Showing how it works. The unique design of the DIY-Dredge allows you to hover the pump over the bottom which makes it very efficient. The centrifugal pump is equipped with a mill that effectively grinds down the roots of reeds and other seaweeds. The silt mixture of mud and weed is excellent for the garden etc. See a customer dredging sand here.

Self-priming pump | KSB

Centrifugal pumps which are not designed with an internal or external self-priming stage can only start to pump the fluid after the pump has initially been primed with the fluid. In addition, a suction-side swing check valve or a vent valve must be fitted to prevent any siphon action and ensure that the fluid remains in the casing when the pump has been stopped.

Two Important Points about the Pump Inlet and Outlet

2017/1/3· Usually the suction pipe diameter of the pump is generally larger than the outlet diameter, according to the pipe diameter of different suction flow rate is also different. When the diameter is less than 250mm, it is 1~1.2m/s, when the diameter is 250~1000mm, 1.2~1.6m/s, technically, the maximum speed of water should not exceed 2.5~3.0m/s, the minimum speed should not be less than …

Cavitation - Wikipedia

Discharge cavitation occurs when the pump discharge pressure is extremely high, normally occurring in a pump that is running at less than 10% of its best efficiency point. The high discharge pressure causes the majority of the fluid to circulate inside the pump instead of being allowed to flow out the discharge.
