ZJ / ZJP Series High Performance Vacuum Pump Industrial Roots Vacuum Pump Low Wear

1. Product Overview

The ZJ & ZJP Series Roots Vacuum Pump, manufactured by AIRIPA, is an industrial-grade vacuum equipment designed to meet the demanding needs of various high-end manufacturing and research industries. As a boosted pump, it must be used in series with a foreline pump to enhance the pumping speed and vacuum level of the entire system. The ZJP model is equipped with a bypass valve and oil seal for enhanced functionality.

2. Outstanding Features

• Large Flow & High Boosting, Excellent Pumping Efficiency With precision rotor profile design, the pump boasts extremely high volumetric efficiency and strong boosting capacity in low-to-medium vacuum ranges. It can quickly establish a stable vacuum environment, significantly improving the overall production rhythm of your production line.
• Stable Vacuum Without Pulse, High Process Consistency The pump operates with uniform and smooth airflow, resulting in minimal vacuum level fluctuation and no impact pulse. It provides a highly stable vacuum environment, greatly improving the yield of precision components.
• Non-contact & Low Wear, Ultra-long Service Life The rotors operate without mechanical contact, leading to extremely low wear. The pump can run continuously for 24 hours in a steady state, featuring an extremely low failure rate to meet the uninterrupted production demands of industrial applications.
• Energy-efficient & Easy Maintenance, High Comprehensive Cost-effectiveness It features low power consumption and excellent energy efficiency. With a concise structure, it is easy to maintain and requires no frequent maintenance, greatly reducing the full-cycle operating costs of the equipment.
