Variable ratio typeTWINFLOW VR-50/100

Variable ratio type TWINFLOW VR-50/100

A high-precision volumetric metering system that dispenses fixed volumes free from the effects of changes in liquid viscosity.

  • This volumetric metering type posi-load pump contributes to high-precision metering and dispensing since it is not affected by changes in material viscosity.
  • As a variable-ratio dispenser, it provides a wide range of mixing ratios.
  • All necessary switches used during operation are mounted on the control panel, allowing the operator to perform proper tasks without difficulty.
