The Longgu mechanical seal Roots blower adopts a new type of mechanical seal method, which is more reliable in sealing and almost free from leakage faults. Compared with ordinary Roots blowers, it is safer and more reliable. It can be used to transport flammable, explosive or toxic and harmful gases. The structure is simple, easy to maintain, compact, small in size, light in weight, and easy to use and maintain. Longgu mechanical seal Roots blower has a wide range of applications, including the transportation of flammable and explosive gases such as biogas boosting, gas transportation, and natural gas transportation. In addition, it can also be used in many industries such as sewage treatment, pneumatic transportation, powder material transportation, electricity, cement, etc., with a variety of specifications and models.

The Longgu mechanical seal Roots blower adopts mechanical sealing method, with good sealing performance, high reliability, and long service life. It can be used to transport flammable and explosive gases and has been widely used in many industries such as sewage treatment, flour, aquaculture, pneumatic conveying, cement plants, etc. Longgu mechanical seal Roots blower products have a wide range of air volume, dense grading, high pressure rise, and diverse specifications and models.


The mechanical seal Roots blower is a new product developed automatically by our company based on the advanced technical characteristics of various models of Roots blowers at home and abroad. The product research and development use advanced CAD assisted design and advanced processing technology to ensure the performance of the blower. It has been widely used in industries such as sewage treatment, flour, aquaculture, pneumatic conveying, electricity, and cement in the national economy. The product has a wide range of air volume, dense grading, and high pressure rise, with nearly 20 models and more than 100 specifications.
1. The Longgu mechanical seal Roots blower belongs to a type of fixed volume blower, which has no internal compression and can force gas transmission. The flow rate changes little with pressure changes;
2. The fan adopts a three bladed linear impeller with low noise and smooth intake and exhaust pulsation;
3. The fan impeller adopts a special curve design and production, with more reasonable meshing, less mechanical seal leakage, low energy consumption, and high efficiency;
4. Adopting various new structural designs, the overall structure is compact, small in size, aesthetically pleasing in appearance, and lightweight;
5. The fan adopts high-precision hard tooth synchronous gears, with low noise, long service life, and easy maintenance;
6. Sealed model, the transported gas is clean and not contaminated by oil and dust.
The sealing methods of Longgu Roots blower mainly include labyrinth seal, floating ring seal, mechanical seal, dry gas seal and other sealing forms. Mechanical seal Roots blower has high-performance, high reliability, and long-life containerized double end mechanical seal.
