Frequently Asked Questions
Common questions from PSU procurement officers and plant maintenance buyers sourcing Balmerol Protomac SP gear oil through Vasundhara.
What is Balmerol Protomac SP gear oil and who manufactures it?
Balmerol is the lubricants brand of Balmer Lawrie & Co. Ltd, a Schedule-A Mini Ratna Govt of India PSU operating under the Ministry of Petroleum & Natural Gas. Protomac SP is the industrial gear oil sub-range covering ISO VG 100 to 680 EP grades. Manufacturing is done at Balmer Lawrie's BIS / ISO 9001 / ISO 14001 / ISO 45001 certified plants. The brand has 100+ years of presence in India (Balmer Lawrie was founded in 1867).
How does Balmerol Protomac SP compare to Veedol Apreslube, IOCL Servomesh SP or Castrol Alpha SP at the same VG?
Not quite all four, and the gaps are the useful part. Balmer Lawrie publish Protomac SP to IS 8406 with DIN 51517 Part 3 (CLP) and ISO 12925-1 CKD. Veedol publish Apreslube to DIN 51517 Part 3, ISO 12925-1 CKC/CKD, AGMA 9005-E02 and AIST 224. Castrol publish Alpha SP to DIN 51517 Part 3 but do not cite ISO 12925-1. IOCL publish Servomesh SP to AGMA 250.04, IS 8406-1993, US Steel 222 and 224 and IPSS 1-09-003, and cite neither DIN 51517 nor ISO 12925-1. If your tender names IS 8406, Protomac SP and Servomesh SP are the two that carry it. Balmerol's structural advantage is PSU-manufactured status — relevant for buyers with Make-in-India / PSU-preference procurement clauses (defence, Indian Railways, state utilities, central PSUs). For private-sector buyers without such preferences, all four are commercially-equivalent; selection comes down to price, availability and existing OEM approval at the specific gearbox model. Vasundhara supplies Veedol AND Balmerol from the same warehouse — common for buyers running both brands across different gearboxes.
Can I procure Balmerol gear oil through GeM for PSU procurement?
Yes. Balmerol Protomac SP industrial gear oils, SAE 80W-90 and 85W-140 automotive gear oils, and open-gear compound are all available to PSU buyers on GeM for PSU buyers — Indian Railways, BHEL, NTPC, NLC India, Coal India, ONGC, SAIL, RINL, Defence establishments, state cement corporations, state transport corporations. Vasundhara is a GeM-registered seller. GFR-2017 compliant for deferred-payment supply with documentation pack including Udyam-MSME registration, manufacturer authorisation from Balmer Lawrie, and standard PSU procurement compliance suite.
Is Balmerol Protomac SP suitable for Indian Railways workshop gearboxes?
Yes. Balmer Lawrie has been a long-standing Indian Railways supplier across multiple lubricant categories. Balmerol Protomac SP VG 100/150/220 grades are commonly issued to Railway workshops for traction-motor reduction-gear cases, locomotive auxiliary gearboxes, and rolling-stock final-drive axles. Specifications align with IRS / RDSO specs for industrial gear oils where applicable. Per-batch test certificates and BIS conformance reports support Railway audit requirements.
What is the typical drain interval for Balmerol Protomac SP VG 220 EP in industrial service?
For well-maintained industrial gearboxes with proper filtration (10-micron return-line filters) and bulk-oil temperature staying below 80°C, Balmerol Protomac SP VG 220 EP typically delivers 6,000-12,000 hours of service life. With synthetic PAO grades the interval extends to 15,000-25,000 hours. Drain-interval optimisation via periodic oil-sample analysis (TAN/TBN, viscosity, water content, particle count, wear-metal spectrometry) typically extends intervals 20-40% over manufacturer-default schedules.
Can Balmerol Protomac SP be mixed with Veedol, Servo or Castrol gear oil during top-up?
Yes — mineral-base Balmerol Protomac SP grades are compatible with most other mineral-base gear oils from major Indian and international brands at the same viscosity grade. Top-up volumes <20% of system capacity rarely cause issues. Synthetic PAO grades are also miscible with mineral oils but with some performance reduction. Best practice: maintain single-brand single-grade policy per gearbox to avoid unintended additive interactions and to simplify oil-sample analysis interpretation. Document any cross-brand top-up event in the equipment's lubrication log.
Does Balmerol Protomac SP meet IS 8406 / IS 1118 specifications?
Yes. Balmerol Protomac SP industrial gear oils meet IS 8406:1993 (Specification for industrial gear oils) and IS 1118:1992 (Specification for industrial mineral oils) where applicable to the grade. BIS-marked grades available for buyers requiring formal BIS certification on the supply. Per-batch BIS conformance reports provided as part of the standard documentation pack.
Is Vasundhara the authorised Balmerol Protomac SP distributor for Hyderabad?
Yes. Vasundhara Performance Solutions Pvt Ltd is the authorised Balmer Lawrie / Balmerol industrial lubricant distributor for Hyderabad, Telangana and Andhra Pradesh. We supply genuine Balmerol products manufactured by Balmer Lawrie & Co. Ltd, with full manufacturer authorisation documentation provided on enquiry.
