Select-380 Doser

  • The high pressure Select Doser for water treatment.

    This versatile doser can be used as a proportional doser taking a pulse from a standard water meter, or pulses from standard Dosing Solutions flow sensors. Dosing into line pressures of up to 5 bar (70 psi), it is the ideal doser for water treatment.

    This is the ideal doser to use for water treatment when water line pressures are relatively high, and the dosed product requirement is low.

The Select 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-380 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.
