ZJ &ZJP Roots Vacuum Pumps With 70–2,500 L/S Pumping Speeds For Industrial Vacuum Coating
1. Product Overview
The AIRIPA ZJ & ZJP Series Roots Vacuum Pump is an industrial vacuum booster designed to increase pumping capacity and improve gas removal in medium- and high-vacuum systems. Its precision-engineered, non-contacting twin-rotor mechanism provides continuous gas transfer without oil injection into the pumping chamber.
The series includes six models with nominal pumping speeds from 70 to 2,500 L/s and motor powers from 1.1 to 22 kW. Designed for integration with suitable backing pumps, these Roots vacuum boosters support industrial vacuum coating, metallurgy, heat treatment and other vacuum processes.
AIRIPA provides factory-direct supply, technical consultation and OEM/ODM services for industrial equipment manufacturers and vacuum system integrators.
2. Key Features & Benefits
High Pumping Speed
Nominal pumping speeds of 70–2,500 L/s support rapid gas removal and increased pumping capacity in compatible vacuum systems.
Precision Twin-Rotor Technology
Synchronized, non-contacting rotors provide continuous gas transfer while reducing internal mechanical wear.
Oil-Free Pumping Chamber
The pumping chamber operates without oil injection, helping minimize the risk of oil contamination in the process gas.
Reliable Continuous Operation
A robust mechanical structure supports industrial operation when the pump is used within its specified operating limits.
Low Vibration & Noise
Precision rotor design and non-contacting operation help reduce mechanical vibration and support stable performance.
Efficient Vacuum System Integration
Proper matching with a backing pump can improve overall pumping performance and system operating efficiency.
Compact & Durable Construction
The integrated mechanical design supports installation in industrial vacuum equipment and simplifies system integration.
Flexible Backing Pump Matching
Multiple models and recommended backing pump combinations accommodate different industrial vacuum requirements.
3. Working Principle
The ZJ & ZJP Roots vacuum pump uses two synchronized rotors rotating in opposite directions inside a pumping chamber. Gas enters through the inlet, is transported between the rotors and housing, and is discharged toward the exhaust without rotor-to-rotor contact.
As a vacuum booster, the pump operates with a suitable backing pump to maintain the required exhaust pressure. This combination increases pumping capacity within the system's intended operating pressure range.
