ABS submersible sewage pump AFP 0831-2046

1 ABS submersible sewage pump AFP 0831-2046 Text var Type testedand monitoredRobust, reliable submersible pumps from to 30 kW for pump-ing wastewater and sewage from buildings and sites in private, commercial, industrial and municipal areas in accordance with EN 12050-1. Available as standard AFP or as higher specification AFP(K).ApplicationsAFP submersible pumps have been designed for the economic and reliable pumping of clear or wastewater, gaseous liquids, and for sewage and sludge, in fixed or portable applications.* For fixed, wet well applications the AFP is pedestal mounted.

2 Us-ing a self-sealing coupling system the pump seals automatically on the pedestal when lowered by guide rail into position.* Dry well applications have the option of horizontal or vertical installation.* With vortex hydraulics the AFP is particularly suitable for sew-age, abrasive matter, and fluids containing stringy materials that tend to rope .* The Contrablock hydraulic system offers higher efficiency and is suitable for larger proportions of solid or fibrous water-pressure-tight, encapsulated, fully flood-proof motor and the pump section form a compact, robust, modular construc-tion.

3 Maximum allowable temperature of the medium for con-tinuous operation is 40 C (information on applications at other temperatures available on request).Available in explosion-proof versions in accordance with interna-tional standards EExd II BT4, FM and : Free-circulation cooling by the (K): Closed loop cooling system with circulation of glycol and water which has no contact with the sewage being pumped. This optimises heat exchange and avoids the danger of blockage of the cooling system with sewage installation is possible without cooling system, for intermittent use only and subject to strict stainless steel motor shaft is supported in lubricated-for-life ball sealingBetween the motor and hydraulic section is by means of a high quality, silicon carbide, double mechanical seal.

4 Standard AFP has a single mechanical seal and upper lip seal. AFP(K) has the option of double mechanical seals or a seal cartridge. The seal cartridge combines both mechanical seals into a complete, easy-to-replace unit (not available with ME motor). All seals are independent of rotation direction and resistant to temperature 80, 100, 150 and 200 DIN monitoringTCS (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 monitoringDI system consisting of a sensor in the motor and oil chambers which signals an inspection alert if there is leakage at the shaft seals (not in oil chamber on Ex version).
