrablock, open single-vane impeller with spiral bottom plate.

Features

  • Hydraulic design with Contrablock system or vortex impellers.
  • High reliability even under continuous operating conditions.
  • For wastewater, sewage and sludge containing solid or fibrous particles.
  • In standard or Ex-versions.
  • Option of automatic seal and temperature monitoring. Ex version with temperature monitoring as standard.
  • Available for transportable or fixed installation.
