The PQ series boasts an extensive and modular API 675 range that includes eight distinct drive sizes and nine advanced liquid end technologies, ensuring unparalleled versatility, and the ability to meet the most demanding hydraulic performance requirements for high flows and high discharge pressures.
The Primeroyal Q series extends the boundaries of metering pump technology, offering a maximum flow rate of 8,657 l/h (2,199 gph) per dosing head and maximum discharge pressure of 1,035 bar (15,011 psi). This remarkable expansion of the Primeroyal range caters to a diverse spectrum of customer needs, delivering a robust and adaptable solution designed to excel under the most stringent industrial conditions. Tailored to withstand the rigors of continuous, round-the-clock operation, the Q series is the epitome of reliability and endurance, meeting the demands of 24/7 duties without compromise on performance or precision.
Unmatched Versatility
The Primeroyal Q series has been meticulously engineered with three proven liquid end types – packed plunger, PTFE, or metallic diaphragm – that have been the cornerstone of reliability for over two decades within the Primeroyal and Milroyal series. The double diaphragm liquid end technology, coupled with a sophisticated leak detection system, offers superior safety for handling all types of fluids including critical, toxic, harmful, and explosive process fluids.
