ABS AFP range of robust, reliable submersible pumps from 1.3 to 30 kW for pumping waste water 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).
Applications
AFP 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. Using 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 sewage, 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 matter.
Construction
The water-pressure-tight, encapsulated, fully flood-proof motor and the pump section form a compact, robust, modular construction. Maximum allowable temperature of the medium for continuous operation is 40 °C (information on applications at other temperatures available on request). Available in explosion-proof versions in accordance with international standards EExd II BT4, FM and ATEX.
Cooling
AFP: Free-circulation cooling by the medium.
AFP(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 particles.
Dry installation is possible without cooling system, for intermittentuse only and subject to strict limitations.
Bearings
The stainless steel motor shaft is supported in lubricated-for-life ball bearings.
Shaft sealing
Between the motor and hydraulic section is by means of a high quality, silicon carbide, double mechanical seal. 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 shock.
Discharge
DN 80, 100, 150 and 200 DIN 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.
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 (not in oil chamber on Ex version).
Hydraulics
AFP 0831-0835, 1031-1035, 1533: vortex, open, recessed, four-vane impeller.
AFP 0841-0844, 1041-1049, 1541, 1543 & 2045: Contrablock, open single-vane impeller.
AFP 1546 & 2046: Contrablock, open double-vane impeller.
Motor
Three-phase, 400 V, 50 Hz, squirrel-cage motor as 2-pole (2900 r/min), 4-pole (1450) and 6-pole (980). Protection type IP 68, with stator insulation Class F (155 °C) for standard AFP or Class H (180 °C) for AFP(K) version. Direct starting up to 3 kW; from 4 kW star-delta or direct starting is possible. Motors with other operating voltages and frequencies are also available.
Features
- High-efficiency hydraulic design using Contrablock or vortex impellers.
- Available as standard AFP or higher specification AFP(K).
- AFP(K) has class H insulation and double mechanical seals as standard, with options of seal cartridge and closed loop cooling system.
- Available as explosion-proof.
- Designed for fixed or transportable installation.
- For lifting, AFP has cast eyelet, AFP(K) has stainless steel lifting hoop.
