D25 is a kind of mini diaphragm gas pump for vacuum and compressor. It has pollution-free transmission feature. This model is maintenance-free and allowing the medium to contain water vapor. This diaphragm gas pump can operate continuously at maximum load. According to different media requirements, EPDM elastomer and FKM elastomer options can be provided.

 

Diaphragm Gas Pump with Compact Size

This product weighs about 80g with an overall size of about 68*35*56mm. It has a very compact size. It can be installed on the back panel of the device through flexible mounting feet. The installation direction will not affect the work of this type of pump, so it can provide very flexible installation options.

 

Special Brushed DC Motor

This model is driven by high-quality brushed motor which has the advantages of long lifetime, low interference, low energy consumption, high reliability, etc. Generally speaking, people think that the lifespan of brushed motors is difficult to compare with brushless motors. However, this model uses a long-life brush motor, which can provide a motor life similar to that of a BLDC motor. At the same time, it also has a lower cost and a more simplified structure.

 

Excellent Gas Tightness 

The specially designed double sealing structure can ensure the good air tightness of the product. According to user requirements, the air tightness can be specially tested and a corresponding report can be issued. Good airtightness makes it can be used to transmit high-value or hazardous gases. It can also be used in occasions where precise analysis of gas composition is required.

 

Industrial-grade Reliability 

In response to industrial-grade reliability requirements, we have designed a special test process for possible load conditions. Therefore, no matter what load the product actually works under, its actual service life can reach and exceed its nominal service life. If the actual working load is less than the nominal maximum load, its life can be further extended. Therefore tt can operate without stopping for a long time under the maximum load. The product has passed the life test under the maximum load, and can promise to reach the nominal life under various loads.

 

Long Service Life 

Equipped with a high-quality brushed DC motor, using high-performance elastomers, it can provide a service life comparable to a brushless motor pump. In addition to the motor, elastomers and bearings also have a vital impact on the life of the pump. We have also carried out aging tests on the life of the above parts, which can ensure that the life of the whole machine can reach and exceed the nominal level. For applications requiring longer life and higher reliability, we also provide D23 miniature diaphragm gas pumps with similar performance as an option.

 

Elastomer Options

Its standard product uses EPDM rubber elastomer widely used in the industry. This material has good corrosion resistance to common gases, and has the advantages of long life, high reliability and limited cost. According to different media requirements, EPDM elastomer and FKM elastomer options can be provided. Compared with EPDM, FKM can provide better corrosion resistance and higher working temperature.

Pump Head Options

Glass fiber reinforced nylon is a high-performance engineering plastic, which has good mechanical properties and chemical compatibility. For applications that transmit special media components, in addition to providing additional elastomer options, we can also customize special pump head materials, such as PPS and PTFE as customized options. Flexible pump head material options can meet a wider range of application needs
