Big piston dosing pump

Rekos pumps can be supplied as simplex piston dosing pumps type KR and duplex piston dosing pumps type ZKR.
Advantages of piston dosing pumps are: minor dependency on back pressure and linear flow variation as a function of the stroke length. The dosing pumps are therefore very suitable for proportional dosing where the stroke length is adjusted by means of a remote control signal.
