China Suppliers Factory FOR YOU Air-Cooled Roots Vacuum Pump - High Performance, 150 mbar Vacuum Degree

Our high-performance vacuum pumps are engineered to achieve an impressive working vacuum degree of 150 mbar, directly operating against the atmosphere. This exceptional performance makes them a top choice among manufacturers in China.
Designed with a unique structural framework, these pumps can withstand high pressure differences and compression ratios without risk of overheating or overloading, ensuring reliability and efficiency in demanding environments.
Each model in our series features QT500 high-strength ductile iron rotors, boasting a tensile strength of 500 MPa and an elongation rate of 15%. As a leading supplier and factory in the industry, we are committed to providing durable and efficient solutions tailored to meet the needs of our global customers.

    Product Characteristics

    01

    The special structural design ensures that the pump will not overheat or overload when operating under high pressure difference and high compression ratio

    02

    💬 Frequently Asked Questions
    Q What is the maximum suction rate available in the ZJQ pump series?
    The highest maximum suction rate in the ZJQ series is 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 determined based on the actual working pressure difference. Each model offers a rated power range (e.g., ZJQ-1200: 15~132 KW), and the appropriate motor is selected according to the specific operating conditions.
    Q Will the water consumption change with different pressure differences?
    Yes. Water consumption varies depending on the actual working pressure difference. Different operating pressure differences will require different cooler configurations, which directly affects the amount of water consumed during operation.
    Q What are the intake and exhaust diameter options across the ZJQ series?
    The intake and exhaust diameters range from 125 mm (ZJQ-300) up to 400 mm (ZJQ-5000). Mid-range models such as ZJQ-1200 use 300 mm, while ZJQ-2500 and ZJQ-3750 both use 350 mm diameters.
    Q What operating speed (rpm) do the ZJQ pump models run at?
    Most ZJQ models operate at 1470 rpm. The ZJQ-300 runs at 1480 rpm and the ZJQ-600 at 1460 rpm, with the remaining models all standardized at 1470 rpm for stable and efficient performance.
