Dosing Pumps
A dosing pump is an electromagnetic diaphragm pump that delivers a chemical into a line or tank in a set amount at precise intervals.
It is used for pool chlorine and pH dosing, water treatment, boiler feed water conditioning and process chemicals. The product range includes 20 W, 100–240 V AC models with PVDF heads.
Main Applications
- Pool chlorine and pH dosing
- Water treatment and softening
- Boiler feed water conditioning
- Cooling tower chemicals
- Process chemical dosing
- Disinfection systems
