Category: Centrifugal Pumps

An end suction centrifugal pump is one of the most widely used pieces of equipment for transferring fluids from one location to another.

How does a Centrifugal Pump work?

A centrifugal pump works on the basis of adding energy to the liquid being pumped by a rotating impeller increasing the pressure and flowrate as it rotates. Basic principle says that the faster you rotate the impeller the more flow and pressure will be generated. If you double the rotational speed you will double the flowrate whilst increasing the pressure by the power of 4 and the absorbed power x the power of 8.

ESI supply a wide range of industrial / heavy duty process centrifugal pumps, ranging from ANSI, ISO, long coupled, close coupled and discpac technology. Our product specialists can identify which centrifugal pump will best suit your process/application.

Types of Centrifugal Pumps

  • Overhung Impeller
  • Between Bearings or Turbine Type

They can have various impeller designs such as open, semi open, closed impellers or double suction depending on the type of application required.

Categories of Centrifugal Pump Designs

  • ANSI
  • DIN
  • ISO

Centrifugal Pump designs can be customised depending on the clients’ site standards or preference.

Applications of Centrifugal Pumps

  • Waste water treatment applications
  • Circulating of heat transfer fluids through heating and cooling systems for industrial markets
  • Mixing and transferring of liquids within industrial, chemical, pharmaceutical and petrochemical industries where heavy duty process pumps would be required.
  • Any process where liquid must be moved from one location to another.
