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 to 10 to 100% of the nominal flow rate, 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 centric this API 675-compliant pump has been designed to deliver maximum performance within a minimized footprint.

 

Main benefits:

  • Compliant with API 675 standards
  • Adaptability and accuracy: capacity adjustable while running or stopped (stroke micrometric adjustment, 10 turns only from 0 to 100%)
  • Space constraints: Available in vertical or horizontal motor configurations
  • Suitable for the majority of fluids and a large number of industrial processes: several stroke speeds for an accurate dosing
  • Modular design to precisely fit your needs: more than five designs of liquid ends, specific check valves, adaptable connection types, control…
  • Multiplexing capability: to reduce pulsations, meet a specific flow rate by reducing the number of parts, the power consumption and the footprint or to inject several products
  • Long life: ensured by a robust and proven construction, oil bath lubrication to ensure reliability during continuous operation, best materials
  • Safety: diaphragm liquid ends guaranteed leak-proof with service life in excess of 20,000 hours
  • Operations even in the most extreme conditions: specific configurations to operate in saline/offshore conditions, desert, low temperature environment
  • Global design: can comply with the main worldwide certifications and systems: ATEX, NACE, SASO, Customs Union, etc.
  • Over-pressure protection: integrated safety valve to protect the pump on diaphragm liquid ends
  • Maintenance easy and fast: the patented MARS system (Mechanically Actuated Refill System) avoids the need to delicately adjust the refill valve.
