The ZJP2500 Small Roots Vacuum Pump delivers 2500L/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

Industrial Applications
Widely utilized in vacuum metallurgy (smelting, degassing, rolling), chemical processing (vacuum distillation, concentration, solvent recovery), food industry (vacuum packaging, freeze-drying), pharmaceutical manufacturing (vacuum drying, sterilization), electronic component production, and various other industrial sectors. Ideal for all processes requiring medium to high vacuum environments, particularly applications involving extracted gases with minor water vapor and dust content where clean vacuum conditions are essential.
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.
