Modular Metering Pumps for high pressure

Customized performance when it matters most

The MILROYAL® series metering pumps are the most reliable, industrial-duty metering pumps for critical processes in industries such as oil and gas, chemical and petrochemical processing, Drag Reducer Agent (DRA), and industrial water treatment.

The key to MILROYAL®'s success is its modular design that accepts a variety of liquid ends and other options that perfectly tune it to your process requirements. With three different frame sizes, these pumps provide precision chemical dosing over a wide range of capacities and pressures.

Multiplex configurations of the same frame or a mixture of frames create even greater application flexibility.

The picture above shows a MILROYAL D triplex pump for low flow in special execution with diaphragm leak detection.

Configuration flexibility. The pump’s three frame sizes cover a full range of capacities and pressures, and it has the capability to be multiplexed with up to 8 pumps driven by one motor.

Leak-proof performance. A selection of diaphragms including metallic, high-performance, and critical service diaphragms can provide leak-proof performance at pressures up to 1380 bar.

Accurate flow control. Capacity adjustable by manual control, electronic actuator, pneumatic actuator, or variable speed allows flexible control of chemical delivery.

Performance by the numbers

• Maximum capacities range from 125 l/hr up to 7873 l/hr per drive.
• Pressures range from 7 bar in higher capacities up to 1380 bar in lower capacities.
• ± 1% steady state accuracy over 10:1 turndown ratio. Turndown can be greatly increased with options.

Applications

Oil & Gas. Milroyal pumps are ideal for high-pressure offshore applications. They consistently inject methanol, corrosion inhibitors, oxygen binders, and other corrosive substances in the harshest conditions in the most remote locations.

Drag Reducer Agents (DRA). With decades of experience and a field proven design, Milton Roy’s DRA pumps provide precise injection at strategic points along a pipeline network to reduce turbulence and optimize flow efficiency.

Chemical and Petrochemical Processing. The harsh, toxic chemicals required for chemical processes require metering pumps that ensure accuracy in delivery of these critical and difficult fluids.  Milroyal pumps’ modularity allows a selection of liquid ends and configurations to ensure you get the right pump for chemicals being handled.

Industrial Water Treatment. Industrial process water must be treated efficiently and cost-effectively in compliance with quality standards. The reliability of Milroyal pumps deliver accurate chemical delivery and provide long-term cost benefits.
