A dosing pump is a positive displacement pump that is designed to inject a chemical or any other substance into the flow of water, gas or steam. Dosing pumps are typically small and provide an extremely precise flow rate for maximum control. They are applied to a wide range of industrial applications, from wastewater treatment to food processing.

How does a Dosing Pump work?

Dosing pumps also known as metering pumps are available in a variety of types and provide many years of reliable and efficient operations. In most dosing applications, the accuracy of dosing is very important. The operation of a dosing pump is based on the principle of a positive displacement pump.

The major part of these pumps is a valve that will suck the chemical liquid from the chemical tank to the pump. The pumps are built with a switch that gives an alarm when the chemical liquid has decreased. With the use of a piston or plunger, the dosing pump forces the fluid from the inlet to the outlet of the pump.

What is the function of a Dosing Pump & where it is used?

As mentioned above the chemical injection package serves the purpose of injecting a precise dose of chemicals accurately into a system with the required back pressure, either continuously or intermittently. Pulsafeeder has the Pulsa and PulsaPro Series hydraulic diaphragm pumps that are a benchmark of safety, reliability, accuracy and efficiency. It is primarily used in the Oil & gas, Base Chemicals, Speciality Chemicals, Agro Chemicals, Water & Wastewater, Refinery, Petrochemicals, Power and Chemicals industry.
