ZJQ Gas circulation-cooled Roots Pump

Our design features a wide-body sealing surface and a large-channel cooling reflux structure, ensuring stable operation even under high differential pressure with minimal temperature increase.

We utilize advanced horizontal and gantry machining centers, along with precision equipment, to manufacture the end covers and pump bodies of our Roots vacuum pumps. These components are processed using five-axis simultaneous machining for exceptional precision. Our nine-axis, five-link CNC milling and turning center precisely shapes the rotor profiles, and our intelligent manufacturing equipment guarantees higher accuracy and interchangeability of parts.

Boke Vacuum employs German Schenck dynamic balancing machines for rotor balancing, achieving G1-class precision that results in low noise, low vibration, and minimal inertial forces, allowing for stable high-speed rotor operation. Additionally, we use an American Leitz coordinate measuring machine with a scanning head for 3D measurement of all components, ensuring processing accuracy and perfect interchangeability.

The shaft-side seals of our air-cooled Roots pumps utilize mechanical seals to completely eliminate oil leakage. Chamber seals can be customized with mechanical seals, lip seals, nitrogen seals, and more, ensuring reliable sealing with zero leakage.

Drawing on our practical experience, we offer various corrosion-resistant solutions tailored to your specific operating conditions. For instance, we apply electroless nickel-phosphorus alloy plating on flow parts or use stainless steel, duplex stainless steel, titanium alloys, Hastelloy, and other special materials in our manufacturing processes.
