Water trash pumps are the work horses assigned to cleaning up after building work, floods and other natural disasters. They are designed to handle the maximum possible load by providing large inlets and handling solids as well as water.
How do They Work?
Rather than working on the liquid and trash mixture directly, the trash pump uses a pump mechanism to create a very low pressure area above the level of the fluid. Fluids always follow the line of least resistance and are drawn to fill low pressure areas. The fluid that has entered the low pressure area of the trash pump will cover an impeller within the trash pump.
As the impeller spins it creates a centrifugal force that acts on the fluid and forces it into the pump outlet. As the fluid is ejected and the pump mechanism continues to create a low pressure area, a siphon effect is created. The amount of solid matter that a sump pump can move effectively is affected by the design of the impeller and the number of blades.
Sump pumps can be powered in many different ways including AC/DC electricity and gas or diesel engine and are suitable for cleaning up in any situation.
