The GRACO 15H880 is a motor coupler kit designed to install electric motors on E-Flo® 4-Ball Piston Pumps. It is a mechanical component that connects the motor shaft to the pump’s gear reducer, ensuring proper alignment and torque transmission. The kit includes a coupler and a key, and is intended for use with NEMA 182/184 TC Frame motors rated at 3 or 5 HP. Material is not explicitly specified, but typical couplers are made from hardened steel or similar durable alloys.

Applications:
Used to install electric motors on GRACO E-Flo® 4-Ball Piston Pumps in industrial and maintenance applications, such as fluid circulation and transfer in various industries.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, alignment, and reliability, reducing the risk of equipment failure and downtime.
• Thoroughly clean the input shaft and motor shaft before installation
• Do not reuse old keys or setscrews; use only the parts supplied with the coupler
• Assemble the key in the input shaft keyway and the setscrews in the coupler, ensuring they do not encroach on the keyway or shaft bore
• Slide the coupler onto the shaft until it bottoms out on the tapered step
• Tighten setscrews to 66-78 in-lb (7.4-8.8 N•m)
• Apply antiseize lubricant to the bore of the coupling
