High-Performance FORYOU Air-Cooled Roots Vacuum Pump - China Suppliers and Factory with 150 mbar Vacuum Degree
01
The composite sealing structure technology completely solves the emulsification and leakage problems of vacuum pump oil, making it more stable and reliable.
02
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
03
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.
04
High-strength, high lateral force precision bearings from fully imported (SKF/NSK) are selected and lubricated by splash lubrication, which can greatly extend the pump's service life.

Note: The motor power of the pump, the heat exchange area of the cooler, and the water consumption are determined based on the actual working pressure difference. Different pressure differences require different motors and coolers, and the water consumption will also vary.
💬 Frequently Asked Questions
Q
What is the maximum suction rate available in the ZJQ pump series?
The ZJQ pump series offers a maximum suction rate of up to 5000 L/S, available in the ZJQ-5000 model, making it suitable for large-scale industrial vacuum applications.
Q
What is the limiting pressure for all ZJQ pump models?
All models in the ZJQ series share a uniform limiting pressure of 15,000 Pa, ensuring consistent performance across the entire product range.
Q
How is the motor power determined for a specific ZJQ pump model?
The motor power is not fixed — it is determined based on the actual working pressure difference of your application. Each model offers a rated power range (e.g., ZJQ-1200: 15~132 KW), and the appropriate motor is selected accordingly.
Q
Does the cooler specification vary between different operating conditions?
Yes. The heat exchange area of the cooler and the associated water consumption are both dependent on the actual working pressure difference. Different operating conditions will require different cooler configurations.
Q
What are the operating speeds (rpm) of the ZJQ pump models?
The operating speeds are very close across all models, ranging from 1460 to 1480 rpm. Specifically: ZJQ-300 at 1480 rpm, ZJQ-600 at 1460 rpm, and ZJQ-1200 through ZJQ-5000 all operate at 1470 rpm.
Q
What intake and exhaust diameter should I expect for larger ZJQ models?
Larger models feature wider port diameters to handle higher flow rates. The ZJQ-2500 and ZJQ-3750 both use 350 mm diameters, while the ZJQ-5000 uses a 400 mm diameter for maximum throughput.
