Polyalphaolefin (PAO) synthetic hydraulic fluid per ISO 11158 HM. ISO VG 32, 46, 68. For high-temperature service (continuous >90°C bulk-oil temperature). Excellent oxidation stability (10,000-15,000 hour drain interval), low pour point (-45°C), maintained additive performance over extended service. Premium for energy-efficient continuous-duty industrial hydraulic systems.
Polyalkylene glycol (PAG) synthetic hydraulic fluid per ISO 12922 HFD-U classification. ISO VG 32, 46, 68. Fire-resistant chemistry — passes spray-impingement ignition test. For safety-critical applications near molten metal: die-casting machines, steel mill hydraulic systems near hot zones, foundry hydraulic equipment. NOT compatible with mineral hydraulic fluid — full flush required during changeover.
Water-glycol fire-resistant hydraulic fluid per ISO 12922 HFC classification. Water content typically 35-50%. For fire-safety-critical applications where HFD-U synthetic ester isn't preferred — coal-mining hydraulic equipment, certain steel-mill hot-zone hydraulics. Lower bulk-oil temperature limit (max 60°C) than HFD-U; reduced pump life vs mineral hydraulic fluid.
Biodegradable synthetic ester hydraulic fluid per ISO 15380 HEES classification. ISO VG 32, 46, 68. Readily biodegradable (>60% in 28 days per OECD 301), for environmentally-sensitive applications — outdoor mobile equipment near water bodies, marine deck hydraulics, agricultural sprayer hydraulics, eco-tourism vehicle hydraulics. Premium pricing — typical for environmental-spec compliance.
NSF H1-registered hydraulic fluid for food-and-beverage process plant hydraulic systems where incidental food contact is part of the operating profile. POE (polyolester) base. ISO VG 32, 46, 68. For food packaging machinery, beverage filling line hydraulics, dairy plant hydraulic systems, meat-processing plant hydraulics.
Specialty synthetic hydraulic fluid for aviation / aerospace ground-support equipment hydraulics, military aircraft auxiliary hydraulic systems, and aerospace tooling hydraulics where mil-spec compliance matters. Phosphate ester or polyolester chemistries. Specialised supply per customer specification.

Where SELCO Synthlube synthetic hydraulic fluids ship from our Hyderabad warehouse — by specialty application profile.
PAG HFD-U or HFC water-glycol fire-resistant hydraulic fluid for hydraulic systems near molten steel — strip mill stand position controls in hot-zone areas, ladle-turret hydraulics, slab caster mould oscillation, blooming mill operating-side hydraulics. Customers across SAIL, RINL, JSW Steel, Visakhapatnam Steel.
PAG HFD-U fire-resistant hydraulic fluid for aluminium / zinc / magnesium die-casting machine hydraulics + sand foundry mould-handling hydraulics. Safety-critical fire-resistance chemistry — mandatory under most factory insurance + safety regulations for die-casting hydraulic systems.
NSF H1 food-grade synthetic hydraulic fluid for food-and-beverage + pharma process plant hydraulics where incidental food/product contact is part of the operating profile. Pairs with our pharma cleanroom portfolio. Genome Valley, Bachupally, Jeedimetla pharma cluster + Tirupati / Vizag food-processing hubs are common customers.
Biodegradable synthetic ester hydraulic fluid for outdoor mobile equipment near water bodies — agricultural sprayer hydraulics, marine deck hydraulics, water-sports / eco-tourism vehicle hydraulics, forestry equipment hydraulics. Environmental-spec compliance for buyers required to use biodegradable fluids.
PAO synthetic VG 46 for continuous-duty 24/7 industrial hydraulic systems where extended drain interval (10,000-15,000 hours vs 4,000-8,000 for mineral) reduces fluid-management cost. Auto-press shops, paper mill press-section hydraulics, pulp/paper digester hydraulics.
PAO synthetic VG 46/68 for industrial hydraulic systems where bulk-oil temperatures consistently exceed 90°C — applications where mineral hydraulic fluid undergoes accelerated oxidation degradation. Glass-plant hydraulics, hot-press hydraulic systems, hot-zone process plant hydraulics.
For applications where mineral hydraulic fluid can't deliver — choosing the right synthetic chemistry (PAO vs PAG vs HFC vs ester) shapes pump life, fire safety, environmental compliance and total operating cost.

Common questions from steel mill, die-casting, pharma and environmental-spec buyers sourcing SELCO Synthlube synthetic hydraulic fluids through Vasundhara.
Five typical drivers for synthetic: (1) High-temperature service — bulk-oil temp consistently >90°C requires PAO / PAG to avoid accelerated oxidation; (2) Fire-resistance requirement — safety-critical applications near molten metal or open-flame zones require HFD-U or HFC fire-resistant fluid; (3) Food-grade incidental contact — NSF H1 registration required for food-and-beverage / pharma applications; (4) Biodegradability — environmental-spec compliance for outdoor equipment near water bodies; (5) Extended drain interval economics — 10,000+ hour drain on PAO synthetic vs 4,000-8,000 on mineral.
HFC water-glycol: water-based (35-50% water content), inherently non-flammable due to water content, lower bulk-oil temperature limit (max 60°C), shorter pump life vs mineral, cost-economic. HFD-U synthetic ester: synthetic ester base (no water), fire-resistant due to spray-impingement ignition behaviour, higher temperature capability (up to 90°C bulk), better pump life than HFC. HFD-U is the preferred fire-resistant choice for new die-casting + steel mill hot-zone installations; HFC remains common in legacy installations.
NO. PAG (polyalkylene glycol) is NOT compatible with mineral hydraulic fluid, PAO synthetic, or polyolester synthetic. Mixing causes seal swelling, varnish formation, possible pump damage. When transitioning to PAG, full flush + change-over is required per the manufacturer's procedure: drain old oil, run flush oil per manufacturer's recommended duration, drain flush, install new PAG. Typically takes 1-2 working days per system. We support changeover planning when Vasundhara is the supply partner.
Yes. SELCO Synthlube food-grade hydraulic fluid is NSF H1 registered for incidental food contact applications — suitable for food-and-beverage + pharma process plant hydraulic systems where occasional contact between hydraulic fluid and food/product is part of the operating profile (typically ≤10 mg/kg incidental contact). NSF H1 registration documentation provided on enquiry.
Well-maintained industrial hydraulic systems with proper filtration and bulk-oil temperature staying below 70°C: SELCO Synthlube PAO synthetic VG 46 typically delivers 10,000-15,000 hours of drain interval (vs 4,000-8,000 hours on mineral hydraulic). Sample analysis (TAN, viscosity, water, ISO 4406 particle count, wear-metal spectrometry) typically extends intervals 30-50% over manufacturer-default schedules. The 3-5× drain extension justifies the 2-3× cost premium for continuous-duty applications.
Yes. SELCO Synthlube Bio Ester hydraulic fluid meets ISO 15380 HEES classification for biodegradable hydraulic fluids — >60% biodegradability in 28 days per OECD 301B test, low aquatic toxicity, no heavy-metal additives. Suitable for environmentally-sensitive applications: outdoor mobile equipment near water bodies, marine deck hydraulics, agricultural sprayer hydraulics, forestry equipment, eco-tourism vehicle hydraulics.
