Milton Roy Mixing: A Legacy of Technological Pioneers
At Milton Roy Mixing, innovation and expertise form the cornerstone of our success.
By inheriting groundbreaking technologies from Robin Industries and SEM, we’ve continued to build on a legacy of excellence, offering advanced solutions for mixing and agitation. Let us take you on a journey through the rich history and technical mastery that has shaped our reputation in the field.
A Heritage of Excellence: Robin Industries
The story begins in 1895, when Établissements Robin was founded to design and manufacture propellers for the French shipbuilding industry. For over six decades, Robin engineers refined their understanding of blade hydrodynamics — how to convert rotational energy into directed fluid thrust with maximum efficiency and minimum parasitic loss.
In the 1960s, Robin Industries made a pivotal strategic decision: to apply its deep expertise in marine propeller physics to the entirely different — yet fundamentally related — challenge of industrial mixing. The fluid dynamics principles are the same; the operating environment is not. Where a ship propeller must push a vessel through open water, an industrial impeller must create controlled circulation patterns within a confined tank, managing flow direction, shear distribution, and energy dissipation simultaneously.
This transition produced Robin's most enduring contribution to mixing technology: the patented HPM® propeller (Hélice Profilée Mince — thin profiled propeller).
The HPM represented a fundamental rethinking of impeller design for industrial agitation:
- Its helical blade profile generates pure axial flow while virtually eliminating parasitic radial components — directing energy exactly where the process needs it, with no wasted motion.
- The triangular longitudinal cross-section provides exceptional bending strength relative to blade thickness, enabling the propeller to withstand the sustained mechanical loads of continuous industrial operation without fatigue or deformation.
- The adaptable pitch geometry allows each HPM impeller to be tuned for specific process conditions — optimizing the balance between pumping capacity and power consumption for each unique application.
Robin Industries became part of Milton Roy in 1998, bringing with it not just a product line, but an entire school of thought about how impellers should be engineered — from first principles of fluid mechanics, validated by decades of field performance across chemical, water treatment, and process industries.
SEM: The Engineering of the SABRE Propeller
SEM brought international acclaim with the development of Sabre Propellers, a groundbreaking technology designed for axial flow mixing.
These thin, high-efficiency blades, deliver unmatched performance:
- Energy Efficiency: Sabre propellers consume significantly less power than conventional designs.
- Versatile Performance: Their hydraulic efficiency remains nearly unaffected by liquid viscosity, making them suitable for a wide range of applications.
- Proven Results: Advanced calculations guarantee the performance of these propellers.
The Sabre propellers have cemented SEM’s reputation as an industry leader, and their integration into Milton Roy Mixing’s offerings continues to set new standards for performance and reliability.
By combining the ingenuity of Robin Industries and SEM, Milton Roy Mixing has cultivated an unparalleled expertise in mixing technologies. Our robust, efficient solutions are tailored to meet the demands of industries worldwide, ensuring performance and reliability for every application.
Two Legacies, One Unmatched Expertise
By combining the ingenuity of Robin Industries and SEM, Milton Roy Mixing has assembled an impeller technology portfolio without equivalent in the industry. The HPM® and SABRE® represent two complementary engineering philosophies — both rooted in rigorous fluid dynamics science, both proven across tens of thousands of installations, both continuously refined through modern CFD analysis and field feedback.
Today, these technologies power every mixer in the Milton Roy portfolio — from the compact HELISEM® series for standard open-tank applications, to the configured HM Series for water treatment and chemical processing, to the heavy-duty ROBIN® agitators engineered for extreme conditions, to the HELIFLOAT® floating mixers for basins and lagoons, and the side-entry mixers protecting crude oil storage tanks across six continents.
With over 100 years of mixing heritage, a 10,000 m² manufacturing facility at Samoreau (south-east of Paris), and a global network backed by Ingersoll Rand (NYSE: IR), Milton Roy Mixing continues to set the standard for what industrial agitation can achieve — in performance, in efficiency, and in long-term reliabilit
