Shanghai Zenix Vacuum Coating Technology Co., Ltd. is a China-based Vacuum Pumps manufacturer with nearly 40 years of experience in vacuum coating equipment. Our vacuum pump range is engineered to support the demanding evacuation and process requirements of PVD hard coating, decorative coating, and functional coating systems. We supply pumps that form the critical foreline stage, ensuring rapid pump-down, stable base pressure, and reliable operation across continuous production cycles.
As a dedicated Vacuum Pumps supplier, we focus on mechanical pump / foreline pump solutions that integrate directly with our coating machines and can also be specified for existing vacuum systems. Our engineering team selects and configures each pump based on chamber volume, target gas load, required ultimate pressure, and process duty cycle.
We currently offer one core product family within this category, with configuration options to match different PVD system sizes and process requirements.
This pump serves as the primary roughing and backing stage for high-vacuum pumps such as diffusion, turbomolecular, or roots pumps. It rapidly reduces chamber pressure from atmosphere to the 0.1–0.01 Pa range, creating a stable foreline environment for the entire pumping stack.
Our vacuum pumps are selected to match the specific demands of different PVD coating applications. The table below summarizes typical process requirements and how our pump configurations address them.
| Coating Type | Typical Base Pressure | Pump Role | Zenix Configuration Focus |
|---|---|---|---|
| Hard coatings (TiN, TiAlN, CrN, DLC) | 10⁻³ – 10⁻⁴ Pa | Foreline for turbomolecular/diffusion pump | High throughput, low backstreaming |
| Decorative coatings (ZrN, TiCN, Cr) | 10⁻² – 10⁻³ Pa | Roughing and backing | Fast cycle time, oil mist control |
| Functional coatings (EMI, optical) | 10⁻³ – 10⁻⁵ Pa | Foreline for high-vacuum pump | Low vibration, clean operation |
Our vacuum pumps are built with high-strength alloys and advanced heat treatment for core components, achieving an average service life exceeding 20,000 hours under normal industrial conditions. We optimize the oil circuit and sealing design to reduce energy consumption and emissions, lowering long-term operating costs.
Each pump undergoes factory testing before shipment. We verify ultimate pressure, pumping speed, noise level, and leak tightness. Our quality control includes helium leak detection and performance benchmarking against reference standards. Pumps are packaged with protective covers and desiccant to prevent contamination during transit.
Our vacuum pumps are designed for seamless integration with PVD Hard Coating Machine, Decorative PVD Coating Machine, and Functional Coating Machine systems. We provide the necessary inlet/outlet flanges, oil mist filters, and vibration isolation mounts. For existing installations, we can supply replacement pumps with matching interfaces and performance specifications.
We also offer commissioning support, including pump-down curve verification, leak checking, and operator training on maintenance procedures.
To prepare an accurate proposal, we typically require the following project details:
We supply genuine spare parts including oil, filters, seals, and vanes. Our service team can provide preventive maintenance schedules and remote troubleshooting. For global customers, we coordinate with local service partners to ensure timely support.
We currently supply mechanical pump / foreline pump solutions optimized for PVD coating systems. These pumps serve as roughing and backing stages for high-vacuum pumps.
Yes, our pumps can be configured with standard flange interfaces and performance characteristics to replace or supplement pumps in existing vacuum systems. We will need the current pump model and system specifications to confirm compatibility.
Under normal operating conditions with proper maintenance, our pumps have an average service life exceeding 20,000 hours. Actual life depends on process gases, duty cycle, and oil change intervals.
Yes, we offer commissioning support including pump-down curve verification, leak testing, and operator training. Remote assistance is also available.
Each pump ships with an operation manual, maintenance guide, and test report. We can also provide material certificates and compliance documentation upon request.
