Features & Cautions

  • Without spring to help suction process, the technique which is crank rod mechanism is adopted to this product.
  • The suction and discharge process are very accurate more than the previous model due to crank rod mechanism.
  • The crank rod mechanism guarantee the lager capacity and the higher pressure.
  • Simple, Economic Vertical type Metering pump by reasonable design.
    – Extremely good life by long operation
    – The range of effective adjustment stroke : 20%~100%
    – The temperature of pumping liquid : 0~100℃
    – The viscosity of pumping liquid is Below 1000cp
  • Simple, Economic Vertical type Metering pump by rationalistic design.
  • Extremely good life by long operation.
  • The range of effective adjustment stroke : 15~100%
  • The temperatures of pumping liquid : 0~50℃ (Material : PVC), 0~80℃ (Material : SUS)
  • Above specifications are that should be changeable due to improvement etc without any notice.
