Critical-Process Applications Reach Higher Pressures

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

•    Compliant with API 675 standards
•    Adaptability and accuracy: capacity adjustable while running and stopped (stroke micrometric adjustment, ten (10) turns only from 0 to 100%, graduation scale in %)
•    Space constraints: minimized footprint and weight, available in vertical or horizontal motor configurations
•    Suitable for most fluids used in industrial processes: many stroke speeds for accurate dosing
•    Modular design to precisely fit your needs: multiple options for liquid ends, check valves, connection types, and control
•    Multiplexing capability: provides cost savings in power consumption and asset footprint while reducing pulsation and required NPSH, capable of injection several different products at multiple specific flow rates
•    Long life: high-quality materials engineered to a robust and proven construction, oil bath lubrication to ensure reliability during continuous operation
•    Safety: leak-resistant diaphragm liquid ends with service life over 20,000 hours. Operates in the most extreme conditions: specific
•    Operates in the most extreme conditions: specific configurations to operate in saline/offshore conditions, desert, or low temperature environment
•    Global design: complies with major global certifications and systems: ATEX, NACE, SASO, Customs Union, etc.
•    Overpressure protection: integrated safety valve to protect the pump on diaphragm liquid ends
•    Efficient maintenance: the patented Mechanically Actuated Refill System (MARS) eliminates the need for adjustments the refill valve
