MPE(S)Series submersible cutting pump and cutter pump

The purpose of MPE (S) series submersible cutting pump and cutter pump

Community, municipal pipeline networkcomprehensiveSuitable for wastewater containing long fibers in the medium, including sewage treatment plants, underground water treatment equipment in buildings, and subway engineering. Wastewater discharge from food, leather, pulp, printing and dyeing, steel and other products.

Discharge of sewage from slaughterhouses and rural biogas digesters.

Industrial drainage, other water use, and drainage for other purposes.

For sewage removal from living unit and house in scattered settle ment where the laying of a conventional sewer would be too expensive,or where large ground undulation are present, or where it is only possible to lay pipe lines of small diameter.

For sewage removal from motorway resting sites, communal buildings and for renovation of buildings or parts of a city.

For use in slaughter houses,food processing plant, paper factories, agriculture and similar areas.

Pump operating medium/Medium Pumped

Faecal matter and heavily polluted sewage, max. medium temperature： continuous operation =40*C, if unit submerged, shortterm to 60tJ

Continuous long-term operating temperatureless than40°CImmersion of the entire machine, short-term operating temperatureless than60°C.

designDesign

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

Motor： Three-phase 380-415V or single-phase 220-240V 50Hzor 60Hz, Insulationclass F. protection type IP68,cooled by amply dimensioned cooling areas.

Motor: Three phase squirrel cage motor380-415V, Or single-phase 220-240V, frequency of 50 or 60Hz. Insulation level F, protection, etc. lP68

Bearing： The motor shaft is supported in lubricated-for-life maintenance -free ball bearings.

Bearing: ImportedNSK bearings.

Shaft Sealing between motor and hydraulic section and motor side by means of high quality sealing units using two silicon carbide mechanical seals, independent of direction of rotation and resistant to temperature shock.

Mechanical seal: Adopting a dual channel series mechanical seal.

Discharge/Outlet diameter:MP75-4OO=DN5O with ISO-flange

MP550-750=DN80 with ISO-flangea

Shredding Systemconsisting of spiral bottom plate with stationary cutter ring with cutting edges and a shredding rotor located before the impeller for optimum blockage-free running.

The design of the water pump components is advanced and reasonable. A cutting rotating blade is installed in front of the water pump impeller, and a fixed blade is installed at the inlet to thoroughly crush impurities in the suction medium before entering the impeller flow channel, without any blockage.

TCS— Thermo— Control— Systemby means of thermal sensor in the stator to give a warning and switch off the motor in the event of excessive temperature occurring.

Temperature overheat protection: The motor is equipped with a pre-set thermal switch, which can prevent overheating when the temperature exceedsAt 135 ° C, it automatically disconnects to protect the motor.

DI—System for Seal Monitoringconsisting of an electrode in the oil chamber and optical and/or acoustic inspection indication should leakage at the shaft sealing occur.

Leakage monitoring: Install leakage monitoring probes in the oil chamber.
