Variable Excentric Drive Metering Pump
Primeroyal PR Model

The PRIMEROYAL 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 with a +/-1% steady state accuracy, over a range from 10 to 100% of the nominal flow rate. They feature a compact, variable eccentric drive that changes the stroke length by repositioning the center of the shaft in the eccentric.


Model PR provides accurate dosing of a broad spectrum of fluids used in many industrial processes due to its modular design which offers several types of liquid ends, capacity control options and other configuration options enabling it to meet the specific requirements of your process application.
