The Model 1730 metering pump is a hydraulically actuated tubular diaphragm design, utilizing a pre-stressed diaphragm and vertical plunger configuration. The memory of the pre-stressed diaphragm returns to its exact reference position on every suction stroke giving the pump exceptional accuracy, outstanding lift capabilities and minimal NPSH requirements. The ability of the diaphragm to withstand higher vacuum prevents premature diaphragm failure. The unique hydraulic system provides the industry with the simplest and most reliable actuated design for metering pumps.
