Product Overview: Redefining Industrial Vacuum
At Ever-Power, we have revolutionized the traditional booster pump with our latest High-Performance Roots Pumps. The ZJ-A and ZJP-A series represent a significant leap forward in vacuum technology. By integrating a permanent magnet variable frequency water-cooled vacuum motor, we have retained the robust pumping capabilities of the original Roots design while eliminating its historical weaknesses.
This is not just a pump; it is a comprehensive vacuum solution designed for the modern "Green Factory." Whether you are operating in the pharmaceutical sector requiring strict containment or the semiconductor industry needing precise pressure control, this series serves as the ideal Roots Vacuum Pump for Industrial Use.
1. Absolute Zero Leakage
The elimination of dynamic seals completely removes the risk of oil leakage or gas escape. The permanent magnet motor and the Roots Blower Vacuum Pump body form a fully enclosed, hermetically sealed space after installation. This achieves true zero leakage, protecting both your workforce and the environment.
2. Intelligent Variable Frequency
Equipped with advanced variable frequency drives (VFD), these pumps allow for precise rotational speed control based on real-time factory workload. This adaptability ensures your Vacuum Systems with Roots Pumps operate at optimal capacity without energy waste.
3. Energy Efficiency Level 1
High efficiency is at the core of the permanent magnet design. These motors approach the national Level 1 energy efficiency standard, significantly lowering operational costs compared to traditional asynchronous motors.
4. Compact Footprint
The direct-drive water-cooled motor design significantly reduces external dimensions. This space-saving architecture allows for easier integration into skids and tight facility layouts, solving installation headaches common with Heavy Duty Roots Blower Pumps.
5. Reliable Start-up
Variable frequency starting (requires a frequency converter) eliminates the massive in-rush current spikes associated with direct-on-line starts, ensuring grid stability and mechanical reliability of the rotors.

The Perfect Match: Dry Screw Backing Pumps
A Roots pump is a booster; it cannot exhaust directly to the atmosphere (unless it is a specialized ZJQ type). To maximize the capabilities of the ZJ-A/ZJP-A series, selecting the right backing pump is crucial. For modern "Oil-Less" applications, we recommend pairing these boosters with our Dry Screw Vacuum Pumps.
Why Go Dry?
- ✓
Solvent Recovery: In the Roots Vacuum Pumps for Chemical Industry, dry screw pumps allow for the condensation and recovery of valuable solvents at the exhaust, which would otherwise be contaminated by oil. - ✓
Zero Contamination: The pumping chamber is entirely free of oil or water. This creates an Oil-Less Roots Vacuum Pump system ideal for pharmaceutical drying and semiconductor processing. - ✓
Low Maintenance: Without oil to change or filters to clog, maintenance cycles are significantly extended, lowering the Total Cost of Ownership (TCO).
How to Select the Right Roots Pump
Choosing between a Standard, Magnetic Drive, or Permanent Magnet Roots pump depends on your specific application needs.
Choose Standard (ZJP) When:
- Budget is the primary constraint.
- The process gas is non-toxic and non-corrosive.
- Standard maintenance intervals are acceptable.
- General Roots Vacuum Pump for Manufacturing Industry use.
Choose Magnetic Drive (ZJPC) When:
- Handling toxic, flammable, or radioactive gases.
- Zero shaft leakage is a safety requirement.
- You need to eliminate shaft seal maintenance.
Choose PM Variable Freq (ZJP-A) When:
- Energy efficiency is a top priority (Level 1).
- Installation space is limited (Compact design).
- Process load varies significantly (Variable Frequency control).
- Zero leakage is required (Canned motor).

Frequently Asked Questions (FAQ)
1. What is the main advantage of the Permanent Magnet motor in these pumps?
The permanent magnet synchronous motor (PMSM) offers higher efficiency (Level 1 standard) compared to traditional induction motors. It also allows for a more compact design and precise variable frequency control, which optimizes power consumption based on the actual vacuum load.
2. Does the ZJP-A series require a separate cooling water system?
Yes, the motor is water-cooled to maintain compact dimensions and high efficiency. You will need a supply of cooling water (typically 8-10 L/min depending on the model) connected to the motor jacket. This ensures stable operation even in hot industrial environments.
3. Can I replace my existing Roots pump with this new ZJ-A model?
In most cases, yes. The ZJ-A series is significantly more compact than traditional pumps of the same pumping speed. However, because it uses a frequency converter for starting and operation, you may need to upgrade your electrical control panel. Our engineering team can assist with the retrofit design.
4. What is the difference between ZJ-A and ZJP-A?
Generally, the nomenclature refers to the specific configuration of the Roots blower. The ZJP-A typically includes an internal overflow valve (bypass valve) which allows the pump to start at higher pressure differentials without overloading, whereas the ZJ-A might be a standard booster requiring careful pressure staging. Please check the "Max Diff" in the performance table.
5. Is this pump suitable for "Two-Stage Roots Vacuum Pump" systems?
Absolutely. These pumps are designed to act as the booster stage. They can be backed by another Roots pump (multi-stage roots) or a primary backing pump like a screw pump or rotary vane pump to achieve deep vacuum levels (10⁻² Pa or lower).
