ZJP70 Small Roots Vacuum Pump
The ZJP70 Small Roots Vacuum Pump delivers 70L/S pumping speed in a compact, low-noise design, making it ideal for small vacuum systems. This rotary variable volume mechanical booster pump operates through synchronized reverse rotation of "8" shaped rotors within the pump cavity, effectively moving gas to achieve extraction. Characterized by high pumping rates and low motor power requirements, it requires a front pump for pre-pumping to reach specified vacuum levels before activation.

Key Features & Advantages
  • Friction-free operation with no lubrication required, ensuring oil-free pump cavity for clean vacuum output
  • Dual-leaf involute cycloid rotor profile with high-precision machining for smooth, quiet operation
  • Vertical gas flow design facilitates efficient discharge of dust and condensate from pumped gases
  • High-strength, symmetrical rotors with precise dynamic balance for stable, reliable performance
  • High-precision gears and imported bearings minimize vibration and noise levels
  • Advanced omni-directional three-dimensional water-cooling jacket effectively cools pump body, extending service life
  • Corrosion-resistant surface treatments available (shackles plating, Hastelloy, PTFE) for various corrosive environments
  • Compatible with liquid ring vacuum pumps, rotary vane vacuum pumps, and dry vacuum pumps to form complete Roots vacuum units

Frequently Asked Questions
Can I order a sample for performance testing?
Yes, sample orders are warmly welcomed. We also provide customized technical matching solutions based on your specific application scenarios.
What type of front-stage pump is suitable for matching with the ZJP series?
For general vacuum requirements, oil-sealed mechanical pumps are recommended; for processes with significant water vapor, liquid ring pumps are more suitable to prevent oil emulsification.
Is there a MOQ limit for this product?
No, the minimum order quantity is 1 unit, supporting both sample testing and small-batch procurement.
How long is the delivery time for mass production?
Standard delivery is 8-12 working days after deposit confirmation; urgent orders receive priority processing with potentially shortened lead times.
Can the product be customized according to special requirements?
Yes, we provide comprehensive OEM/ODM services, including customized inlet/outlet sizes, cooling methods, and control functions. Please share your specific requirements in advance.
What is the warranty period of the ZJP series Roots vacuum pump?
We provide a 1-year warranty covering manufacturing defects and component failures (excluding wear parts and damage from improper use).
How to handle faulty products during the warranty period?
Our products undergo strict quality control with a defective rate below 0.2%. For minor issues, replacements accompany your next order; for batch defects, we provide repair, replacement, or recall services as appropriate.
How to solve the problem of excessive noise during operation?
First, verify proper horizontal installation and rotor clearance; second, confirm appropriate front-stage pump matching. If issues persist, contact our technical support team for professional troubleshooting.
