Diaphragm Dosing Pumps

Accurate dosing with a gentle pulsing motion, suitable for a variety of applications.

Designed to handle thick, viscous liquids Diagram pumps have a gentle pulsing motion that can be sped up or slowed down according to application. They work with a single diaphragm to create a chamber to draw liquid in and push it out through the pump. This enables a consistent, repeatable injection of a precise dose of liquid or chemical into a process line or system.

Diaphragm Dosing Pumps are suitable for corrosive, abrasive chemicals, chemical treatments or chemical additions.
