High-Speed Roots Vacuum Pump Operation - China Suppliers and Factory for Enhanced Vacuum Performance
01
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.
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
Independently produced and manufactured, it has over 40 vacuum-related patents, has been rated as a national high-tech enterprise and a science and technology enterprise, and has passed ISO9001 quality management system certification.
04
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.

Frequently Asked Questions
Q
What is the maximum suction rate available in the ZJ/ZJP series pump models?
A
The highest maximum suction rate in this series is 5000 L/S, offered by the ZJ-5000 model, making it suitable for large-scale industrial vacuum applications.
Q
Which model is most suitable for low-noise working environments?
A
The ZJP-30 and ZJP-70 models produce the lowest noise levels at ≤78 dB(A), making them the best choices for noise-sensitive environments or smaller-scale operations.
Q
What motor power is required for the ZJ-2500 and ZJ-5000 models?
A
The ZJ-2500 requires a 22 kW motor, while the ZJ-5000 requires a 37 kW motor. Both models operate at a speed of 2940 r/min and are designed for heavy-duty industrial use.
Q
How do I select the right model based on intake and exhaust pipe diameters?
A
You should match the pump's intake and exhaust pipe diameters to your existing pipeline specifications. For example, if your system uses 150 mm intake and 100 mm exhaust pipes, the ZJP-300 model would be the appropriate choice.
Q
What is the operating speed range across the ZJ/ZJP pump series?
A
The operating speed ranges from 1420 r/min (ZJP-30) to 2940 r/min (ZJ-1200, ZJ-2500, ZJ-5000). Most mid-to-large models operate at approximately 2880–2940 r/min for high-efficiency performance.
Q
Can these pumps be used in continuous industrial vacuum systems?
A
Yes, the ZJ/ZJP series pumps are engineered for continuous operation in industrial vacuum systems. With motor powers ranging from 1.5 kW to 37 kW and suction rates from 30 L/S to 5000 L/S, they cover a wide range of industrial vacuum requirements.
