Metering Pumps "HMS MF" Series are the ideal solution for low / middle dosing of chemicals. All control and setup parameters are available through a digital keyboard and they are displayed on a LCD backlit display.
Pump has: "Standby" input, "SEFL" input, "LEVEL" input and "Alarm" (contact) output. Note: "SEFL" not included.
Flow rate is determined by the stroke length and by the stroke speed. The stroke length is adjustable from 0 to 100% using the stroke length adjustment knob. However dosing accuracy is guarantee within an adjustment range from 30% to 100%.
Pump can work in 7 different ways:
Stroke Mode: Pump doses at a constant rate set in "SPH" (strokes for hour), "SPM" (strokes for minute) parameters set during program session.
Divide Mode: External pulses from a water meter are divided by a value set during program session. The pump doses with a rate determined by this parameter.
Multiply Mode: External pulses from a water meter are multiplied by a value set during program session. The pump doses with a rate determined by this parameter.
PPM Mode: Dosing rate is determined by pulses from a water meter on the base of set PPM, chemical product concentration (%) and quantity for each single stroke set during program session.
Batch Mode: Signal from an external contact starts the pump to dose the set quantity.
Volt Mode: Voltage from an external device drives the pump that doses proportionally using a minimum and maximum of strokes for minute set during program session.
mA Mode: Current from an external device drives the pump that doses proportionally using a minimum and maximum of strokes for minute set during program session.
