Energy-Saving Screw Vacuum Pump JZN-880

The JZN-880 Permanent Magnet VFD Energy-Saving Screw Vacuum Pump is a high-efficiency, low-power-consumption vacuum equipment customized for all industrial production scenarios, adopting cutting-edge permanent magnet variable frequency drive (VFD/VSD) technology. It provides stable, continuous vacuum environment for long-cycle industrial processes while drastically cutting electricity cost.

Core Advantages

1. Outstanding Energy Saving Performance

The pump automatically adjusts motor rotation speed to lock the preset vacuum pressure. Compared with traditional fixed-speed screw vacuum pumps, it achieves over 30% electricity saving. It only outputs full power when production needs rapid air evacuation; during standby/idle stages, it reduces speed intelligently to eliminate unnecessary power waste, greatly lowering factory operating expense.

2. Premium & Reliable Full Set Core Components

1. 1. Integrated Direct Drive Screw Host:Built-in IE5 high-efficiency permanent magnet motor with direct drive structure, no transmission loss. Features strong torque and ultra-fast response speed, meeting top international energy efficiency standard IE5.
2. 2. Large Axial Flow Cooling Fan: Low power consumption, rapid heat dissipation to keep unit temperature stable, support 24h non-stop operation with eco-friendly low power loss.
3. 3. Full Soundproof Enclosure: Internal high-density sound absorption foam + thick metal shell effectively reduce running noise, no extra sound insulation construction needed for pump room. All parts are front-access for convenient inspection and routine maintenance.
4. 4. Integrated VSD Variable Frequency Driver: Whole machine integrated frequency converter, plug-and-play installation without complicated wiring. Factory pre-optimized operating parameters to maximize overall energy efficiency.
5. 5. Microcomputer Intelligent Controller: Centralized automatic control system, real-time display of vacuum degree, current, temperature and running status. Reminds users of maintenance cycles, and triggers automatic safety shutdown once any fault occurs to protect the whole unit.
6. 6. Special Automatic Inlet Control Valve: Self-regulate opening size to guarantee uniform oil injection and full rotor lubrication, reduce oil leakage and oil consumption effectively.
7. 7. High-Efficiency Oil-Gas Separator: Advanced separation design limits residual oil content in exhausted air to ≤3ppm, service cycle reaches 5000 hours, fewer replacement times and lower consumable cost.
8. 8. Patented Rotary Cantilever Air Filter: Unique rotary cantilever structure, easy to disassemble and clean. High dust filtration efficiency extends filter service life and protects internal screw rotor from abrasion.

3. Stable & Consistent Vacuum Output for Continuous Production

• Ultimate vacuum degree: 30 Pa
• Rated pumping speed: 14.6 m³/min (876 m³/h) It maintains steady vacuum pressure under long-time continuous working condition, avoids vacuum fluctuation that affects product yield, stabilizes whole production line and cuts long-term equipment maintenance cost.

Application Scenarios

Suitable for packaging industry, plastic molding, chemical processing, wood drying, electronic component processing, printing and other industrial fields requiring continuous vacuum evacuation.
