What Transfluid does

Transfluid S.p.A. is an Italian industrial engineering company founded in 1957, headquartered in Gallarate (VA), Italy, that designs and manufactures power transmission components and systems for industrial and marine applications. The portfolio is centered on hydrodynamic power transmission technology and includes constant and variable fill fluid couplings (K, KX, KFBD, SKF, KSL, KPTB, KPTO, and high-speed series), clutches and power take-offs (HFO-HFR, MFO, SH-SHC, TPO-TPH, PF, SU, TowerClutch), flexible and elastic couplings (BM-B3M-BMS, RBD), modular pump drives (Stelladrive MPD and SPD, SRBD), industrial powershift transmissions (Rangermatic, Revermatic, Drop Box), and an expanding hybrid and electric propulsion line (HTM700 marine hybrid, HTV700 industrial hybrid, HM hybrid module, EM permanent magnet synchronous electric machines, Tier G electric power train, LiFePO4 batteries, and Bellmarine electric propulsion). The company's proprietary Transfluid Circuit design and patented KX Series circuit deliver soft-start, variable-speed, torque-limiting, and torsional-vibration-dampening performance for machinery driven by electric motors and internal combustion engines, with the proprietary MPCB controller providing SAE J1939 CAN BUS-based monitoring and control.

The company operates a sales-led, hardware-based business model. Products are manufactured and sold globally via five wholly-owned subsidiaries (Italy HQ, USA, China, France, Netherlands), complemented by a network of more than 30 authorized dealers across North America and Europe and an ecommerce storefront at buy-transfluid.com offering 5-day shipment on standard parts. Pricing is quote-based rather than list-published. Transfluid serves seven primary verticals — Medium-Heavy Industry, Marine & Shipbuilding, Raw Materials & Mining, Building & Construction, Transport & Automotive, Oil & Gas, and Energy & Water — with use cases spanning centrifugal pumps, compressors, fans, blowers, mills, marine propulsion, dredges, winches, mining machinery, construction equipment, special vehicles, drilling rigs, and wind/power-generation equipment. Through the 2018 merger with Bellmarine, which formed Transfluid North Europe B.V., the company added an electric and hybrid marine propulsion capability with over 4,000 systems installed. The company is privately held (Italian Società per Azioni) with registered capital of EUR 520,000, has no public funding rounds on record, and reports no publicly disclosed revenue figure.
