High Pressure Pumps

What is a high pressure pump?

If you have a liquid that you need to pressurize to a high pressure, there are countless options available. Most categories of pumps — including positive displacement pumps, rotary pumps and reciprocating pumps, and centrifugal pumps — contain both low-pressure and high-pressure types. But in general, pumps that best harness the laws of physics are best equipped to generate high levels of pressure. It’s also important for a high pressure pump to have very low clearance between their moving parts and the walls of the pumping chamber.

The amount of pressure generated by a pump depends on three main factors:

  1. the amount of external power applied to the pump
  2. the mechanism used to drive the pump
  3. how well the pump is sealed.

Most reciprocating pumps, for example, harness the power of suction to draw liquid into a chamber before forcing it out in a different direction. The pressure with which the liquid is forced out depends upon the amount of power applied to the piston, diaphragm, or plunger that contracts the pumping chamber.

Other examples include centrifugal pumps, which use the law of centrifugal motion; velocity pumps, which harness the first law of thermodynamics; and booster pumps, which use electricity to boost the liquid's pressure.

Other related Pump Types include: pressure pumps, piston pumps, diaphragm pumps, plunger pumps.
