High-Speed Roots Vacuum Pump Operation - China Suppliers and Factory for Efficient Vacuum Solutions
01
The accessories are precisely manufactured by imported processing centers, with strict control of the gaps between rotors and between rotors and the pump body, ensuring stable operation when the gap is less than 0.05mm
02
The spiral jacket cooling method ensures excellent heat exchange efficiency, fully guaranteeing the low-temperature lubrication performance of the lubricating oil, thereby extending the service life of gears, bearings and mechanical seals
03
The use of precision gears (5-level accuracy) for rotation and precision couplings for connection ensures the smoothness and accuracy of the pump's operation, with extremely low running noise.
04
A bypass valve is set inside, allowing the Roots vacuum pump and the preceding vacuum pump to almost simultaneously start under atmospheric conditions to shorten the pumping time.

Frequently Asked Questions
Q
What is the maximum suction rate available in the ZJ/ZJP series, and which model provides it?
The highest maximum suction rate in the ZJ/ZJP series is 5000 L/S, achieved by the ZJ-5000 model, which is driven by a 37 kW motor operating at 2940 r/min.
Q
What is the noise level range across the ZJ/ZJP pump series?
The noise levels range from ≤78 dB(A) for the smaller models (ZJP-30 and ZJP-70) up to ≤88 dB(A) for the largest model (ZJ-5000). Generally, noise increases proportionally with pump capacity and motor power.
Q
How do I select the right ZJ/ZJP model for my application?
Model selection should be based on your required suction rate (L/S), available pipe connection sizes (intake and exhaust diameters), acceptable noise level, and available motor power supply. Match these parameters against the specification table to identify the most suitable model for your system.
Q
What intake and exhaust pipe diameters are required for the ZJP-600 model?
The ZJP-600 requires an intake pipe diameter of 200 mm and an exhaust pipe diameter of 150 mm. Ensure your piping system matches these specifications for proper installation and optimal performance.
Q
What is the operating speed range for the ZJ/ZJP pump series?
The operating speed ranges from 1420 r/min (ZJP-30) to 2940 r/min (ZJ-1200, ZJ-2500, ZJ-5000). Most models in the mid-to-large range operate at approximately 2880–2940 r/min, which corresponds to standard high-speed motor configurations.
Q
Are the ZJP-30 and ZJP-70 models suitable for low-noise environments?
Yes. Both the ZJP-30 and ZJP-70 operate at a noise level of ≤78 dB(A), which is the lowest in the series. They are well-suited for applications where noise control is a priority, such as laboratory or light industrial environments.
