Electromagnetic Solenoid Dosing Pumps – Accurate Dosing & Easy to Adjust

Electromagnetic solenoid dosing pump is a type of dosing pump designed to deliver low-flow, low-pressure liquid in pipelines. It is driven by an electromagnetic and is considered one of the most popular and typical products among dosing pumps. Its design principle is "simple and practical," which means it has a simple structure, low energy consumption, accurate metering, and convenient adjustment, making it very popular in the industry. Reasonable and flexible internal design makes customization possible. We can provide solutions for you according to user needs and special working conditions to avoid the embarrassing modification of process design upon the unsuitability of product.

Working Principle

The electromagnetic push rod of the electromagnet is provided with a PTFE diagram. When the electromagnet is energized, the electromagnetic push rod pushes the PTFE diaphragm to discharge the liquid in the pump head of the dosing pump out of the dosing pump through the outlet valve. Then the electromagnet is curt off. The electromagnetic push rod and PTFE diaphragm return under the action of the spring. The liquid is sucked into the dosing pump through the inlet valve of the dosing pump to complete a working cycle.
