1730 Series Hydraulically Actuated Metering Pump

MEMDOS GMRThe 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.

  • A micrometer stroke length adjustment allows effortless capacity control of 0-100%
  • Pre-stressed tubular diaphragm withstands higher vacuum for longer life
  • Max. operating pressure up to 3000 psig
  • Power supply - single phase or 3-phase TE or XP motor
  • Built-in hydraulic pressure relief valves
  • Unique hydraulic vent and refill system
  • Single ball cartridge type check valves
  • Long term reliability and accuracy
  • Tungsten Carbide check valves
