Since 1936, Milton Roy pumps have been valued by customers for their durability and dependability in critical chemical dosing applications. PRiMeRoyal continues that tradition with a variety of frames and configurations that fit the needs of the most demanding processes.

The PRiMeRoyal series foundation is based on a robust gear mechanism and a modular design that accepts several styles of liquid ends and capacity control options. This means every pump is tuned to the specific needs of its application. The use of solid engineering principles assures that even the smallest detail of the design is focused on providing continuous operation with the longest possible time between scheduled maintenance. The final product is a trustworthy metering pump that is an integral part of your process.

General Specifications

PRIMEROYAL® Capacity and Pressure Ratings

The PRiMeRoyal® variable eccentric drive enables precise control of the pump delivery rate while meeting or exceeding industry standards for steady state accuracy and repeatability. The design provides this high level of performance within a small space, so PRiMeRoyal® can fit into tight spaces.

The variable eccentric mechanism changes the stroke length by changing the position of the center of the shaft in the eccentric. To understand this better, assume the setting is at 0%. At 0%, the shaft is dead center of the eccentric and does not transfer any motion to the plunger. By increasing the capacity setting, the center point of the shaft moves from the center point of the mechanism and stroke length gradually increases until the setting is at 100%.

The PRiMeRoyal® variable eccentric is a non lost motion design as compared to designs that have stop plates or rods to limit the plunger travel. These lost motion units also rely on spring return mechanisms to keep the plunger in contact with the eccentric. The PRiMeRoyal® powers the full stroke cycle thus avoiding the mechanical and hydraulic shocks inherent in lost motion drives.

in critical processes, the variable eccentric drive assures both durability and optimum performance for the entire chemical dosing system.

PRIMEROYAL® Standard Liquid Ends

Milton Roy’s HPD liquid end has proven its value to customers for decades. it combines the bestcharacteristics of traditional liquid ends into a simple but elegant design.

• Hydraulically balanced diaphragm minimizes stress and assures long diaphragm life.

• Diaphragm PTFE wetted surface provides wide application coverage while composite materials allow maximum flexibility

• Patented diaphragm design is reusable after pump disassembly

• 3 psia net positive inlet pressure required

• Adjustable internal relief valve in hydraulic system protects pump from overpressure

• Patented MARS hydraulic fluid compensation system eliminates the need for process side diaphragm containment that restricts flow

• Diaphragm design life of 49,000 hours continuous duty

• Handles pressures up to 3,500 psi (240 Bar) without impact on diaphragm life

• Optional materials handle temperatures up to 300° F

Packed Plunger

The packed plunger liquid end offers the best performance when net positive inlet pressure (NPIP) is an issue.

The plunger is in direct contact with the process fluid creating the most efficient pumping performance.

• Excellent for viscous fluids and slurries

• 1 psia net positive inlet pressure required

• Options available to handle temperatures as high as 600° F

• Pressures up to 20,000 psi (1380 Bar)

• Standard ceramic plungers provide long plunger life
