PRIMEROYAL® Series
Metering Pumps

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 seven 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.

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

Primeroyal series pumps are ideal for critical processing industries & applications:

Oil and Gas. Primeroyal pumps can be used in upstream, midstream and downstream sectors as well as produced water treatment.  These pumps can be used for the injection of methanol, corrosion inhibitors, sodium hypochlorite, scale inhibitors, oxygen reducing agents, and many more.

Drag Reducer Agents (DRA). With decades of experience and a field proven design, Milton Roy’s DRA pumps provide precise injection at strategic points along a pipeline network to reduce turbulence and optimize flow efficiency.

Chemical and Petrochemical Processing. Dosing catalysts for polymerization of polyethylene is a prime use for the Primeroyal and Primeroy pumps.

Power Generation. High-pressure boiler feed water treatment is essential to operations and these pumps can assure accurate, efficient dosing of the necessary chemical agents.

Water / Wastewater Treatment:

Municipal (drinking) water treatment – disinfection, fluoridation, coagulation /flocculation, pH control, water conditioning before and / or after RO treatment in desalination plant, and more.

Industrial water treatment – protection of installed equipment such as boiler and hydraulic systems to prevent scale and corrosion.
