D20S Range

Product ID: DT005

The D20S is one of the models of the Dosatron water-powered dosing pump. It operates on a volumetric dosing principal, meaning that any changes in water pressure or flow do not affect the accuracy of the injection of concentrate.

The injection rate is externally adjustable by simply turning the doser of the pump to the desired rate. The D20S is equipped with a security valve which will open and let the water flow through in case of inopportune stop of the motor. It also contains a built-in bypass, air bleeder and anti-siphon device.

Also included with the pump are: support legs, mounting bracket, suction hose, weighted strainer, vacuum breaker device + connection and quick start guide.
