Chemical Metering Pumps and Chemical Injection

Metering pumps are used  for chemical injection application and are used to pump chemicals at adjustable flow rates which are averaged over time. The delivery of fluids in precise adjustable flow rates is sometimes called metering. The term “metering pump” is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps.

In addition to being used for chemical injection and other solutions, metering pumps can be used for water. Many metering pumps are rated to be able to pump into a high discharge pressure, and are typically made to meter at flow rates which are continuous when averaged over time.

Metering pumps are provided with a maximum discharge pressure rating against which each model is guaranteed to be able to pump against. The pressure, temperature ratings and wetted pump materials are designed appropriately for each application.

Avoiding leakage at the packing or seal is accomplished by using diaphragm pumps for metering. Diaphragm pumps have a diaphragm through which repeated compression/decompression motion is transmitted. This motion changes the volume of a chamber in the pump head, therefore allowing air to enter and exit via check valves.

Some diaphragm pumps offer patented, heavy-duty gear reducer system for superior performance. Hydraulically actuated diaphragm minimizes diaphragm fatigue. Built-in hydraulic relief valve protects the pump. Stroke rate easily automated using variable-speed drive.
