Dosing Pumps Piston-driven
For a low-cost dosage of liquids
Working principle
These are piston-driven pumps with alternating motion. The flow rate is adjustable even in motion and modifies the piston displacement. The variation is linear and adjustable from 0% to 100%. They work manually through a handle with direct reading of the stroke and the flow proportion.
The mechanism is composed by a reduction gear, a crown gear and a screw conveyor. An off-center with running wheels causes the movement of a glide placed on the piston.
The piston comes back to their initial position by an oiled mould within an aluminum crankcase.
The heads of the pumps are composed by ball-valves, with easy access, and automatic Viton joints.
The pumps and gear are assembled with an elastic coupling.
