Dosatron – Non-Electric Proportional Dosing Pumps
Benefits of Using a Dosatron
Dosatron pumps reduce chemical waste, save energy, and keep the water supply consistent.
Because they use only water pressure they can operate anywhere, even without electricity. Their simple design means less maintenance and faster startup
How Does a Dosing Pump Work?
Dosatron is the original inventor of the non-electric proportional dosing pump since 1974.
Dosatron technology is a passive volumetric dosing pump based on a water driven hydraulic motor piston pump activated only by pressure and flow of water without any electricity or any measuring device.
Such a pump is composed of two main elements: a passive water driven hydraulic piston and a dosing piston.
How is the injection rate controlled?
A non-return suction valve opens during the suction in the additive pipe and it closes during the injection and mixing phase.
The dosing seal this vacuum by sealing the dosing body and the dosing piston. The dosing seal serves as a pressure valve (when lowering).
The metering piston therefore injects a fixed volume of additive at each cycle and acts as a reciprocating piston.
The dosing piston will inject the defined volume of additive in proportion to the volume of water passing through the water-powered piston. This volume of additive is manually adjustable by adjusting the capacity of the dosing body.
The principle of operation thus ensures a constant and continuous dosage proportional to the water flow, independent of variations in water flow and pressure.
How is the additive mixed?
The injection of the additive into each volume of driving water in the mixing chamber allows a continuous and homogeneous downstream of the dosing pump.
The dosing piston therefore continuously injects a fixed volume of additive and acts as a reciprocating positive displacement piston.
The dosing piston will inject the set volume of additive in proportion to the volume of water passing through the water driven piston. This volume of additive is manually adjustable by adjusting the capacity of the dosing body.
Therefore, the operating principle ensures constant dosing, independently of the variations in flow rate and pressure of the water. The injection of the additive is proportional to the water flow rate.
