South Gujarat's chemical corridor, from Vapi and Sarigam to Ankleshwar, Panoli, Jhagadia and Dahej, is one of India's densest concentrations of chemical, dye, pharmaceutical and agrochemical plants. These plants run continuously, and their rotating equipment lives in a harsh mix of heat, humidity, corrosive fumes and frequent wash-downs.
Chemical plants need EP gear oils with strong water separation and rust protection for agitator and cooling-tower gearboxes, water-resistant greases for pumps and motors, compressor oils suited to humid air, and sealed, contamination-free handling. In pharma and food-contact areas, NSF H1 lubricants may be required. Always check lubricant compatibility where chemicals can reach it.
| Equipment | Usual lubricant | Watch point |
|---|---|---|
| Centrifugal pumps (bearing housings) | Bearing oil (often VG 46–68) or EP2 grease, as specified | Water ingress from wash-downs, seal leaks |
| Agitator and reactor gearboxes | EP gear oil, VG 220–320; worm-approved oil for worm units | Heat, continuous running, moisture |
| Cooling tower gearboxes | EP gear oil with excellent water separation and rust protection | Constant humidity, condensation |
| Screw and reciprocating compressors | Compressor oil to the maker's grade | Monsoon condensate, high discharge temperature |
| Centrifuges and dryers | As specified by the maker; high-temperature grease near heat | Vibration, heat |
| Blowers, fans and belt-driven pumps | EP2 grease, classical or wedge V-belts | Fumes attack rubber and metal; check belts more often |
| Conveyors and packing lines | General grease and gear oil; H1 where product contact is possible | Hygiene in pharma areas |
Humidity in South Gujarat stays high for much of the year and peaks in the monsoon. Water gets into gearboxes and bearing housings through breathers, seals and wash-downs. Water in oil speeds up rust, oxidation and additive loss.
Acid and chlorine vapours attack exposed metal, paint and rubber. They can also contaminate lubricants through breathers and open containers.
Agitators run 24 hours a day under steady and sometimes shock loads. Use the EP gear oil grade the maker specifies, often VG 220 or 320. Many agitators use worm gearboxes: confirm that the oil is suitable for bronze wheels before choosing a highly active EP oil. Read EP vs non-EP gear oil.
Where a lubricant could contact a pharmaceutical or food product, plants often specify NSF H1 registered lubricants. Keep H1 and non-H1 lubricants clearly separated and labelled, with dedicated grease guns.
In areas with flammable vapours, a lubricant leak on a hot surface is a hazard. Fix leaks promptly, keep drip trays clean and follow the plant's hot-work and housekeeping rules.
Compressors in this region condense a lot of water, especially from June to September. Keep screw compressors running hot enough to avoid water in the oil, drain receivers every shift and watch for milky oil. See our compressor oil guide.
Chemical plants benefit greatly from consolidation: fewer products mean fewer mix-ups in a busy maintenance department. Banesto is a Gujarat-based manufacturer of industrial and speciality lubricants and Beltone V-belts. Send us your equipment list and we will suggest a consolidated list for your plant.
Which oil is used in agitator gearboxes?Usually an EP gear oil of ISO VG 220 or 320, as the gearbox maker specifies. For worm gearboxes, use an oil approved for bronze wheels.
How do I stop water getting into gearbox oil?Fit desiccant breathers, keep seals in good condition, avoid direct wash-down sprays on seals, and drain water from the sump regularly.
Which grease is best for pumps in wet areas?A water-resistant grease such as calcium sulphonate complex, applied in regular small shots.
Do pharma plants need food-grade lubricants?Where incidental product contact is possible, many plants specify NSF H1 lubricants. Follow your plant's quality and GMP requirements.
