"HMS" series magnetic membrane batching pumps are ideal for small and medium dosing of liquid products.
The pump 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 the suction 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).
Flow rate is determined by the stroke length and stroking rate. The stroke length is adjustable from 0 to 100% using the stroke length adjustment knob. However repeatability is ensure within adjustment range between 30% and 100%.
