Industrial pumps fall under two main types: positive displacement and dynamic pumps.

When we look at the many types of industrial pumps, we first need to separate them down into classes based on the displacement methods they use and then further into subtypes. 

Positive Displacement Pumps

Positive-displacement pumps operate by trapping a certain amount of fluid and displacing or forcing it into a discharge pipe. Positive-displacement pumps can be further separated into other categories by the mechanism they use to displace the fluid.

  • Rotary-Type Positive Displacement Pumps: Rotary-type positive displacement pumps use a rotor in the mechanism to move the fluid through. They can be further classified into three main types: gear pumps, screw pumps and rotary vane pumps.
  • Gear PumpsGear pumps are a simple type of pump where the liquid is pumped between at least two gears that create a vacuum forcing the liquid through.
  • Screw PumpsScrew Pumps use one or more screws to move liquids along the screws axis. For example, with three spindle screw pumps, the screws rotate in the opposite direction from each other, and the liquid being pumped moves along the screw spindles.
  • Rotary Vane Pumps: A rotary vane pump is made up of vanes mounted to a rotor that rotates inside a cavity. They are great at enduring short periods of dry operation, and so they are considered good for jobs involving low-viscosity fluids.
  • Reciprocating Positive Displacement Pumps: Reciprocating positive displacement pumps work by using one or more oscillating piston, plunger or diaphragm to move the liquid or gas. Reciprocating-type pumps include piston pumps, plunger pumps or diaphragm pumps.
  • Linear Positive Displacement Pumps: Linear-type positive displacement pumps such as rope pumps and chain pumps are similar to reciprocating pumps but the displacement takes place linearly.


Dynamic Pumps

Dynamic pumps are available in different types but most commonly they include centrifugal pumps and self-priming pumps.

  • Centrifugal PumpsThese types of pumps are one of the most popular and commonly used pump for moving and transferring liquids. It uses a rotating impeller to move fluids by using centrifugal force. These are the undisputed pump choice especially for delivering liquid from one location to another in numerous industries. 
  • Drum And Barrel PumpsMagnetically coupled pumps and drum and barrel pumps are also types of centrifugal pump. Drum and barrel pumps are designed to provide a safe and simple way to transfer almost any chemical from containers like barrels or drums, hence their name.
  • Self Priming PumpsA self priming pump is a type of centrifugal pump which uses an air and water mixture to make a completely primed pumping state. This type of pump can be used in various applications, which include dirty water and chemical uses.
