Diaphragm Vacuum Pump

Suitable for when small size, high pressure and the ability to self-prime are key requirements.

Overview

Miniature diaphragm pumps use a reciprocating diaphragm driven by an eccentric motor to alternately expand and compress the pump chamber, enabling self-priming and dry-run capability. These compact units deliver high pressures (up to 10 bar) and vertical suction lifts while handling both liquids and gases with low pulsation and quiet operation. Their static sealing and absence of valves make them ideal for precision dosing, medical devices, and portable fluid systems

How does diaphragm pump work?

A diaphragm micro pump is a compact fluid handling device that uses a flexible diaphragm to move liquids or gases. The diaphragm flexes back and forth to create suction and pressure, allowing the pump to draw in and expel fluid through check valves.

This design offers several advantages:
• Self-priming capability, ideal for systems without pre-filled lines
• Dry-running possible without damage
• Precise, pulsed flow control
• Suitable for both gases and liquids

Diaphragm micro pumps are commonly used in medical equipment, portable analyzers, and applications requiring chemical resistance and maintenance-free operation.
