Field-Proven Metering Pumps

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 PN 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, and other configuration options to meet the specific requirements of your process application.

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%, graduation scale in %)
• Space constraints: available in vertical or horizontal motor configurations
• Suitable for the majority of fluids in all 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: providing cost savings in the power consumption and asset footprint while reducing pulsation and required NPSH and, giving the capability to inject several different products or meet a specific flow rate
• Long life: ensured by using high quality materials engineered to a robust and proven construction, oil bath lubrication to ensure reliability during continuous operation
• 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, or low temperature environment
• Global design: can comply with the main worldwide certifications and systems: ATEX, NACE, SASO, Customs Union, etc.
• Overpressure protection: integrated safety valve to protect the pump on diaphragm liquid ends
• Maintenance easy and fast: the patented Mechanically Actuated Refill System (MARS) on PTFE diaphragm liquid ends avoids the need to delicately adjust the refill valve.

Applications

• Chemical/Petrochemical: chemical injection of additives, transfer of ammonia water in fertilizer plant
• Oil and Gas: chemical injection of methanol, MEG and glycol to protect pipes and avoid any stops of production due to hydrates; injection of wax inhibitors, demulsifiers, pour point depressants to control the oil viscosity; treatment of produced water (transfer, injection of coagulants)
• Power Generation: metering of biocide, hyprochlorite to prevent fouling of the mechanical equipment of the mechanical equipment and pipework
• Refinery/Downstream: chemical injection of dimethyl disulfide (DMD) to activate hydrocraking/hydrodesuphuring catalysts, boiler feed water pump, metering of additives
• Water/Wastewater Treatment:
• Municipal (drinking) Water Treatment: disinfection, fluoridation, coagulation/flocculation, pH control, water conditioning before and/or after RO treatment in desalination, and more
• Industrial Water Treatment: protection of installed equipment such as boilers and hydraulic systems to prevent scale and corrosion
