Chemical-resistant proportioner has a built-in check valve to prevent back filling into the concentrate tank.

Prevent back filling into the concentrate tank with this 3/4", self-cleaning polypropylene Dosatron® Proportioner. It is chemical-resistant and includes a built-in check valve. This 2 GPM proportioner operates from 7 PSI to 58 PSI and handles hot water up to 160° F.

Features/Specifications:

  • Flow rates up to 2 GPM at 58 PSI in the ON mode
  • Flow rates up to 13 GPM at 58 PSI in RINSE mode
  • Injection rate - 1:100 (1%) to 1:2.3 (43.6%)
  • Maximum temperature 160° F
  • Built-in check valve
  • Suction valve and strainer
  • Maximum vertical height from concentrate tank: 6'

A simple quarter turn of the handle changes the function from dosing (ON) to rinsing and a system of 12 color-coded tips are provided for various injection rates. Back flush mode allows for easy cleaning.

These results were obtained injecting water. Product viscosity will change these rates.

  • The higher the viscosity, the lower the injection rate
  • The higher the pressure, the lower the injection rate
  • Constant pressure and flow conditions are required to obtain repeatability (constant injection results over time)
