Positive displacement pumps
A positive displacement pump or volumetric pump is used for transfer of fluids. This pump operates on the basis of increasing and then decreasing the size of the pump chamber by the movement or rotation of one or more pump elements, such as lobes, spindles, gears, rotary pistons or eccentric rotors. This causes a constant volume of fluid to be drawn in and then discharged. We supply Danfoss, Pratissoli, Hawk, VDEG high-pressure sets, Jabsco and Flojet.
