HI-FAB Engineers

What HI-FAB Engineers does

HI-FAB Engineers Pvt. Ltd. is a privately held Indian manufacturer of mechanical seals, seal support systems and lip seals, headquartered in Mumbai with a state-of-the-art production facility in Daman and dedicated service centers in Bharuch and Hyderabad. Founded in 1982, the company is one of the first Indian firms to indigenously design, develop and market mechanical seals, and operates with a 250+ employee base supplying 50M+ units cumulatively across eight primary verticals: oil & gas, petrochemicals, power, pharmaceuticals, fertilizer, pulp & paper, mining and OEM pump/agitator manufacturers. Its core technology centers on mechanical seals engineered to API 682 and EN12756 standards — including cartridge seals, component seals, agitator seals, dual and metal bellow designs — alongside the proprietary HIFLON modified PTFE material used in its HLS range of high-performance lip seals for abrasive and aggressive media applications.

The company's product surface spans the full sealing stack: mechanical seals (universal cartridge, heavy-duty dual, metal bellow, PTFE bellow, single/multispring pusher, elastomeric bellow, agitator and glasslined reactor seals), the complete API 682 seal portfolio (Arrangements 1, 2, 3, 2/3 plus the full Plans 11/21/22/23/32/52/53/54/65/72/74/75/76 flushing plan family), seal support systems (thermosyphon, forced lubrication, pressure balancing) and bare and cartridge lip seals. Revenue is generated through direct enterprise field sales on a quote-based model (no public pricing), supplemented by a Product-as-a-Service (PaaS) module offering customizable Annual Rate, Maintenance and Service contracts. Go-to-market is purely direct, with PAN India service engineers providing installation, commissioning, inspection, retrofitting, audit, training and emergency support, and the company claims presence in international markets without disclosing specific overseas offices or subsidiaries.
