Submersible Sewage Pump Product Description

QW series submersible sewage pump is based on the advanced technology of domestic and foreign similar products. We have many years of experience in design and manufacture. After several rounds of technical innovation,it has become more functionally reliable and sophisticated. Its design has been streamlined with chart playing and it has advantages such as high efficiency.winding protection,no clogging,high reliability, automatic coupling,automatic control and automatic protection. It is versatile and has a large working scope. The pump and the motor are sharing the same shafts to form a compact structure. So it is easy to maintain. Upon customer's request,various submersible sewage pumps are available to meet voltage requirements. This pump has a outlet diameter 50- 600mm,a flow rate 7- 6000 m3 /h, a head 5 ~ 60m,a power 0.75-450kW and a voltage 380V(660V,3kV,6kV and 10kV are also available upon customers' demand).We could also offer hyperthernal, vearable, explosion proof submersible sewage pump of special design upon customer's demand.

Applications and operating conditions

QW series submersible sewage pump is mainly used in municipal engineering ,industry & agriculture, hospitals, buildings,hotels
and restaurant to transport waste water,urban sewage and rainwater,which contains solid particles and filaments,as well as in
raw water supply,aquiculture and irrigation(with special material,it can be used with a corrosive medium).lt is fitted with selfprotected devices and control cabinet and can control the water level according to customers' requirements.

Features:

The impeller adopts particular larg channel structure, so the drain capacity has been improved greatly. It can effectively pass the solid grain whose diameter is about 50% of the pump caliber
To improve the application safety , the pump can be fixed with various protective devices according to the sonsumer’s requirements,including stator winding temperature-rise protection, bearing temperature-rise protection, oil chamber water leakage protection etc devices.
It adopts inner self flow circulation system. The motor is cooled by liquid, so it is safer to use. At the same time, the electric pump can be installed in dry and fixed form by this structure.
Mechanical seal adopts the latest material and is made with extra care, so its life is over 8000 hours
It can adopt double-way and automatic coupling installation device which makes the installation,maintenance of the unit convenient and quick.
To realize automation management we will equip various forms sewage special control cabinet according to the consumer’s requirements.
