A Better, Faster Way to Source Pumps

Dosing Pumps

What is a dosing pump?

A pump designed to deliver a set amount of a substance at regular intervals. They are also referred to as metering pumps.

Most dosing pumps use one of three different types of pumping mechanisms — plunger pumps, piston pumps, or diaphragm pumps. Each are positive displacement pumps that contain a chamber in which fluid is captured and subsequently released through an outlet valve. The flow rate is adjusted by varying the stroke length, pump speed, or both.

Where are they used?

The pump is used throughout many sectors of industry. The most common application is to move chemicals for water treatment, in municipal water and wastewater plants. They are also used to treat cooling tower and boiler feed water in industrial plants and commercial buildings, and to treat commercial swimming pool water.

For example, in the food and cosmetic industries, having a network of dosing pumps enables the operators to closely regulate and adjust the levels of ingredients that go into a mixture. They are also used in all kinds of textile, chemical treatment, medical, and industrial applications.
