FEDOS E 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.
Classic piston dosing pump
The FEDOS E combines the properties of the FEDOS series working reliably for many years with the latest requirements in dosing technology. Advantages of piston dosing pumps: little dependency on back pressure and linear flow variation as a function of stroke length. Due to an improved flexibility and the further development of individual components, the pumps can be integrated even more efficiently in dosing processes. Heads and pistons are the same as for the previous pumps so that the continuity of spare parts keeping and service is ensured.
