What Are EODD Pumps?

Electric diaphragm pumps are engineered for energy efficiency and durability, and can be applied in various industries and specific applications.

Definition

A type of positive displacement pump that uses a reciprocating diaphragm driven by an electric motor to move fluid.

Core Principle

It combines electric motor reliability with the diaphragm's ability to handle sensitive, viscous, or abrasive fluids.

Key Characteristic

The pumped fluid is completely isolated from the pump's mechanical parts in a sealed chamber.
