MTH 56 C-face Adapter

Fits a P31, T31, or C Series Pump to any Standard 56 C-face Motor

There are now two options when it is necessary to use special configuration motors or special enclosure motors for the P31, T31, and C Series pumps. Previously, it was necessary to mount the pump on a bearing frame and connect to the motor using a flexible coupling. Now, using the 56 C-face adapter to build a close coupled pump for these applications allows a smaller footprint and better alignment.

Application Uses

Use the 56 C-face Adapter with any 56 C-face motor including:

  • Explosion Proof

  • Open Drip Proof

  • Totally Enclosed Fan Cooled

  • Switched Reluctance

  • Variable Speed Motors

  • 56 C-face AC motors

  • 56 C-face DC motors

“This rugged adapter has a built in bearing for stronger, better alignment of the shaft, resulting in longer seal life and improved wear.”
