Dosing Pumps

Dosing pump
the metering pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. It features a high level of repetitive accuracy and is capable of pumping a wide range of chemicals including acids, bases, corrosive or viscous liquids and slurries.
The pumping action is developed by a reciprocating piston which is either in direct contact with the process fluid, or is shielded from the fluid by a diaphragm. Diaphragms are actuated by hydraulic fluid between the piston and the diaphragm.
Metering pumps are generally used in applications where one or more of the following conditions exit:
low flow rates in mlhr or gph are required
high system pressure exists
high accuracy feed rate is demanded
dosing is controlled by computer, microprocessor, dcs, plc, or flow proportioning
corrosive, hazardous, or high temperature fluids are handled
viscous fluids or slurries need to be pumped
