Hydraulic diaphragm

JMX series

Hydraulic diaphragm metering pump, up to 1,600 L/h at up to 282 bar

JMX series: hydraulic diaphragm metering pumps for accurate, repeatable dosing of chemicals and additives. 74 models from 28 to 1600 L/h, with pressure up to 282 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 protects hydraulic parts from damage
  • 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

Spare parts for JMX series

Typical wear and service parts for this type of pump. The exact part, material and part number depend on the model, so send us the model code (or a nameplate photo) and we confirm and quote the right one.

Request spare parts quote
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
