Our Services
We offer excellent after-sales service. Our products come with a 12-month warranty. We will do our best to resolve any quality issues until the customer is satisfied.
Customized Solutions
We can customize solutions according to customer needs, readily meeting their requirements for diaphragm vacuum pumps. We will formally notify the customer before production and confirm the design based on our samples.
Quality Control
We have a professional quality inspection team to ensure your products are of the highest quality. We inspect raw materials before production, conduct random sampling during processing, and perform 100% inspection before shipment.
High efficiency filtration
The filter element adopts the customized ultrafine fiber filter layer and agglomerating layer, and the filtration efficiency can reach 99. The filtered air liquid content is less than 5mg/m, which can fully meet the requirements of vacuum pump.
Small pressure difference
The vacuum protection filter is installed between the vacuum pump and the vacuum tube, so every 100mbar increase in the pressure difference will consume 20% more energy, the vacuum pump will work 20% more time, the cost of spare parts will increase accordingly, and the service life of the vacuum pump will be reduced by more than 30%. When the pressure difference exceeds 300mbar, the vacuum pump will continue to work and consume more energy.

The vacuum pump tubes for inlet is a device for improving, generating and maintaining vacuum in a closed space by various methods. It is developed with the latest international technology, so its quality is absolutely guaranteed, and it can almost achieve a high level of vacuum pumping effect. In addition to connecting one end of the exhaust pipe, the other end is blocked or connected to the bypass valve. This kind of pump has low center of gravity and good stability when running at high speed.
Application of Vacuum Pump Fittings
