Rotary pumps are compact, high-pressure systems that provide continuous flow of liquid in a variety of applications across many industries. Rotary gear pumps transfer nonabrasive or nonparticulate viscous liquids with a continuous, near-pulseless flow. Rotary vane pumps are high-pressure pumps that transfer diesel fuels and light oils. Roller pumps filter and transfer cooking oil in food service applications such as commercial fat fryers. Beverage pumps are vane pumps that dispense drinks from soda fountains or pull shots from espresso machines.
