Hydraulic diaphragm

JMZ series

Hydraulic diaphragm metering pump, up to 3,700 L/h at up to 340 bar

JMZ series: hydraulic diaphragm metering pumps for accurate, repeatable dosing of chemicals and additives. 84 models from 43 to 3700 L/h, with pressure up to 340 bar. Pump-head and diaphragm materials are chosen for your liquid; send us the chemical, concentration and temperature and we will confirm the right head.

  • Hard, compact design with better sealing than plunger-type pumps
  • Variable eccentric adjustment for smooth flow pulsation
  • Refill valve for balanced hydraulic oil replenishment; adjustable safety valve
  • Double diaphragm with rupture alarm recommended for corrosive, flammable or explosive media
  • Power 380 V three-phase, 220 V single-phase or three-phase, 50/60 Hz; variable-frequency control (4–20 mA) or on/off motor control

PartWhat it does
DiaphragmThe flexing membrane that moves the liquid; replaced at the service interval
Check valves (suction and discharge)Valve balls, seats and springs that give one-way flow
Pump headLiquid end in the material suited to the chemical
Gaskets and O-ringsSeal the head, valves and connections
Hydraulic oil and relief / bleed valveHydraulic diaphragm types only: transmits the stroke and protects against over-pressure
Stroke adjuster and motorSets the flow rate and drives the pump
