Product catalog summary

General Specifications
The Milroyal D pumps feature a polar crank design with all moving parts submerged in oil. They are available with either a High Performance Diaphragm (HPD) or a Packed Plunger liquid end. The pumps can be multiplexed, allowing up to six pumps to be driven by one motor. Maximum performance ratings per head range from 53 GPH at 70 PSIG to 0.5 GPH at 3000 PSIG. Capacity control is available via a manual micrometer, with electronic stroke length control or variable speed as optional features. The accuracy is ±1.0% over a 10:1 turndown ratio. The weight with motor is approximately 195 lbs for HPD and 95 lbs for Packed Plunger.

Performance and Limitations
Typical performance is based on a 1725 RPM, 60 Hz motor, with flow rates needing adjustment for other RPM speeds. Plastic liquid ends are limited to 150 PSIG at 68°F and are linearly derated to 65 PSIG at 140°F.

Model Codes and Options
The document provides detailed model codes for both Packed Plunger and HPD models, including options for connections, gear ratios, packing lube, plunger diameter, liquid end material, motor mount, and capacity adjustment. Notable options include NPT and ANSI threaded connections, various gear ratios, and different materials for liquid ends such as 316 SS, Plastic, Alloy 20, and Alloy C22.

Materials of Construction
The materials used in construction vary between the Packed Plunger and HPD models. For Packed Plunger, materials include PVC, Alloy 20, and 316 SS, with options for ceramic balls and PTFE packing. The HPD model uses materials like 316 SS, Alloy 20, and Alloy C22, with elastomer/PTFE diaphragms.

Dimensions
Dimensions for both the Packed Plunger and HPD liquid ends are provided, with specific notes on configurations such as ball check arrangements.
