Select 640 Pump


Dosing system designed for use in agricultural and other situations where products are required to be dosed into water proportionately to the flow.

The SELECT-640 doser is British made and incorporates a powerful motor and gearbox 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.
A series of simple on-screen menu commands allow the operator to choose between a number of pre-set allowable dosing ratios. 
Accuracy is achieved with a unique system of continuous monitoring and adjustment of the pump rotor performance and by a new and unique system of Accumulated Flow Data.
