Milton Roy manufactures controlled volume (metering) pumps and injection equipment specifically designed for aggressive environments, extreme pressures, and variable flow ranges in a wide range of applications and markets. Since 1936, Milton Roy has concentrated its scientific, engineering and production resources on the development and manufacture of equipment that accurately controls fluids in the most demanding environments.
Delivering Milton Roy’s World-Class Dosing Solutions to Your Facility.
Milton Roy is recognized globally as the premier manufacturer of controlled-volume (metering) pumps, setting the industry benchmark for accuracy and reliability in critical chemical injection applications. Their technical superiority is rooted in decades of focused engineering designed to handle the most demanding process conditions.
The primary technical advantage of Milton Roy pumps lies in their exceptional precision and repeatability, often exceeding +/- 1% steady-state accuracy across a wide turndown ratio. Their portfolio is heavily focused on compliance with stringent standards, most notably API 675 specifications for positive displacement pumps, ensuring suitability for critical oil & gas and chemical processing environments.
Furthermore, their robust liquid-end designs—particularly their high-performance hydraulically actuated diaphragms—enable the safe handling of aggressive, corrosive, or toxic chemicals at extremely high pressures while minimizing maintenance. Their modular design philosophy also allows for highly customized multiplex configurations to meet specific flow requirements. Choosing Milton Roy guarantees process integrity and long-term operational uptime.
Precision Engineering for Critical Industrial Processes
Integrating Milton Roy’s API 675 compliant metering pumps and chemical injection equipment is a cornerstone of our Measurement & Metering Systems. These specialized, positive displacement pumps enable us to handle aggressive, high-pressure fluids with exceptional precision. Because these assets are critical to process integrity, our Procurement & Supply Chain Management team ensures seamless sourcing and integration, while our Operations & Maintenance (O&M) division leverages their robust design to significantly reduce downtime and lifecycle costs.
Reliable Performance in the Field
The true value of Milton Roy’s hydraulically actuated diaphragm pumps is proven in demanding industrial environments. For example, during complex facility upgrades like our Acid Plant Renovation, the ability to safely and accurately dose highly corrosive chemicals is paramount. By deploying these world-class dosing solutions, we ensure that our specialized industrial and EPC projects meet the highest safety standards and deliver sustained operational reliability.
