Product catalog summary

Overview
Lovejoy Hydraulics specializes in manufacturing flexible drive couplings, particularly Pump/Motor Mounts or 'Bell Housing', which allow direct mounting of flange mount pumps to NEMA C-Face electric motors. This design reduces the need for additional components, ensuring accurate shaft alignment, minimizing noise and vibration, and extending the life of bearings, seals, and couplings.

Specifications
Lovejoy offers mounts in SAE and Metric pump flanges, and NEMA and IEC motor mounts, made from high-strength aluminum alloy. Safety features include an OSHA orange coupling access cover. Horizontal mounts have a weep hole for leakage detection, while vertical mounts provide a compact assembly.

Selection Data
The document includes detailed dimensional data for SAE and Metric pump mounts, with 2-bolt and 4-bolt configurations, and ANSI shaft codes for various shaft types.

Procedures
The selection process involves identifying pump mounting type and motor frame size, calculating minimum face-to-face length, and selecting the appropriate mount. Clearance checks between mount surfaces and coupling dimensions are recommended.

Recommendations
For custom mounting needs, Lovejoy offers consultation services. Following bolt torque recommendations from the BHN Pump/Motor Mount Bolt Torque Table is emphasized for secure installations.

Product Warranty
Lovejoy provides a warranty against defects in material and workmanship, covering repair or replacement of defective products, with transportation costs borne by the purchaser. The warranty excludes liability for special, incidental, or consequential damages and personal injury.

Pump and Motor Mount Specifications

Horizontal Mounts: For frame sizes 182TC to 256TC and 284TC to 405TSC, with dimensions from 6.81 to 8.75 inches.
Vertical Mounts: For frame sizes 56C, 143TC/145TC, and 182TC to 256TC, with dimensions from 3.50 to 7.00 inches.

Mounting Types and Dimensions
