with rod crank mechanism
Plunger Metering Pump with rod crank mechanism, harmonic plunger movement with positive return, flow rate regulation with manual control or servo-assisted.
The PD 80 plunger metering pump has been designed and constructed to meet the most varied metering demands of liquids and chemical reagents. This pump features simple and tested operating principles, yet it does not forgo the high metering precision that characterises all Sodi Scientifica pumps.
Its sturdy and compact structure assures high performance in heavy duty applications and makes its maintenance very straightforward.
Available in four main versions, two with head and valve body in PVC and two with head and valve body in AISI 316 stainless steel, differentiated based on maximum flow rate level.
