Zhejiang Ouhang Electromechanical Co., Ltd. (OH) designs and manufactures high-performance Vacuum Pumps For Laboratory & Industrial Use. We serve global original equipment manufacturers (OEMs) who demand precision, durability, and clean operation. Our dry, oil-free technologies deliver reliable vacuum performance for high-sensitivity environments. With over 12 years of specialized expertise, we ensure our systems meet your complex analytical and industrial needs.
Modern facilities cannot risk oil mist contamination. It compromises sensitive samples and damages precision equipment. Our oil-free solutions provide dry, reliable air path performance without lubricating oils. This clean design keeps your processes uncontaminated. It also ensures compliance with strict laboratory and clinical standards.
At Zhejiang Ouhang, we operate strictly as a dedicated B2B component manufacturer. We do not sell finished consumer goods. Instead, we focus on designing and mass-producing internal compressor and vacuum pump components. If you are an OEM seeking a reliable supplier, we provide the robust foundation your finished products need.
Some market queries ask for fully assembled systems. However, OH does not supply finished retail oxygen concentrator machines. We are a leading component supplier providing the internal compressor engines for these devices. Focusing on specialized component-level R&D allows us to guarantee unparalleled product consistency. This ensures seamless integration for global device manufacturers.
Selecting the right internal components determines your system's efficiency and lifespan. We engineer every pump to meet the highest performance benchmarks. Our in-house engineering team brings over 25 years of technical expertise. These products provide long-term reliability and precise pneumatic control across all standard and custom series.
Industrial processes and analytical labs often require unbroken, continuous operation. We engineer our durable vacuum products to meet these high-demand scenarios. They feature heavy-duty, wear-resistant piston and diaphragm designs. These units support continuous operation for up to 8,000 hours. This exceptional service life minimizes downtime, reduces maintenance costs, and maximizes productivity.
A noisy environment hampers focus and safety in research or clinical facilities. We prioritize low-noise operation using balanced motor designs and advanced acoustic dampening. Our industrial vacuum pumps operate quietly between <42dB and <58dB. This ensures a vibration-free dry vacuum experience. They integrate seamlessly into noise-sensitive laboratory benches and medical treatment rooms.
In highly sensitive analytical chemistry and medical filtration, oil contamination compromises results. It can also damage downstream diagnostics. As a trusted manufacturer, OH designs specialized dry pumps that eliminate lubricating fluids entirely. Our hydrocarbon-free systems ensure that only clean, uncontaminated air passes through. This protects your research samples and equipment longevity.
Our robust production facility spans 8,000 square meters. With an annual output value of 100 million RMB, we are fully equipped for high-volume OEM orders. We manage over 18 independently developed product series. This provides a wide array of choices to fit different system footprints, flow rates, and pressure limits.
| Pump Series | Flow Rate Range | Max Vacuum Level | Noise Level (dB) | Primary OEM Application |
|---|---|---|---|---|
| Dry Piston Series (Standard) | 30 L/min - 120 L/min | -90 kPa to -98 kPa | <48 dB | Laboratory filtration & medical PSA systems |
| Compact Diaphragm Series | 15 L/min - 50 L/min | -85 kPa to -93 kPa | <42 dB | Aesthetic skin therapy & dental suction lines |
| High-Flow Industrial Series | 100 L/min - 250 L/min | -95 kPa to -99 kPa | <58 dB | Heavy-duty laboratory automation & gas handling |
These OEM components utilize advanced dry piston pump technology. They deliver high flow-to-size ratios for easy integration into compact medical and scientific chassis. To explore custom mechanical integration options, please contact our engineering team.
Our clean, durable solutions satisfy the strict performance requirements of modern high-tech industries. By integrating directly into complex equipment, our pumps provide consistent negative pressure. This precision is required for multiple critical applications worldwide.
In testing laboratories, vacuum stability is vital for precision analytics. Our pumps integrate seamlessly with rotary evaporators, filtration manifolds, desiccation cabinets, and chromatography equipment. This secure, hydrocarbon-free dry vacuum prevents sample cross-contamination. It ultimately supports highly accurate analytical device integration.
In medical devices, component reliability is a matter of patient safety. Our quiet and clean pumps are vital components for oxygen concentrators. They provide the steady air management required for molecular sieve pressure swing adsorption. Our high-reliability designs ensure safe, uninterrupted oxygen delivery.
Modern clinical treatment rooms demand compact, ultra-quiet components. Our engineering supports dental equipment applications, handling wet and dry suction lines easily. Additionally, our space-saving pumps integrate widely into premium aesthetic devices. These include microdermabrasion and skin-therapy units where precise pressure controls are critical.
Standard off-the-shelf pumps do not always fit unique medical or industrial chassis. As a specialized custom OEM/ODM pump services provider, we guide global manufacturers through a high-efficiency engineering process. This ensures we deliver perfectly tailored pneumatic components.
1. Technical Selection: Our engineers analyze your specific flow rate, pressure, and envelope dimensions to establish the project baseline.
2. Rapid Prototyping: We build and test customized prototype units to ensure physical and performance compatibility with your chassis.
3. Scaled Production: Utilizing our state-of-the-art 8,000-square-meter factory, we manufacture your custom units under strict quality control.
4. Agile Delivery: Leveraging our global supply chain, we maintain a reliable 7-15 days standard delivery window for product batches.
5. Ongoing Mass Support: We offer dedicated after-sales support and continuous engineering modifications to match your product's market evolution.
