Rotary pumps are used in a wide range of applications -- liquids, slurries, and pastes.   And because rotary pumps displace a known quantity of liquid with each revolution of the pump shaft, they are a popular choice for metering applications.  They can accommodate thin to high viscosity liquids, high vacuums to high pressures, and minute doses to high capacities. 

Rotary pumps are available in a number of different pumping principles, each with its own unique set of advantages and disadvantages.

The following principles comprise the majority, but not all of the rotary pump market.  Please check back as we continue to add principles to the list.
