Structure type

The flow parts are all metal

Coated lining or rubber lining

The pump is horizontal, single stage, single suction, cantilever type centrifugal slurry pump; This type of pump uses high speed operation, and adopts a centrifugal impeller with wide flow channel, and the back of the impeller is cast with auxiliary blade structure; Pump cover adopts back pull out structure. The pump body has a replaceable wear-resistant metal lining or rubber lining, and the impeller is made of wear-resistant metal. The pump body can take different exit Angle directions according to user requirements.

Pull-out structure

The pump is connected to the motor or speed regulating mechanism by lengthening the diaphragm flexible coupling, and the rotor parts can be withdrawn for maintenance without disassembling the inlet and outlet pipes.

Bearing body parts adopt bracket structure, pump end adopts imported double row tapered roller bearings, drive end adopts two disc cylindrical roller bearings. Thin oil lubrication.

The shaft seal is packaged mechanical seal.

Rotation direction

From the driving end, the pump rotates clockwise. The rotation direction of the pump can also be changed according to the needs of the user's on-site pipeline installation.

Technical characteristics

▶ Using foreign excellent water conservancy model, and using advanced computer simulation analysis technology (Solidworks, ANSY, Flowworks and other software platforms), the pump has reliable performance and high efficiency.

▶ The material selection of pump flow parts is reasonable, advanced, long service life, sprayed with KD.L-201 abrasion resistance lining coating, to meet the wear resistance and corrosion resistance requirements of conveying different media mining slurry.

▶ Absorb the structural advantages of domestic and foreign large slurry pumps and mud boat pumps, advanced structure, simple, easy maintenance, reliable operation.

▶ The bearing body adopts a simple structure, and changes the position of the impeller in the pump chamber by adjusting the bearing components, so that the pump group is always in an efficient operation state.

▶ The shaft seal is packaged mechanical seal, easy to install and maintain, and does not require external cleaning industrial flushing water.

Material of main parts

Note: KD.L-201 is a new type of anti-corrosion and wear-resistant spray material developed by the Key Laboratory of CFC, College of Aerospace and Materials Engineering, National University of Defense Technology.

Complete range

Complete supply pump, motor, governor mechanism, coupling, common (or pump itself) base plate.

Pump Water performance table

Note: 1, the above motors are calculated and selected according to the slurry specific gravity 1.15, the user chooses the motor, should be calculated according to the specific medium specific gravity of the motor supporting power;

2, can also be equipped with high-speed motor + speed regulating mechanism or impeller diameter small range change to meet the user's different parameter requirements.
