Motor-driven Piston Dosing Pumps

Piston dosing pumps are particularly precise dosing units, which are not dependent on pressure. Dosing capacity varies proportionally with the stroke length and can be set to the tiniest repeatable quantities. Two-piston and multiple-piston pumps are therefore particularly suitable for delivering precise mixtures, where different media must be mixed at a constant ratio which can be selected as desired. Using externally controlled drive motors, the total quantity can be varied from 5% to 100% at a constant ratio. Heated heads allow the dosing of media that are torpid when cold. A piston flushing skirt is available as an option, to prevent damaging leaks and protect the packing materials and pistons from abrasive chemicals.
