Motor-driven Piston Dosing Pumps

Piston metering pumps are particularly precise and independent of back pressure. The quantity is adjusted in proportion to the stroke length, their reproducibility allows dosages for extremely small quantities. Pumps with two or more pistons allow exact mixtures or at constant ratio between different fluids to be dosed. Using externally controlled drive motors, the total quantity can be varied from 5% to 100% at a constant ratio.
