High-performance heavy-duty formulations engineered for extreme mechanical workloads and severe environment operability.
Modern vacuum pump systems operate under demanding environments: intense mechanical friction, high thermal stress, exposure to corrosive chemical byproducts, and absolute pressure requirements reaching down to $10^{-6}$ mbar. Because of this, traditional standard mineral-based oils struggle to maintain proper viscosity indexes and prevent premature molecular breakdown.
The global tribology field is rapidly moving toward synthetic formulations: polyalphaolefins (PAO), polyol esters (POE), and fluorinated ethers (PFPE). These synthetic bases provide low vapor pressures, high resistance to thermal oxidation, and long operational intervals.
High-vacuum operations require lubricants with a low vapor pressure curve. When selecting wholesale vacuum compressor oils, looking only at ISO VG grades (such as VG 68 or VG 100) is not enough. You must also evaluate the flash point and distillation range. Longhai’s synthetic molecular distillation processes help isolate light ends, ensuring consistent vacuum performance and reduced pump wear.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. Over the last 15 years, we have built a complete industrial chain dedicated to delivering lubrication solutions for the global industrial and transportation fields.
Longhai Technology operates our proprietary brand "Century Longhai" along with the strategically partnered British "A Ba" series. Our wide-ranging catalog covers diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, fully synthetic oil, automotive urea solutions, antifreeze, special motorcycle oils, industrial oils, and automatic transmission oils. Our brands are insured by the PICC (People's Insurance Company of China) for peace of mind.
By following strict international standards, we use advanced blending and fully automatic filling lines with high-precision metering systems. This maintains filling accuracy within 1‰ to 2‰ while increasing overall speeds by 20% to 35% to support fast order delivery.
We support global procurement officers with consistent bulk shipments, complete regulatory compliance, and customized formulas.
Under continuous operation, mechanical shear forces break down the polymer chains in industrial lubricants. This leads to a loss of viscosity and thin oil films. Longhai's vacuum compressor oils are formulated with high shear stability (SSI) base fluids, keeping film thickness consistent even under heavy mechanical loads.
Lubricant formulas must be compatible with seal elastomers (such as Viton, NBR, and EPDM). Using incompatible fluids can cause seal swelling, shrinking, or cracking, which leads to vacuum leaks. We verify elastomer compatibility across our entire product line to keep your systems sealed and secure.
High operating temperatures in air and vacuum systems accelerate oil oxidation, creating acidic products, sludge, and varnish. Our advanced antioxidant additives neutralize these compounds, preventing deposits on vital valves and rotors and lowering overall maintenance costs.
Shandong Longhai Technology provides comprehensive OEM and ODM support for partners globally. Whether you need semi-synthetic or fully synthetic formulations to meet API or ACEA standards, our research teams can tailor lubricants to your specific equipment demands, climatic conditions, and market requirements.
We formulate lubricants to match target performance levels, climatic conditions, or custom API/ACEA specifications.
From small pilot runs to full large-scale manufacturing, we support a wide range of batch sizes and packaging types.
Our operations are certified under ISO 9001, 14001, and 18001, backed by comprehensive laboratory analysis and reports.
We assist with packaging design, custom labeling, and regulatory documentation to help establish your brand image.
At Longhai Technology, quality is the foundation of our business. We have passed ISO 9001:2015 quality system certification, ISO 14001 environmental management certification, and ISO 18001 health management system certification. We also hold official Mercedes-Benz approvals for automotive fluids, which demonstrates our ability to formulate lubricants that meet the strict standards of major global OEMs.
Our quality control labs monitor every stage of production, from checking raw base stocks to testing completed oil batches. We verify key properties like kinematic viscosity, flash point, pour point, water separation, and foaming tendencies to ensure consistent, reliable performance under tough operating conditions.
Our engineering teams focus on developing sustainable, high-performance lubricant solutions for evolving global markets.
We are researching biodegradable synthetic lubricants to help reduce environmental impact without sacrificing wear protection or mechanical performance.
We continue to refine our chemical distillation processes to develop specialized vacuum oils that minimize vacuum chamber contamination.
We are studying the interaction between synthetic lubricants and smart sensor systems to help operators monitor fluid life and schedule preventive maintenance.
