"CMS Digital" series, foot mounted solenoid driven metering pump is suitable for small and medium dosing amount of additive.
"CMS Digital" working mode is intermittent: a magnetic field is created each time a pulse reaches the magnet. The magnetic field pushes the piston. A diaphragm (fixed on the piston head)compresses the liquid into the pump head. The liquid gets out through the delivery valves while the suction valves close. When the pulse ends, a spring takes back the piston and the diaphragm. The vacuum created by the diaphragm movement takes the liquid inside the pump head from thesuction valve, while the delivery valve is closed. The pump capacity is proportional to the number of strokes and to the pump head internal volume (Single Stroke Injection Quantity).Solenoid driven dosing pumps can operate without liquid without problems to its assemblies.
Box: "CMS Digital" series dosing pumps are assembled in IP65 (PP and glass fiber) plastic material boxes. Installation is wall mounted by means of two screws at a distance of 152 mm.
Electronic Circuit: The electronic circuit is made of proved quality components. It provides the necessary electrical pulses to the magnet.
Electro-Magnet: The electro-magnet with class H (180°C) copper winding, driven by the electronic circuit, gives the necessary push to the piston and the diaphragm. Piston stroke length varies from 0,7 to 1,7mm, according to the pump dimension type (pressure/output).
Diaphragm: PTFE diaphragms used in the "CMS Digital" series pumps assure good chemical compatibility and mechanical resistance.
Pump Head: "CMS Digital" series Pump Head diameters are: ø22, ø32, ø44, ø58, ø64. The pump head works as a dosing chamber, the suction valve, delivery and manual out gassing valves are inside it. The purpose of the manual out gassing valve is to help the priming of the pump during installation.Pump head is made in PP and upon request PVDF.
