What is the "solenoid drive system?"
Magnetic force is generated on the solenoid coil by the power circuit built into the electronic circuitry to push out the diaphragm. As each single shaft advance and retraction operation can be controlled, this means that the flow rate can be controlled to higher precision.

Demonstrating thorough rigidity, high precision, and reliability, this series of large-capacity metering pumps can be put to effective use in an extensive range of fields including the chemical and food industries, and water treatment.

The major feature of the R series metering pumps is its stable discharge precision. This has been effectively utilized in maintaining high reliability during extended continuous operation. This is a vital condition for large-capacity metering pumps put to use in large-scale processes in the chemical and food industries, and water treatment.
Another great feature of the R series is that you can select from a highly functional and safe applied product group as if you are ordering a custom-made product.
The R series provides you with a lineup of models that fully answers today's large-capacity metering pump needs.

  • Do not use outside the temperature range below as this may result in failure:
    Ambient temperature: 0 to 40 ºC
    Requirement for liquid being handled:
      Liquid temperature: PVC type: 0 to 40ºC
    SUS type: 0 to 80ºC
    (no freezing allowed)
      Viscosity: 50 MPa•s or less
    Max. discharge pressure:
      See Performance Specifications.
      Max. discharge pressure becomes 1.0 MPa when the pump head is made of PVC (VEC, VES, VTC models).
  • Hydraulic diaphragm type is not intended for pumping slurry. Use a hydraulic double-diaphragm type if the liquid to be pumped contains slurry.
