Centrifugal Pump

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. In the typical case, the fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits. 

 

Positive Displacement Pump

These pumps move fluid using a rotating mechanism that creates a vacuum that captures and draws in the liquid. Rotary pumps are very efficient because they naturally remove air from the lines, eliminating the need to bleed the air from the lines manually.

Rotary positive displacement pumps fall into three main types:

  • Gear pumps - a simple type of rotary pump where the liquid is pushed between two gears
  • Screw pumps - the shape of the internals of this pump is usually two screws turning against each other to pump the liquid
  • Rotary vane pumps - similar to scroll compressors, these have a cylindrical rotor encased in a similarly shaped housing. As the rotor orbits, the vanes trap fluid between the rotor and the casing, drawing the fluid through the pump.

 

Diaphragm Pumps

A diaphragm pump (also known as a Membrane pump, Air Operated Double Diaphragm Pump (AODD) or Pneumatic Diaphragm Pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.

 

 

All of our pumps are carefully selected to provide the correct flow rate and pressure at the final discharge point.
