The mROY XW metering pump delivers precise, consistent chemical dosing with a durable, hydraulically-actuated PTFE diaphragm. Engineered for reliability, it operates continuously for decades, meeting global standards while handling a wide range of fluids with accuracy. Compact yet powerful, it's built for long-term industrial performance.

  • Material (liquid end): 316SS
  • Pressure max: 3,000 psi / 137.9 bar (metallic liquid end)
  • Flow max: 9.2 gph / 34.8 lph (metallic liquid end)
  • Flow variation control: Manual / Remote
  • Certifications: API 675

The mRoy series model XW is engineered for durability and precision, featuring a hydraulically balanced PTFE diaphragm with a 96,000-hour operating life, eliminating the need for seals and plunger packing maintenance. Its liquid end bleed system simplifies startup, while the worm and pinion drive, operating in an oil bath, ensures smooth motion and extends gear and bearing life. A rugged, dust-tight cast iron housing enables reliable operation in harsh environments. The micrometer capacity adjustment allows for precise flow control, while the internal hydraulic pressure relief valve safeguards against overpressure. High-performance, adjustable cartridge-type check valves provide consistent, reliable sealing. Designed to meet API 675 standards, this pump delivers superior performance and longevity.
