Pompes Grosclaude

What Pompes Grosclaude does

Pompes Grosclaude is a French designer and manufacturer of customized centrifugal pumps, founded in 1950 by René Grosclaude and headquartered in Bron near Lyon. The company specializes in small-series and unit-quantity production of centrifugal pumps for complex industrial applications, serving enterprise customers across chemical, pharmaceutical, nuclear, defense, aerospace, agro-food, cosmetics, construction, and automotive industries. Its customer roster includes Arkema, BASF, Sanofi, Merck, Syngenta, Airbus, Naval Group (formerly DCNS), CEA, and CNRS, indicating both French and international penetration. The current SAS corporate entity was registered on December 30, 2008, and was acquired by engineer Sander van Langen (ICPI Lyon, class of 1995) in 2009 with the objective of perpetuating and developing the business.

The product portfolio spans more than 20 pump families, including standardized centrifugal pumps (ALFA, EX-BX), monoblock pumps (MF, MX, MR), magnetic drive sealless pumps (MGX, LGF/LGX, ZS-SEMA), side channel pumps (ZS-S, ZS-SRZS, ZS-SV), vertical long-shaft pumps (R0, R1/R14, ALFA V), extreme-temperature variants operating from -110°C to +350°C, liquid-ring vacuum pumps (ZAV), integrated vacuum skid systems (GV), and nutating disc volumetric pumps (M series). Engineering relies on in-house 2D (AutoCAD) and 3D (Solid Edge) CAD plus proprietary internal simulation tools, with full ATEX 94/9/CE and 2014/34/UE certification from INERIS across five pump families for explosive atmospheres. Notable proprietary technologies include magnetic coupling (eliminating product leakage), vortex impeller design (handling solids up to 1 cm and aerated liquids), and integrated closed-loop vacuum skid architectures.

Revenue is generated through direct, quote-based sales of capital equipment (hardware), supplemented by bespoke engineering, retrofit of obsolete pumps, custom skid assemblies integrating pumps with filtration and instrumentation, and a long-tail spare parts and after-sales service business serving equipment installed as far back as the 1970s. Pricing is per-project with no public list; customers engage via website, phone, or direct outreach. Distribution is direct (no resellers), with active international outreach supported by a multilingual website in French, English, and Spanish. The company is privately held under individual owner-operator management, with no institutional investment or public listing disclosed.
