PRIMEROYAL®

Primeroyal series pumps combine robust, field-proven technology, flexible design, and chemical delivery accuracy, making these metering pumps suitable for a large number of industrial processes.

The pumps feature a variable eccentric drive that enables precise control of the pump delivery rate while meeting or exceeding industry standards for steady-state accuracy and repeatability. It has an efficient design that achieves reliable performance within a minimal footprint.

Our latest innovation to the series is the Primeroyal X metering pump. It has been designed to provide accuracy in the even most challenging environments up to 20,000 psi (1,372 bar).

The Primeroyal are available in five frame sizes with a wide range of flow rates and pressures to precisely configure the pump for your application.
  • Flow rate: from 0.05 gph (0.2 l/h) to 4,136 gph (15.66 m3/h) in simplex configuration
  • Pressure: up to 20,000 psi (1,379 bar)
  • Multiplexable
  • Accuracy: ┬▒1%, even for low flow rates and high pressures
  • Stroke adjustment: from 0 to 100% of nominal flow rate
  • Explosion-proof version: conforming to ATEX CE EX II 2 G/D c T3 or T4 upon request
Built to API 675 standards, these pumps provide maximum performance in a minimal footprint.

Compact, variable eccentric drive. They feature a variable eccentric drive with a no-lost-motion design.  This drive enables precise control of the pump delivery rate while meeting or exceeding industry standards for steady-state accuracy and repeatability.

Modular design. Milton Roy Primeroyal pumps are an integrated pump system that can be precisely configured for your application.  There are five frame sizes with a wide flow rate and pressure range, a selection of packed plunger, PTFE and metallic diaphragm liquid end types, and the capability for multiplexing in any combination of frame sizes.
