Radial vane pumps

This type of pump works based on a principle that "increased space sucks in liquid, and decreased space pushes out it". Its rotor has a number of vanes arranged radially. The rotor is eccentric to the pump casing, so the volume between two venes is enlarged and reduced cyclically as the rotor turns. This continuous movement causes the liquid (fluid) to be sucked in and discharged, so the pump can transfer the liquid smoothly even at a low turning speed. It can transfer the liquid regardless its characteristics (e.g. high-viscosity, foam), and it self-feeds. This is the apealing advantage of this type of the pump.

Principle of operation of the vane pumps

Improved durability and wear resistance
High-viscosity liquid, slurries, and foams are all acceptable.
Variable discharging volume
Suited to the liquids for which agitation is prohibited.
