Piston metering pumps

Piston metering 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.

FEDOS E/DX

A classic piston dosing pump: tradition meets innovative technology

The FEDOS E and FEDOS DX combine the properties of the FEDOS series working reliably for many years with the latest requirements in metering technology.

Due to an improved flexibility and the further development of individual components, it can be integrated even more efficiently in metering processes. Heads and pistons are the same as for the previous pumps so that the continuity of spare parts keeping and service is ensured.

REKOS KR


The large piston dosing pump: power meets precision

REKOS pumps are available as Type KR single-piston dosing pumps. The advantages of the piston dosing pump are its low dependence on the back pressure and the linear change in dosing quantity with the stroke length.

These dosing pumps are therefore well-suited to proportional dosing, where the stroke length is changed in dependence on a remote control signal.

KARDOS KN/N


Powerful piston dosing pump

KARDOS stands for a group of precision dosing pumps which have been developed especially for applications with a high demand for accuracy, reliability and flexibility in a wide performance range. The symmetrically designed gearbox allows the arrangement of 4 dosing heads on the same level and the stacking of three heads above one another, thus enabling a maximally 12-head pump. Each dosing head is 100% adjustable independently.
