mROY® Metering Pumps

Maximize uptime with unrivaled accuracy and reliability.

Setting the worldwide industry standard for critical process control

mROY series metering pumps control chemical dosing with unmatched accuracy and reliability.  This dosing pump is durable, compact in design and enables metering of some of the harshest chemicals with repetitive steady-state accuracy at a ±1% range.

It’s not unusual to find mROY metering pumps still operating at design performance after 20 or more years of service.  That’s because mROY maximum uptime pumps are comprised of a unique set of technical features that deliver consistent chemical injection performance with minimal maintenance requirements.


mROY® MRA Series

mROY® series model A metering pump is controlled-volume, hydraulically-actuated diaphragm pump that is designed for consistent chemical delivery. Its compact design contains a plunger that reciprocates at a fixed stroke, displacing a fixed volume of hydraulic fluid and thereby actuating a flexible, chemically inert PTFE diaphragm to create the pumping action. Designed to meet global industry standards, model A provides accurate dosing of a broad spectrum of fluids. Like all mROY® metering pumps, model A is built to run continually all year long with preventative maintenance, leading to decades of consistent performance.

Benefits

  • Hydraulically balanced PTFE diaphragm, designed for 96,000 hours operating life, does not use seals and eliminates plunger packing maintenance.
  • Liquid end bleed system makes it easier to commission a new or a newly maintained pump.
  • Worm and pinion drive operating in an oil bath lubrication produces a smooth mechanical motion that eliminates wear and tear of mechanical lost motion designs and assures long gear and bearing life.
  • Dust-tight cast iron housing provides a rugged enclosure for operation in the harshest plant and field environments.
  • Micrometer capacity adjustment enables accurate output flow control.
  • Internal hydraulic pressure relief valve automatically protects the pump’s hydraulic system from over pressure conditions.
  • High-performance, adjustable, cartridge-type check valves provide positive, repeatable sealing on every pump stroke.
  • The pump meets standards for API 675.

Applications

Injection of chemicals such as coagulants, biocides, disinfectants, polymers, softening agents, acids and bases for pH control, scale and corrosion inhibitors, oxygen scavengers, process additives, and many more for the following areas of application:

  • Municipal water & wastewater treatment
  • Industrial water & wastewater treatment
  • Chemical and petrochemical processing
  • Cooling towers and boilers
  • Oil and gas production
  • Pharmaceuticals production
  • Power generation
  • Agriculture

Technical
