Hydra-Mount Products
Electric Motor Mount Selection "E" Series

Horizontal hydraulic pump mounts for electric motors, or our “E” series, covers a wide variety of motor to pump options. NEMA-C face motor sizes available range from 56C to the large 404-405 TC. SAE pumps available begin at the 4F17 and range to the D2/4 bolt. Like our other mounts, these are made of lightweight aluminum and are machined to specific tolerances and concentricity to ensure a quality product and reduce wear and stress on your coupling/shaft assembly. Snap-in orange safety access covers are available on all mounts to ensure safety of the assembly while in operation. Most mounts are in stock for immediate delivery.
