Miniature Diaphragm Pumps

Foreach miniature diaphragm pumps are compact OEM pumps for liquid transfer, washing, circulation, waste aspiration, vacuum generation, and other fluid-handling functions in IVD analyzers, laboratory instruments, medical equipment, and automated fluidic systems. The range includes miniature liquid diaphragm pumps and miniature gas-liquid diaphragm pumps for different media and operating conditions.

Miniature diaphragm pumps are also commonly searched as micro diaphragm pumps or micro liquid pumps, depending on the application. Liquid-pump selection should consider working flow, pressure, self-priming conditions, tubing resistance, wetted-material compatibility, motor type and service life, and speed control and control interfaces. For systems where air may enter the tubing together with liquid, use a gas-liquid diaphragm pump and evaluate vacuum level, evacuation time, and system volume.

For liquid-only transfer, washing, reagent delivery, or circulation, select the Miniature Liquid Diaphragm Pump range. For waste aspiration, tubing evacuation, or applications where air and liquid may enter together, select the Miniature Gas-Liquid Diaphragm Pump range.
