BODENFLO Miniature Diaphragm Pumps Workshop Display
A micro diaphragm pump is a compact and efficient device engineered for precise fluid transfer. It utilizes a flexible diaphragm and an eccentric wheel to produce the pumping action, making it ideal for handling a variety of fluids. The diaphragm is a flexible membrane that is pushed and pulled by a mechanical actuation, creating a vacuum that draws fluid into the pump chamber and then expels it. These pumps are valued for their ability to handle a variety of fluids, including gases and liquids, with precision and consistency.
The micro diaphragm pump operates through a motor-driven eccentric wheel that moves the diaphragm. This motion changes the volume of the pump chamber, creating a suction and discharge cycle that continuously moves fluid.
There are several types of micro diaphragm pumps, each designed for specific applications:
Micro diaphragm pumps are renowned for their compact design, lightweight construction, and exceptional performance. Engineered for optimal efficiency, these pumps offer the advantage of oil-free operation, ensuring clean and contamination-free handling of various media. Their low power consumption and high-performance capabilities make them the preferred choice for OEM solutions, particularly in handheld and portable equipment. The integration of cutting-edge technology and adherence to stringent quality standards further enhance their appeal across diverse applications.

Micro diaphragm pumps are typically composed of an inlet and an outlet, connected by a reciprocating diaphragm. As the diaphragm moves back and forth, it generates a vacuum at the inlet and pressure at the outlet. This dual-action mechanism allows the pump to serve various applications requiring both pressure and vacuum. Here’s how this unique design can be utilized:
Application: In laboratory automation, simultaneous pressure and vacuum control can be used for precise fluid handling, such as in liquid dispensing and sample preparation.
Benefit: Enables complex processes with high precision and repeatability.
Environment: Often found in medical laboratories, research facilities, and pharmaceutical manufacturing.
Application: Utilized for pushing fluids through filtration systems, supplying pressure in hydraulic systems, or inflating devices.
Benefit: Provides controlled and consistent fluid flow.
Environment: Common in industrial manufacturing, water treatment, automotive, and healthcare equipment.
Application: Used for creating a vacuum in suction systems, vacuum packaging, or evacuating air from sealed environments.
Benefit: Enables processes that require the removal of air or gases, ensuring a controlled environment.
Environment: Typical in food packaging, medical suction devices, and semiconductor manufacturing.
Application: Some pumps allow switching between pressure and vacuum modes, catering to applications that require both functionalities at different stages.
Benefit: Enhances flexibility and adaptability in handling various tasks within a single system.
Environment: Ideal for multifunctional laboratory equipment, process automation, and specialized industrial machinery.
