Milton Roy introduces the new Primeroyal™ Q-Series

July 9, 2024

A major advance in chemical dosing technology

Milton Roy, a leading manufacturer of metering and mixing equipment, is proud to announce the launch of the new Primeroyal™ Q-Series (PQ) chemical metering pump. This state-of-the-art addition to the already comprehensive Primeroyal™ range promises to set a new performance benchmark for a wide range of industrial applications. The PQ Series features an extensive and modular API 675 range with eight different drive sizes and nine advanced fluid end technologies, ensuring unparalleled versatility and meeting the most demanding hydraulic performance requirements for high flows and high discharge pressures.

The Primeroyal™ Q-Series pushes the boundaries of metering pump technology, offering a maximum flow rate of 8,657 l/h (2,199 gph) per metering head and a maximum discharge pressure of 1,035 bar (15,011 psi). This remarkable addition to the Primeroyal™ range meets a wide range of customer requirements, providing a robust and adaptable solution that delivers outstanding performance in the toughest industrial conditions. Designed to withstand the rigors of continuous 24/7 operation, the Q-Series is the epitome of reliability and endurance, meeting the demands of 24/7 operation without compromising on performance or precision.

Unmatched versatility

The Primeroyal™ Q-Series is designed with three proven fluid end types – piston, PTFE or metal diaphragm – which have been the cornerstone of reliability in the Primeroyal™ and Milroyal® series for over two decades. The dual diaphragm fluid end technology, combined with a sophisticated leak detection system, offers the highest level of safety when handling all types of fluids, including critical, toxic, harmful and explosive process fluids.

Key features of the Q Series include:

Compliance with API 675 standards for continuous accuracy (±1%), linearity and repeatability (±3%)

High performance:

o Max. flow rate: 8,657 l/h (2,199 gph) per dosing head
Max. discharge pressure: 1,035 bar (15,011 psi)
o Max. suction pressure: 371 bar (5,380 psi) especially for use with liquid gases

Competence for contract documentation

As a value-added service and an essential part of your contract, the documentation produced by our Contract Documentation Department guarantees compliance with the standards in force. This department is at your disposal, allows continuous conformity control and brings together all the documents related to the purchase, such as certificates of conformity, protocols, drawings and data sheets prepared by the design office, which allow flexibility in carrying out possible revisions to the project drawings and documents.

Cross-industry applications

The Primeroyal^™ Q-Pumps are specifically designed to meet a wide range of fluid dosing requirements, with a focus on industries such as:

Oil and Gas: For high-pressure methanol injection at the wellhead and injection of corrosion inhibitors and chemicals for processing refined products

Chemical and petrochemical processing: For precise dosing of catalysts in polymerization processes

Power generation: For high-pressure boiler feed water treatment and more

Milton Roy’s Primeroyal™ Q-Series sets new standards in metering pump performance. Its modular design offers numerous configuration options to meet the specific requirements of different industrial applications.
