Explore our main product portfolio engineered to endure extreme temperature shifts and aggressive mechanical stresses.
Insights into how extreme applications are reshaping chemical formulations, requiring tighter precision and eco-responsibility.
Traditional mineral base oils are giving way to Polyalphaolefins (PAO), Polyol Esters (POE), and Polyalkylene Glycols (PAG). These synthetic variations offer lower volatility, superior viscosity indexes, and lower vapor pressure, which prevent fluid loss and reduce process contamination in high-vacuum systems.
Modern screw and rotary compressors are engineered to run hotter and run continuously. Lubrication solutions must exhibit extreme thermal and oxidative stability to prevent varnish and carbon deposits from forming on hot discharge valves and cooling systems, effectively extending service life up to 8,000+ operational hours.
In industries like semiconductor lithography, thin-film deposition, and food processing, outgassing can ruin multi-million dollar cleanrooms. Next-generation vacuum oils focus on fractional distillation to eliminate lighter hydrocarbon components, keeping vapor pressure in the range of 10-6 to 10-8 Torr under heavy loads.
How global buyers mitigate procurement risks, ensure equipment safety, and optimize operating expenditures.
Industrial distributors and OEM procurement departments are demanding higher transparency. Sourcing vacuum pump fluids and compressor lubricants is no longer just about price. It revolves around strict parameters: consistent viscosity classification (ISO VG 32, 46, 68, 100), density, water-separating properties (ASTM D1401), and compatibility with elastomers like FKM, Buna-N, and EPDM.
Furthermore, supply chain volatility has pushed organizations to focus on manufacturers with massive raw material storage capacity, chemical processing flexibility, and reliable international strategic connections. Companies rely on partner operations with comprehensive quality insurance (such as PICC China People's Insurance Company coverage) to reduce liabilities across international distribution routes.
A premier high-tech enterprise integrating R&D, production, and worldwide sales of advanced lubricants since 2009.
Headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years developing custom lubrication formulations for the global industrial, transportation, and agricultural markets.
We own our flagship brand "Century Longhai" and represent strategic partnerships with the British "A Ba" series of products. Our portfolio spans diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engineering machinery oil, natural gas engine oil, full synthetic oils, automotive urea solution, antifreeze, and specialty motorcycle lubricants.
To secure our customers' trust worldwide, our complete product lineup is insured under quality insurance by PICC (China People's Insurance Company). By integrating foreign production processes and high-tech testing technologies, we ensure optimal equipment efficiency, low vapor pressures, and extended run-times even under extreme industrial working environments.
Combining automated metering systems with deep-sea and cross-border rail connections to guarantee consistent performance.
Our automated blending plant matches critical parameters by using advanced metering technology. By shifting volume adjustments to PLC automation, we keep our volumetric and weight filling accuracy between 1‰ to 2‰. This limits variations in multi-ton export containers.
By standardizing container handling, we have improved our lines' packaging speed by 20% to 35%. This output keeps delivery windows tight, making us a dependable partner for global industrial wholesalers and regional distributors.
Custom formulations designed to maintain vacuum stability and operational reliability in challenging environments.
Our oils work smoothly with various modern refrigerants, maintaining optimal sealing film thickness and chemical stability down to -40°C. They prevent wax precipitation in thermal expansion valves, keeping heat transfer systems running at peak performance.
In high-purity chemical vapor deposition (CVD) and plasma etching, pumps face hot, corrosive process gases. Our synthetic fluorinated (PFPE) and premium hydrocarbon fluids prevent acid formation and maintain target vacuum pressures.
Engineered for large screw compressors handling humid gases. Exceptional water separation qualities prevent emulsification, protecting bearings from premature wear and reducing mechanical downtime.
From tailor-made chemical properties to physical product packaging, we support every phase of your brand's development.
Our laboratory designs fully synthetic and semi-synthetic formulas matching international standards (such as API and ACEA). We customize viscosity parameters, pour points, and additive packages to suit your target regional climates.
