Modular Designed Metering Pump

The PRIMEROYAL® PQ (replacing PP) metering pumps are versatile, reliable pumps that consistently and accurately inject chemicals. The pumps’ fieldproven design enables precise control of the pump delivery rate while meeting or exceeding industry standards for steady state accuracy and repeatability. They feature a compact, variable eccentric drive that changes the stroke length by changing the position of the center of the shaft in the eccentric. Model PQ provides accurate dosing of a broad spectrum of fluids at flow rates that can reach more than 8657 l/h. The pump has a modular design that accepts three types of liquid ends and offers capacity control options so it can meet the specific requirements of a large number of demanding industrial processes.
