High-Pressure Metering Pump
Primeroyal X (PX) Series

PRIMEROYAL® metering pumps are versatile, reliable pumps that consistently and accurately inject chemicals. The pumps’ fieldproven 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, and repeatability. They feature a compact, variable eccentric drive that changes the stroke length by changing the position of the center of the shaft in the centric this API675-compliant pump has been designed to deliver maximum performance within a minimized footprint.

Model X provides accurate dosing of a broad spectrum of fluids at pressures up to 1,029 bar (14,924 psi) and a maximum flow rate of up to 16,490 l/h (4,198 GPH) per dosing head. Available in vertical or horizontal motor configurations and with ability to accommodate three types of liquid ends, PRIMEROYAL X can meet the specific performance requirements of numerous industrial applications.

Benefits

Compliant with API675 standards

Adaptability and accuracy: capacity adjustable while running or stopped (stroke micrometric adjustment, 10 turns only 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 an accurate dosing
Modular design to precisely fit your needs: more than five designs of liquid ends, specific check valves, adaptable connection types, control…
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, best materials
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, low temperature environment
Global design: can comply with the main worldwide certifications and systems: ATEX, NACE, SASO, Customs Union, etc.
Over-pressure protection: integrated safety valve to protect the pump on diaphragm liquid ends
Maintenance easy and fast: the patented MARS system (Mechanically Actuated Refill System) avoid the need to delicately adjust the refill valve
