General Description
QW series submersible sewage pumps consist of submersible motor and pump, separated by oil chamber and mechanical seal. The products are compact with variety of protections to ensure for pump safe and reliable operating.
Design Features
> Submersible Motor: Insulation Class F, Protection class: IP68.
> Motor Protections:
For the motor power range among 3 - 7.5KW, there's a detection electrode for power leakage in the motor casing, the detection electrode is connected to the pump control panel. When leakage, the panel will show the alarm signal to ensure the protection of the pump.
For above 11KW, there is a leakage detection sensor in the motor casing, and a leakage probe leakage electrode in the terminal, also the stator (winding) is mated with motor overload protection device.
> Excellent Performance: Impeller with single or double blockage-free and circum volution-proof passage, enable solids with diameter below 100mm passing freely.
> Easy to install: Fix automatic coupling installation or removable installation.
> Convenient to control: Full automatic control, protections and signals giving out. Easy to achieve ventral monitoring and control.
> Huge investment saving: By using this system, saving construction cost up to 40 - 60%, operation and management cost 30 -40%.
> Pump flange standard: ISO7005, ASME B16.5.
> Bearings: Deep-groove ball bearings, lubricated by grease.
> Shaft seal: Mechanical seal.
Operation Conditions
Fluid: pumping waste, sewage and mud with solids & long fiber.
> Working Temperature Range: -10ºC to 60ºC.
> Operating pressure:
Disc. Size ≤ DN80, PN0.6 MPa - Hydrostatic test pressure = PN1.0 MPa
Disc. Size ≥ DN100, PN1.0 MPa - Hydrostatic test pressure = PN1.6 MPa
> Medium PH value: 5 to 9
> Medium specific gravity (S.G.): ≤ 1.1
> Content of solid particles in the medium: Volume percentage ≤ 4%
> Flexible fiber length: ≤ 50~ 400mm (Different types of pumps have different values )
> Submersible depth: ≤ 8m
> The lowest water level:
When motor power < 15kW, half of the submersible motor can be out of the water.
When ≥ 15kW, totally can be out of the water.
> Motor cooling:
For power < 15kW, using external cooling liquid.
For power ≥ 15kW, using internal self-circulation cooling.
> Starting type: Direct on-line start or controlled silicon soft start, less than 15 times per hour.
> Prohibit un-loaded long time running and reversal running.
Specifications
> Pump Disc. Size: DN50 to DN600 mm
> Capacity Q: 5 to 3750 m3/h
> Head H: 7 to 52 m
> Liquid temperature: -10ºC to +60ºC
> Speed: 50Hz or 60Hz, Variable frequency operation / VFD
> Motor power: 0.75 kW to 250 kW
> Wide hydraulic coverage
The Direction of Rotation
The rotation of the pump rotor is clockwise looking from the motor to the pump.
