Field-Proven Metering Pumps
Primeroyal PN Model

• 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

Packed plunger, PTFE or metallic diaphragm liquid ends available

• Liquid end body in 316L S.S., 17.4 PH, PVC or PVDF. Other materials such as Alloy 20, Hastelloy, super duplex available upon request
• Diaphragms in PTFE, 316L or 301 stainless steel; plunger in ceramic (Al203) or chromium oxide coated
• 6 stroke speeds/gear ratios available with 50 Hzmotor: 64, 78, 96, 117, 149 and 180 spm. 5 stroke speeds/gear ratios with 60 Hz-motor: 77, 94, 115, 140 and 179 spm
• Manual, electrical or pneumatic stroke length adjustment
• Fixed stroke version. A variable speed motor can allow to instantly vary the flow rate
• IEC or NEMA mounting, motor for frequency variation
• Electric equipment for non-hazardous or hazardous area, large variety of protections and insulations
• Conforms to ATEX CE EX II 2G/D c T4/T3 with ATEX motors
• Optimum protection for critical processes or pumped fluids: double or triple diaphragm, diaphragm failure detection, temperature probes
• Special valves for any type of fluid (including concentrated sulphuric acid and slurries)
• Remote head, cooling/heating jacket to operate into processes requiring low/extreme fluid temperatures
• Full set of connections: screwed or flanged connectors(ANSI, DIN or ISO)
• Wide range of accessories available to complete your dosing installation

• 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
