Miniature Diaphragm Vacuum Pumps for Sale Online


What is a Micro Diaphragm Vacuum Pump

Micro diaphragm vacuum pumps are often referred to as small vacuum pumps because of their small size. Micro diaphragm vacuum pump means: it has a suction nozzle and an exhaust nozzle, which can continuously form vacuum or negative pressure at the inlet; a slight positive pressure is formed at the exhaust nozzle; the working medium is mainly gas. It is a compact instrument.

These micro vacuum pumps are suitable for many applications. We offer high quality pumps for a variety of medical and non-medical applications.

We can prototype almost any type of miniature diaphragm pump! With the help of our expert engineers, product development, state-of-the-art design lab and machine shop, we can help you quickly. Contact us for more offers.


The Benefits of Choosing a Miniature Diaphragm Pump

The micro-diaphragm pump will not pollute the working medium, and has the advantages of small size, low noise, maintenance-free, and can run continuously for 24 hours. Therefore, the micro-vacuum pump is used as a power device and is widely used in gas sampling, gas circulation, vacuum adsorption, and accelerated filtration. It has been widely used in medical, health, scientific research, environmental protection and other fields.


Because the operation of the micro-diaphragm pump is relatively stable and has a long working time, it can run continuously for a long time, and the current passing through it under strong pressure is relatively small, and it is resistant to high temperature, corrosion, and noise. The reasonable internal structure reduces the wear of the pump body itself.

Long working life

The lifespan problem is the soft underbelly of many pumps. Due to the lack of performance or materials, products with short pump lifespans exist, while micro-diaphragm pumps have a longer lifespan, and the motor lifespan can even reach more than 10 years. Ordinary products are far less than 10 years old. Of course, regular maintenance is required during this period to ensure the normal operation of the equipment.

Energy efficient

The micro diaphragm pump has the effect of energy saving. It can be clearly seen in use that the power consumption of the micro diaphragm pump is relatively small, much less than that of ordinary products.
