ASW series submersible dredging pumps

ASW series submersible dredging pumps adopts closed-flow channel type impeller, impeller determines the shape and structure, it is suitable for pumping with long-fiber material and large solid particles of the medium.The ASW series submersible dredger pumps mainly used for the dredger. It is easy to use and maintain. You could put the pump to the water directly and much cheaper than gravel pumps or slurry pumps.The ASW pump have advantagesof hi-efficiency, circumvolution proof, lockage free, auto-coupling, hi-reliability and auto-control etc.

ASW series submersible dredging 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.

ASW series submersible dredging pumps is high efficiency, energy saving, non-blocking, anti-winding, long life and other notable features can be installed with automatic coupling device. And a common type, auto-mixing type, auto-shredding type, auto-mixing chopped and anti-flushing type five kinds of models.

Imported SKF of NTN bearing, which, with a reasonable configuration, can oxtend the duration of the pump.
The built in cooling system can make 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 motor from the pump circulation to the cooling barrel and to the pump casing and, when external cooling is required, the cooling sleeve may be separated from the pump casing and individually connected to the cooling system.
Of F class insulation, max. working temperatures 155 C, and of a protective grade IP68 with the effective seal.
Mechanical seal:
Use high quality mechanical seal, two ways of the seal are in series with each other and individually work to separate the motor from the pump seal to provide the motor with a dual protection. 
Oil chamber:
Oil can lubricate and cool the mechanical seal and realize the attached function of safety by preventing liquid from penetrating into the motor. 
With the optimized design, the impeller wil not be blocked up when to transport liquid with its optimum flow and rate and the maximum efficiency. There are suitable impellers at choice for every point of working condition. 
Pump casing:
Use the know-how of CAD/CAM to make it of max. efficiency and min wearability
The pump is coaxial with the motor and the sealing device on the end of the shaft prevents against contacting with the medium to protect is from corrosion.
