Nexus' Vertical Multistage Pumps & Booster Set

Nexus Pumps logo
Nexus vertical multi-stage booster pump systems are designed for high pressure and/or high flow applications. They are particularly effective in delivering pressurized water to high-rise buildings, manufacturing complexes and other large facilities. Industrial and municipal plants benefit from booster pump sets for efficient delivery of fresh water and removal and treatment of wastewater. These vertical booster pumpsets can be regulated by a variable frequency drive that controls the pump operation to maintain constant pressure regardless of varying demand and fluctuation in incoming pressure. Pumps in the set operate in a synchronized manner to supply the specified flow and pressures.

Multistage pumps are centrifugal pumps with two or more stages. Each stage contains one impeller and a diffuser. The impellers, though, are connected by a single shaft only. As the fluid enters the first impeller, it gains higher velocity and is deflected to the diffuser of the next stage. Here, the fluid gains pressure. The fluid is then rotated by the next impeller at the next stage causing it to rise to the tips of the impeller and fall to the next stage where it gains additional pressure. The process goes on until the fluid reaches the last stage. The fluid then exits the pump through the discharge port with the highest pressure the pump can possibly generate. That said, multi-stage pumps are ideal for pressure boosting and in applications with high head requirements.
