Centrifugal Pump Types

Centrifugal pumps use an impeller(s) to add energy to a liquid.  These pumps operate on the dynamic principal of accelerating the liquid (increasing its kinetic energy) and then converting the velocity energy to pressure (potential energy). Liquid enters the inlet port of the pump and is directed to the center of the impeller. The amount of liquid a centrifugal pump moves depends on pump differential pressure. As the pressure increases, the flow rate decreases. A centrifugal pumps performance is shown on a head-capacity curve. Also included on a typical pump performance curve are its efficiency, brake horsepower, and its required net positive suction head.

Features: 

  • Centrifugal pumps are ideal for moving low viscosity liquids in low head, low to high volume applications. Higher heads are possible by using multi-stage versions.
  • Pulsating free flows.
  • Most energy efficient pump for moving large volumes of liquid.
  • Very simple design and compact footprint.
  • Low maintenance, very few moving parts.
  • Has the ability to operate over a wide range of flows.
  • Operates best near the center of the curve (BEP).
