Motor Driven Diaphragm Metering Pumps

  • Maximum Flow Rate: 200 L/h
  • Maximum Pressure: 15 kg/cm²g
  • Mechanically Actuated Diaphragm

The GMZ Series motor driven diaphragm metering pumps are designed for reliable and accurate dosing in industrial processes requiring higher flow rates and stable mechanical performance.

Equipped with a mechanically actuated PTFE faced Hypalon diaphragm and oil bath lubrication, the GMZ Series ensures smooth operation, reduced wear, and long service life. The slider polar crank mechanism minimizes pulsation while enhancing mechanical stability, making these pumps suitable for continuous-duty applications.

With flow rates up to 200 L/h and pressures up to 15 kg/cm²g, the GMZ Series offers a robust solution for water treatment and industrial chemical dosing applications.

  • Max flow rate: 200 L/h
  • Max pressure: 15 kg/cm²g
  • Mechanically actuated diaphragm
  • Long‑life PTFE‑faced Hypalon diaphragm
  • Simplex pump configuration
  • Stroke adjustment via slider‑polar crank mechanism for reduced pulsation
  • Stroke adjustment while running: 0 to 100%
  • Accuracy: ±2% of rated flow from 10% to 100% stroke
  • Suction lift: Up to 1.5 m water
  • Turndown ratio: 10:1
  • Oil‑bath lubrication for enhanced mechanical durability
  • Handles liquid viscosity up to 100 cPs
  • Maximum pumped liquid temperature: 50°C
  • Stroke adjustment lock for consistent operation

 

* Special materials of construction (PVDF, SS316L, etc.) available on request
