Elevate your industrial vacuum capabilities with the Ever-Power Integrated Vacuum Unit. This advanced system synergizes the high pumping speed of a ZJ Series Roots Vacuum Pump (Main Pump) with the robust, oil-free reliability of an LGB Series Dry Screw Vacuum Pump (Backing Pump). Designed for demanding B2B applications, this turnkey solution delivers exceptional high-vacuum performance (up to 0.5 Pa) while maintaining a completely dry, clean processing environment.Meets the needs of numerous applications including lithium batteries, semiconductors, and coating.
What is an Integrated Roots-Screw Vacuum Unit?
The Integrated Vacuum Pump Unit is a pre-engineered vacuum package that combines two technologies to achieve performance levels that a single pump cannot reach.
- The Main Pump (ZJ Roots Blower): Acts as a booster. It does not compress gas against the atmosphere but "blows" gas from the inlet to the backing pump, significantly increasing pumping speed at low pressures.
- The Backing Pump (LGB Dry Screw): Takes the pre-compressed gas from the Roots pump and compresses it to atmospheric pressure for exhaust. Its unique dry screw design ensures no oil backstreaming.
By integrating these systems, the JZJLGB series provides higher vacuum levels, larger pumping speeds, and superior energy efficiency compared to using a screw pump alone.
Why Choose the Integrated Unit?
1. Ultimate Vacuum: 0.5 Pa
While standalone screw pumps typically reach 1-50 Pa, our integrated unit achieves 0.5 Pa. This deep vacuum is critical for high-purity distillation, freeze drying, and semiconductor processes.
2. 100% Oil-Free System
Both the Roots main pump and the Screw backing pump operate without oil in the gas path. This means zero contamination of your process gas and easy, pure solvent recovery at the exhaust.
3. Optimized Efficiency
The unit is skid-mounted with optimized piping and control logic. The Roots pump engages at the correct pressure, reducing total energy consumption while maximizing throughput.
Primary Applications
The JZJLGB Integrated Unit is the standard-bearer for industries requiring clean, high-vacuum environments:
- Chemical & Pharmaceutical: Solvent recovery, distillation, crystallization, and drying processes where oil contamination is prohibited.
- Semiconductor: CVD, Etching, and wafer handling processes requiring rapid pump-down times.
- Electric Grade Materials: Production of lithium battery electrolytes and high-purity capacitors.
- Coating Industry: PVD/CVD coating equipment requiring stable high vacuum.
How to Select Your Unit
Choosing the right Roots-Screw package depends on your process load:
- Calculate Flow: Determine the maximum gas load (m³/h). The main pump (Roots) dictates the peak speed.
- Target Vacuum: If you need pressures below 1 Pa, this unit is essential. If rough vacuum (>100 Pa) is sufficient, a standalone screw pump might suffice.
- Condensable Vapors: For wet processes, ensure the "Dry Screw" backing pump is configured with appropriate purge gas (nitrogen) settings, available on all JZJLGB models.
Voice of the Customer
"The integration of the Roots blower with the LGB screw pump has doubled our distillation throughput. The skid-mounted design made installation seamless in our existing plant layout."
- Technical Director, API Manufacturing Plant (India)
"We were struggling with oil back-streaming in our old rotary vane systems. Ever-Power's JZJLGB unit solved this instantly. Achieving 0.5 Pa cleanly has improved our coating quality significantly."
- Plant Manager, Optical Coating Facility (Germany)
Frequently Asked Questions (FAQ)
1. Why use a Roots pump with a Screw pump?
The Roots pump acts as a booster. It significantly increases pumping speed at low pressures (high vacuum) where the screw pump's efficiency might drop. The Screw pump then discharges the gas to the atmosphere. This combination gives you the "best of both worlds": high speed and high vacuum.
2. Can this unit run continuously?
Yes, the JZJLGB series is designed for 24/7 industrial operation. The integrated cooling systems ensures thermal stability.
3. Is the unit compatible with corrosive gases?
Standard models are suitable for general chemicals. For highly corrosive environments, we offer models with anti-corrosion coatings (Ni-P) or special materials (like Hastelloy) for the wetted parts.
4. What maintenance is required?
Since there is no oil in the pumping chamber, maintenance is minimal. You primarily need to check the gear oil and bearing grease levels periodically. There are no oil filters or oil mist separators to replace constantly.
5. Does the unit come skid-mounted?
Yes, the unit is delivered as a complete skid-mounted package, including the Main Pump, Backing Pump, interconnecting piping, base frame, and optional control panel, ready for installation.
