Modular Designed Metering Pumps
Primeroyal PQ Model

The PRIMEROYAL PQ metering pumps are versatile, reliable pumps that consistently and accurately inject chemicals. The pumps’ field-proven 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 up to 8,657 l/h (2,199 gph). 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.
