Process-Critical Metering Pump
Primeroyal Flat Twin (PX FT) Series

• Utmost performances: High flow rates (up to 32,295 L/h - 8,531 GPH) and High discharge pressure (up to 1,029 bar / 15,000 psi)
• Compliant with API675 standards
• Adaptability and accuracy: capacity adjustable while running or stopped (stroke micrometric adjustment, 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 accurate dosing
• Modular design to precisely fit your needs: three designs of liquid ends, specific check valves, adaptable connection types, rupture detection systems…
• 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, using the best material
• Safety: double 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, PED, SASO, Customs Union, etc.
• Over-pressure protection: integrated safety valve to protect the pump on diaphragm liquid ends
