The API 675 compliant PRIMEROYAL pump is designed for the consistent and accurate delivery of flow assurance chemicals used to enhance offshore product recovery, eliminate corrosion, and prevent the formation of hydrates or wax deposits. The PRIMEROYAL® range provides accurate dosing of a broad spectrum of fluids at flow rates that can reach maximum 13,068 gallons per hour (49,470 liters per hour) in the triplex configuration. With its versatile, modular design and a wide range of options, PRIMEROYAL® pumps can be configured precisely for your applications. PRIMEROYAL® pumps are built on a modular technology platform that adapts to a wide range of applications. They feature multiple liquid ends and capacity-control options for the specific requirements of your application. More than a half-century of experience combines with advanced pump-engineering technologies to give you continuous operation with the longest possible time between scheduled maintenance.

The workhorse of the portfolio is the mROY® metering pump. This pump has been upgraded and offers enhanced safety, improved hydraulic efficiency, easier startup and maintenance, and the same accuracy and reliable performance that Milton Roy is known for. Produced in a variety of models and frame sizes that provide capacities from 0.20 gallons per hour up to 87 gallons per hour in a simplex configuration, the mROY metering pump boasts a hydraulically balanced diaphragm with 96,000-hour design life and a three-year warranty.
