Nexus' Trash Pumps

The Nexus semi-trash pumps are close-coupled, self-priming centrifugal types that are electric motor-driven. They are engineered to handle large amounts of water that contains hard and soft solids such as mud, leaves, twigs, sand, and sludge. These pumps are also capable of processing materials with suspended particulates that would clog standard centrifugal pumps.

Although they can allow the passage of solids with sizes up to 24 mm only, they do not clog and finish the job in a minimum amount of time.

Nexus self-priming trash pump with heavy-duty blue cast iron casing and electric motor mounted on a steel base. Designed for handling solids-laden fluids in construction, wastewater, and dewatering applications requiring reliable, high-flow performance.

PRINCIPLE OF OPERATION

Trash pumps use centrifugal force to move a fluid. In this case, a Nexus trash pump is also self-priming. In the priming stage of the self-priming principle, the impeller rotates to generate vacuum at the center. This draws air into the pump from the suction. Simultaneously, the pump creates a cylindrical ring of fluid on the inside of the casing. This causes a gas-tight seal to form. Meanwhile, air bubbles are trapped in the fluid inside the pump and are forced out through the discharge port. As soon as air is expelled, the liquid returns to the pump. As the fluid gradually rises and all the air is discharged, the normal fluid pumping using centrifugal working principle commences.
