Features & Cautions

  • 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)
  • The viscosity of pumping liquid.
    – Model DWS & DWM : Below 50cp – Model DWA & DWB & DWC : Below 1000cp
  • The capacity increases the twice or three times or even more depends on head number.
  • Above specifications are that should be changeable due to improvement etc without any notice.

The motor is 3 phase, 220/380v. The type is diaphragm metering pump.
According to fluid type, material of headcan be changed such as PVC, SUS304, 316, TEFLON, PVDF.
The range of capacity is from 25cc/min to 35000cc/min, but attach the head one more in parallel, capacity might be double.
