How it works?

The micro diaphragm pump is an electric positive displacement pump, which realizes fluid transmission by changing the volume of the pump cavity through reciprocating motion.


Motor driven

DC motor provides driving force for pump head operation. The diaphragm seals the compression chamber off from the drive mechanism with nearly zero leakage. 


Diaphragm movements

The eccentric turns the rotational motion into the reciprocating motion of the diaphragm to move up and down and drive the fluid motion


Unidirectional flow

On the downward stroke, the diaphragm draws the medium in via the inlet valve. On the upward stroke, it forces the medium out of the outlet valve.

Different industry and technical applications benefit from the use of micro diaphragm pumps: it prevents media contamination and ensures excellent leak-tightness for media transfer. When used with gaseous media, it is resistant to moisture and condensate. When used with liquids, the diaphragm pump is self-priming and safe to run dry. Miniature diaphragm pumps can be maintenance-free for life, and have the advantages of small size, low noise, and low vibration.

Key Features About Our Pumps

Options We Can Offer

Hilintec innovative structured design and build-to-order management model can provide customers with more flexible customization options. Lets's begin to customize the pumps you need!

Different Motors

We can provide motor options with different performance, cost, and life span, such as brushed motors, brushless motors, etc.


Elastomers of different materials can meet the transmission requirements of different media, especially corrosion-resistant materials can achieve a longer working life.

Pneumatic Connectors

For different piping systems, different connectors such as hose connectors with different size, push-in connectors, internal thread connectors can be selected

Control Signals

Most product models support speed adjustment signals and start-stop control signals, which makes it easier to control flow and on-off. These signal specifications can be customized.

Flow Rates

In addition to changing the flow rate by adjusting the speed through the signal, the flow rate of the pump can also be customized through different eccentrics and changing the volume of the pump cavity.

All New Design

Our experienced R&D team supports further customized development for customers' special requirements through ODM/OEM and other methods
