Select Doser 648 - Twin Head


  • The Select 648 dosing system has been designed for use in agricultural and other situations where products are required to be dosed into water proportionately to the flow.

    The Select 648 incorporates a powerful motors and gearboxes to give reliable and trouble-free performance.

    Using a peristaltic pump has the advantage that dosed products, regardless of how aggressive they are, only come into contact with the pump tube, not the working parts of the pump. Removing the old tube and fitting the new one effectively cleans and renews the pump.

Proportional Dosing:

The Select-648 is powered from a single power supply or battery, and has a single input from a water flow sensor or water meter.
Each side of the pump (left and right) operates independently. It is therefore possible, for example, to have one side of the pump set to dose at a ratio of 1:10,000 and the other side to dose at 1:25,000.
