china centrifugal dredge pump factory

For certain types of slurry pumping conditions, positive displacement pumps may be a more suitable option than centrifugal pumps.

When pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.

- By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.

Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.

600WN to 1000WN dredge pumps are of double casings, single stage cantilevered centrifugal pumps. These pumps are equipped with frame and lubrication is force thin oil. The design of double casing the pump working till the volute liner almost worn down and guarantee no leakage when volute liner is worn down.
