Product Description:

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).


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. 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.
