Ease of use and maximum reliability
The PDM56 mechanical diaphragm metering pump, represents the evolution of the previous metering pump model PDM.
It 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.
Characterized by great simplicity the PDM 56 pump does not forgo the high metering precision that characterises all Sodi Scientifica pumps.
The maximum flow rate of this pump ranges from 6 to 38 l/h with a constant maximum pressure t all flow levels with three-phase motor.
Its sturdy and compact structure assures high performance in heavy duty applications and makes its maintenance very straightforward.
Manual Flow Regulation
Manual regulation when stationary or in motion. Diaphragm stroke length is regulated through a manual rotation of an adjustment graduated wheel with locking knob. The percentage flow rate is indicated on a printed analog scale.
Recommended accessories and spare parts
A number of accessories are available on request to allow the installer / maintainer to be independent for the first scheduled maintenance works. Included into the initial kit of recommended accessories and spare parts you can find: 4.5 meters PE hose, AS valve, spare diaphragm, set of head seals and bottom valve with filter.
