Armstrong Packaged Coupling Insert for Series Pumps

The Armstrong Packaged Coupling Insert (also called a pump coupler insert or flexible coupling insert) is a genuine Armstrong replacement part for the flexible coupling on Armstrong series pumps. It sits between the coupling halves and joins the motor shaft to the pump shaft. This lets the pump transmit power while absorbing some shock and misalignment.

Key Features:

• Genuine Armstrong pump part made for Armstrong pump couplings
• Woods-style flexible insert design
• Flexible element between the coupling halves that cushions shaft torque transmission
• Packaged by Armstrong as a ready-to-install replacement
• Available in several insert sizes to match different pump coupling configurations

Replacing a worn or damaged coupling insert helps keep the pump running smoothly and reduces vibration. It also helps protect the pump and motor shafts and bearings from extra wear. Check that the insert size matches your pump's coupling before ordering.
