WQ SRIESE SUBMERSIBLE SEWAGE PUMP

 

PURPOSE

WQ series submersible sewage pump is mainly used for municipal works, industrial buildings, hotels, hospitals, civil air defence, mines etc. Trades to drain off the sewage, waste water, rainwater and living water in cities containing solid grains and various long fabrics.

MODEL MEANING

50WQ 15-8-0.75

50: Drain aperture

WQ: Submersible sewage pump

15: Capacity(m³/h)

8: Head (m)

0.75: Power of fitted motor (kw)

CONDITIONS USE

The medium temperature should not be over 60°C,the density 1200kg/m³, and the PH value within 5-9.During running, the pump must not be lower than the lowest liquid level ,see “ lowest liquid level” in the drawing of installation dimensions(covering the automatic cooling system), means lowest liquid level without no automatic cooling system.Rated voltage 380V, rated frequency 50HZ. The motor can rub successfully only under the condition the deviations of both rated voltage and frequency are not over ±5%.The maximum diameter of the solid grain going through the pump has not to be larger than 50% of outlet.

ROTATING DIRECTION

The impeller rotates CCW as viewed from the suction.

STRUCTURES DESCRIPTION

Bearing: Imported SKF of NTN bearing, which, with a reasonable configuration. Can oxtend the duration of the pump.

Cooling: The buit-in cooling system can have the pump normally work whether the motor is on or under the liquid surface. A part of the liquid is extracted to bring out the beat produced by the pump casing and, when extermal cooling is required, the cooling sleeve may be separated from the pump casing and in-dividually connected to the cooling system.

Motor: Of F class insulation, max. working temperature 155c, and of a protective grade IPX8 with the effective seal.

Pump casing: Use the know-how of CAD/CAM to make it of max. effi-ciency and min wearability.
