Submersible Sewage Pump

ASW series submersible sewage pump is absorbed in the QW on the basis of similar products at home and abroad advanced technology and features, using the most excellent hydraulic model, special structures and materials, combined with sewage effluent characteristics and the actual needs of the most developed at home and abroad advanced, most feature-complete "third generation" of new sewage pump, its efficiency and performance are superior to similar products at home and abroad.
The pump has a high efficiency energy-saving, non-blocking, anti-winding, long life and other
notable features can be installed with an automatic coupling device. And a common type, auto-mixing type, auto-shredding type, auto-mixing chopped-and anti-flushing-type five kinds of models.
According to market needs, the pump is divided into common type (excluding the ultra-mild leakage protection device) and full insurance-type two kinds. Full insurance-type submersible sewage pump must an pump supporting the use of dedicated control cabinet to achieve the perfect results.

Submersible sewage pump features:

1 Widely Used: suitable for conveying liquid with solid particles of gravel, cinders, tailings,slurry etc. It’s mainly used in river/mining dredging,
2 High Efficiency: pumps are not limited by suction, and thus have high efficiency in slag suction, and clear silt more thoroughly.
3 Powerful Impellers: In addition to the main pump impeller, agitation impeller is equipped at the bottom to help break and mix the sludge.
4 Long Wear Life: The pump is constructed with abrasion resistant materials - chromium alloy.

Submersible sewage pump Structure Material:

Imported SKF or NSK bearing, which, with a reasonable configuration, can oxtend the duration of the pump.
The built-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.
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.
With the optimized design, the impeller will 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 prevent its against contacting with the medium to protect is from corrosion.
