Metering Pump
Metering Pump
A metering pump is a specialized positive displacement pump with a flow rate that can be adjusted steplessly within the 0-100% range. It is particularly suitable for conveying liquids, especially corrosive ones. Also known as a dosing pump or proportional pump, it is widely used in various chemical dosing systems, earning it the name chemical dosing pump. Metering pumps are extensively applied in water treatment, petrochemicals, pharmaceuticals, and food production industries.
