Low Flow and High Pressure
Primeroyal PK and PKG Models
Primeroyal PK and PKG Models
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.
Models PK and PKG provide 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.
Compartir
- Compliant with API675 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: Minimized footprint and weight, available in vertical or horizontal motor configurations, GSD design for tiny spaces
- 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
- Additional benefits with PTFE diaphragm liquid ends:
- Maintenance easy and fast: the patented Mechanically Actuated Refill System (MARS) avoids the need to delicately adjust the refill valve
- Triple hydraulic security with the GSD design: in addition to the internal pressure safety valve, the diaphragm controls the hydraulic refill and the diaphragm itself is protected by a valve blocking the overrunning and the extrusion
- Installation Monitoring Indicator (IMI) system with the GSD design: visual indication of overpressure, cavitation and lack of pulsation dampening that can cause disturbance and inaccuracy in the dosing process
- Packed plunger, PTFE or metallic diaphragm liquid ends available
- Liquid end body in 316L S.S., 17-4P-H, PVC or PVDF. Other materials such as Alloy 20, Hastelloy, super Duplex available upon request
- Diaphragms in PTFE or 316L stainless steel; plunger in Z55CDV17 steel or chromium oxide coated
- 6 stroke speeds/gear ratios available with 50 Hzmotor: 39, 59, 100, 120, 144 and 180 spm. 5 stroke speeds/ gear ratios with 60 Hz-motor: 47, 71, 120, 144 and 173 spm
- Manual, electrical or pneumatic stroke length adjustment
- 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
- Food grade design (in accordance with CE 1935-2004)
- Special valves for any type of fluid (including concentrated sulphuric acid and slurries)
- Remote head, cooling/heating jacket to operate in 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, injection of co-catalyst such as TEAL for polyethylene and polypropylene, injection of sulphuric acid into water to produce diluted sulphuric acid
- Food and Beverage: injection of enzymes in starch production, injection of caustic soda for process water neutralization in refining and distilling applications
- Oil and Gas: chemical injection of biocide, corrosion / scale inhibitors, hydrogen sulfide (H2 S) scavengers to protect piping and other assets and maintaining production rates, transfer of steam condensate
- Refinery / Downstream: chemical injection for separation and treatment of refined products, injection of paraffin inhibitor into fuel storage tanks
- Water / Wastewater Treatment:
- Municipal (drinking) Water Treatment: disinfection, fluoridation, coagulation / flocculation, pH control, water conditioning before and / or after RO treatment in desalination plant
- Industrial Water Treatment: protection of installation such as boilers and hydraulic systems to prevent scale and corrosion
