DVO 120 High Vacuum Oil

Operating high-speed, single-stage rotary vane vacuum systems demands an optimization fluid that balances rapid internal heat transfer with absolute structural stability. Dinesh High Vacuum Engineering’s DVO 120 is custom-compounded to meet this exact challenge. Engineered as a premium functional equivalent to Leybold LEYBONOL LVO 120, this specialized lubricant brings highly refined mineral bases and targeted performance enhancements into your production line. Unlike standard baseline oils, DVO 120 falls into the precise ISO VG 32 classification. This specific viscosity profile is selected by engineers to ensure rapid fluid circulation during crucial system startup phases while maintaining a resilient sealing film under continuous operating temperatures. 🛡️Key Features & Technical Benefits -- Overcoming Startup Electrical Overload : Thicker vacuum oils can create heavy viscous drag when a pump is activated cold, leading to tripped breakers and excessive motor wear. -- Active Oxidation Resistance : When exposed to compressed atmospheric gases and frictional heat, raw mineral oils quickly break down into dark, sticky varnishes. -- Accelerated Moisture Separation : Industrial processes frequently pull ambient humidity into the vacuum chamber. DVO 120 features advanced demulsifying properties that prevent water from permanently blending into the oil. ✅Equipment Application Guide : DVO 120 can be introduced directly into machinery requiring an additivated ISO VG 32 vacuum lubricant. It is a direct functional fit for: -- SOGEVAC Single-Stage Lines : Optimized for compact and mid-sized configurations, including the SV 10 B, SV 16, SV 25 B, and SV 65 pump variations. -- High-Speed Rotary Assemblies : Equipment designs requiring an anti-wear fortified mineral oil to protect internal components during constant start-stop cycles. -- Legacy Fleet Operations : An exact chemical drop-in choice for systems originally specified to run on older, discontinued Leybold HE200 fluid grades.

DVO 100 High Vacuum Oil

Dinesh High Vacuum Engineering’s DVO 100 is a premium-grade, highly refined mineral vacuum pump oil formulated without additives. Engineered specifically to serve as a direct, seamless replacement for Leybold LEYBONOL LVO 100, DVO 100 ensures your high-vacuum machinery maintains optimal ultimate pressure, minimal backstreaming, and reliable component protection without the OEM price premium. Whether you are operating high-capacity rotary vane pumps, roots blowers, or industrial diffusion setups, DVO 100 matches the exact physical, thermal, and chemical profile required to protect your internal components from premature wear and thermal breakdown. 🛡️Key Features & Technical Benefits : 1. Ultra-Low Vapor Pressure & Minimal Foaming DVO 100 undergoes strict distillation processing to eliminate low-boiling fraction volatiles. This achieves a remarkably low vapor pressure at high thermal thresholds, preventing vapor migration back into your clean vacuum chamber while maintaining the absolute lowest ultimate pressure capabilities of your pump series. 2. Additive-Free Formula for Chemically Inert Applications Designed completely free of aggressive chemical additives, DVO 100 will not react or break down prematurely when exposed to standard atmospheric air, water vapor, and chemically inert process gases (such as Nitrogen, Argon, and Helium). 3. Rapid Water Separation & Demulsibility Industrial vacuum applications regularly ingest moisture. DVO 100 features high demulsibility properties, meaning it separates water rapidly from the oil layer. This allows condensation to settle at the bottom of the oil reservoir for easy draining, rather than forming a milky emulsion that destroys lubricating efficiency. ✅Direct Pump Compatibility Guide : DVO 100 is engineered to be poured directly into systems utilizing LVO 100 without needing a complex chemical flush. It is fully compatible with the following equipment lines: -- Leybold TRIVAC Series : Compatible with TRIVAC A, TRIVAC B, and TRIVAC E rotary vane pumps. -- Leybold RUVAC Series : Roots vacuum pumps requiring un-additivated ISO VG 100 lubrication. -- Leybold E + DK Series : Rotary piston pump systems running under constant industrial loads. -- Standard Rotary Vane & Piston Pumps : Any industrial high-vacuum pump specifying a non-detergent, additive-free ISO VG 100 vacuum oil. 👌Applications of DVO 100 Vacuum Pump Oil : -- Rotary vane vacuum pumps, High vacuum systems -- Vacuum coating machines, PVD and thin film deposition systems, Vacuum metallurgy -- Vacuum drying chambers, Laboratory vacuum systems -- Research and development facilities, Pharmaceutical vacuum systems -- Freeze drying and lyophilization systems, Transformer oil filtration plants
