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

Engineered for process-critical applications, the PRIMEROYAL Flat Twin (PX FT) metering pump is Milton Roy’s most powerful pump explicitly designed for high performance industries and applications. The modular design is smaller and lighter than comparable Primeroyal models while maintaining a respectable performance with flows reaching up to 32,295 l/h (8,351 gph) and pressures up to 1,029 bar (15,000 psi).

Benefit:

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
