Consistently Accurately Metering Pump

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. They feature a compact, variable eccentric drive that changes the stroke length by repositioning the center of the shaft in the eccentric.

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: 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, control, and more
• 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 over-pressure, cavitation and lack of pulsation dampening that can cause disturbance and inaccuracy in the dosing process
