LDI INDUSTRIES

About LDI INDUSTRIES

LDI Industries is a manufacturer of hydraulic system components, primarily known for pump motor adapters and return flanges for hydraulic tanks. The company's product line focuses on standardized interfaces that connect electric motors or gas engines to hydraulic pumps, as well as flanges that facilitate fluid return lines in hydraulic reservoirs. These components are used in industrial hydraulic power units, mobile equipment, and stationary machinery where reliable fluid power transmission is required. LDI Industries' pump motor adapters are available in multiple configurations, including SAE A and SAE B bolt patterns, with two-bolt or four-bolt mounting options, and accommodate motor frame sizes ranging from 56C-145TC to 182TC-256TC. The adapters are constructed from cast aluminum, offering a balance of strength and weight reduction, and are designed for horizontal or vertical mounting orientations. The return flanges are made from steel and come in pipe sizes such as 3/4 inch and 1 1/4 inch, with corresponding cut-out sizes for tank installation. These flanges are intended for welding or bolting onto hydraulic tank walls to provide a secure return port. 3G Electric supplies a range of LDI Industries components, including multiple SKUs of pump motor adapters and return flanges, supporting maintenance and replacement needs for hydraulic systems. The inventory covers common adapter patterns and flange sizes, allowing engineers and procurement specialists to source standardized parts without custom fabrication. Each component is identified by manufacturer part numbers such as 5111, 5113, 6028, 6019, 1952, 1950, 6029, and 1960, ensuring traceability and compatibility with existing systems. The adapters are designed to meet industry-standard mounting dimensions, facilitating integration with NEMA motor frames and SAE pump flanges. The return flanges are built to withstand typical hydraulic system pressures and are suitable for use with various hydraulic fluids. By offering these components, 3G Electric enables maintenance teams to restore hydraulic system integrity quickly, reducing downtime in applications such as material handling, construction equipment, and industrial automation.
