Series AS 0530-0841

Sulzer submersible wastewater pump AS 0530-0841

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 12056 (AS 0530 – 0841), EN 12050-2 (AS 0530 – 0641), and EN 12050-1 (AS 0830 – 0841).

Applications

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 propor- tions of solid or fibrous matter.
  • Maximum allowable temperature of the medium is 40 °C, or 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 Ex d IIB T4 and FM international standards. Consult Sulzer Pumps 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

AS 0530: G 2″ internal thread (DN 50)
AS 0630 to 0641: radial slot DN 65 flange
AS 0830, 0831, 0840 & 0841: radial slot 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).

Features

  • Hydraulic design with Contrablock system or vortex impellers.
  • High reliability even under long term operating conditions.
  • For wastewater and sewage 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.
