Submersible Sewage Pump

Description

ASW 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

ASW pump 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.

Structure

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 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.

Motor

Of F class insulation, max. working temperatures 155 C, and of a protective grade IPX8 with the effective seal.

Mechanical seal

Use high quality mechanic 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.

Impeller

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

Shaft

The pump is coaxial with the motor and the sealing device on the end of the shaft preven ts against contacting with the medium to protect is from corrosion.
