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. * The 2-inch version is especially suitable for pumping wastewater from underground garages.
Type tested and monitored * With vortex hydraulics the AS is particularly suitable for fluids containing fibrous or abrasive matter and for sewage. 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 port- able units. * The Contrablock hydraulic system is suitable for larger propor-tions 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 Bearings Single-phase 220-240 V and three-phase 400 V, 50 Hz, 2-pole (2900 r/min) and 4-pole (1450 r/min). Professional insulation class F; protection type IP 68. Ex protection to EExdIIBT4 and FM international standards. Consult ABS for Ex usage with frequency inverters. The stainless steel motor shaft is supported in lubricated-for-life ball bearings. Shaft sealing Discharge 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. AS 0530: G 2” internal thread (DN 50) AS 0630 to 0641: DN 65 flange 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, 0630, 0631, 0830: vortex, open, recessed four-vane impeller. AS 0641, 0840: Contrablock, open single-vane impeller with spiral bottom plate.
