Ultimate metering accuracy

Wanner_Internationa_hyda_cell_l.jpgHYDRA-CELL Metering pumps are said to enable users to meet or exceed API 675 performance standards with virtually pulse-less, linear flow. The company says these pumps achieve superior levels of accuracy, repeatability and linearity, while delivering precise, constant flow by employing unique hydraulic oil management systems.To maintain accuracy in a hydraulically-actuated metering pump, the volume of oil on the non-process side of the diaphragm must remain constant.

Conventional metering pumps rely on vacuum sensing or mechanical activation to compensate for leakage past the plunger and may not compensate on every pump stroke.Hydra-Cell pumps incorporate a replenishment valve in every piston assembly which operates on the suction stroke, thus ensuring optimum actuating oil volume on every diaphragm pressure stroke to provide superior accuracy.
