Features & Benefits

  • Hydraulic actuated diaphragm metering pump design.
  • SS304, SS316 and SS316L liquid-end material, suitable for high pressure chemicals.
  • Pump diaphragm in PTFE multi-layer type, long service time and high accuracy.
  • Oil bath gear lubrication eliminates the maintenance required by auxiliary oil systems.
  • Lockable micrometer stroke, adjustment can be adjusted while pump is running or stopped.
  • Together with the variable speed drive or stroke controller, the automatic operation is achieved.
  • Integral built-in hydraulic relief valve and bleed valve, as protection against overload.
  • Suitable for the corrosive, flammable, explosive and toxic chemicals in high pressure condition.
  • Duplex or triplex heads are available. Multiplex gear box with one motor drive.
  • Double diaphragm with leakage alarm device is available.

Motor Optional

  • Power supply: standard in 3 phase/50Hz/380, 4 poles motor.
  • 60Hz/440V or other voltage motor available.
  • Enclosure of protection, IP55, Insulation, class F, IEC standard.
  • Other motor options: explosion proof motor and variable frequency motor.

Flow Adjustment

By the manual micrometer.
By the variable frequency motor together with the inverter or other variable speed drive.

Double Diaphragm with Leakage Alarm Device

When for the toxic & explosive liquid, double diaphragm with diaphragm rupture detecting system is available.
It can always monitor the leakage; once the diaphragm ruptures, it can alarm in 0.2 to 6 second, and stop the pump immediately.
