Models A & B - Milton Roy · mRoy series Models A & B metering pumps are controlled-volume, ... scale and corrosion inhibitors, ... Plastic Liquid Ends

mRoy series Models A & B metering pumps are controlled-volume, hydraulically-

actuated diaphragm pumps that are 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. This field-proven design enables

metering with repetitive steady-state accuracy at a ±1% range. Designed to

meet global industry standards, Models A & B provide accurate dosing of a broad

spectrum of fluids. Like all mRoy metering pumps, Models A & B are built to run

constantly all year long with preventative maintenance, leading to decades of

consistent performance.

ApplicationsInjection 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:

• Chemical and petrochemical processing• Cooling towers and boilers • Drinking water treatment• Oil and gas production • Food and beverages industry• Industrial water and wastewater treatment• Pharmaceuticals production• Power generation

Features and 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.

• Metallic and non-metallic liquid end materials, available for corrosion resistance in any chemical application.

• The pump is capable of withstanding a wide range of fluid and ambient temperatures with options for extreme low and high temperature requirements.

• Simplex and duplex versions available.

• The pump meets standards for CE, ATEX, and API 675.

• Extensive motor mount and pipe connection options are available for process compatibility and simple integration into chemical injection systems.

• Process compatibility options are easily selected such as heating/cooling liquid end jackets, configurations for slurries or viscous fluids, unique material combinations, etc.
