Hydraulic Pump / Motor Mounts (“Bellhousings”) Bell Housings

The Cast Aluminum Pump / Motor Mounts are made from a lightweight, high strength aluminum alloy.

Hydraulic Pump / Motor Mounts (“Bellhousings”) Bell Housings Additional Resources

Lovejoy Hydraulics Pump / Motor Mounts help power unit designers and fabricators simplify their Power Unit designs. The Pump / Motor Mount, commonly called the “Bell Housing”, allows direct mounting of flange mount pumps to NEMA “C-Face electric motors. This eliminates the need for coupling guards, foot brackets, shims, risers, and motor mounting plates, and assures accurate shaft alignment.

The ease of assembly reduces power unit fabrication costs. Lovejoy precision machines each cast aluminum alloy pump/motor mounts to 0.003 inch concentric from the motor pilot to the pump pilot, and the mounting faces parallel to each other and perpendicular to the pilot Centerline within 0.002 inch. This assures accurate shaft alignment, which prolongs bearing, seal and coupling life. This also helps to reduce noise and vibration in the power unit.

Lovejoy Hydraulics Cast Aluminum Pump / Motor Mounts are cast from a lightweight, high strength aluminum alloy. For safety, a molded OSHA orange coupling access cover is included for mounts larger than the 56C motor frame size.

For more unique requests, please contact Lovejoy customer service.

Should you have a problem finding a Lovejoy Hydraulics distributor in your area, please contact a Lovejoy sales representative or ask your current Lovejoy Power Transmission distributor to start carrying and supporting the new products!
