Metering pumps deliver precise, adjustable flow rates to move a measured volume of liquid over a specified time. Metering pumps can pump water, but they’re often reserved for pumping chemicals solutions or other fluids. Various types of pumps can be equipped to be metering pumps, but to avoid leakage at seals, especially when the liquid is toxic, noxious or otherwise dangerous, chemical metering pumps are typically diaphragm pumps.
Liquid does not penetrate the diaphragm that provides the pumping action through repeated compression and decompression, so the fluid inside the pump is sealed off from the outside. The chemical metering pumps we offer are typically used for process and agricultural industries, and are available for high and low pressure applications with manual and electronic stroke control.
