Pump Features:  

1.Type WN gravel pump is of horizontal cantilevered single-casing centrifugal pump. 
2. Construction of this pump is It can be equipped with diesel engines or be equipped with motor

driven directly. It has the advantages of working stability, little vibration, low noise and low hydraulic

loss, high efficiency, low fuel consumption and small size, light weight, simple structure,easy mainte-

nanceof single casing connected by means of clamp bands and the discharge directionof pump can

be oriented in any direction of 360. the type of pump possesses the advantages of easy installation.

3. The cylinder –type bearing assembly with oil lubrication is adopted by the pump. It is suit for adjusting

the distance between impeller and pump. The bearing assembly uses oil lubrication.

4. Three kinds of shaft seal---mechanical seal, expeller seal and packing seal 
5. Wide passage , good performance of NPSH, anti-wearing and anti-corrosion, and high efficiency,

6. The type of driver just have v belt driver, gearbox driver, elastic coupling driver, fluid couplings driver,

frequency conversion driver, silicon controlled rectifier speed regulation etc.
