The use of a spacer coupling in a long-coupled pump can have a significant impact on the overall cost of ownership by reducing maintenance costs and downtime. With a spacer coupling, maintenance can be performed more quickly and easily, reducing labor costs and minimizing the need for costly repairs. Additionally, the reduced risk of motor misalignment and subsequent vibration issues can help extend the lifespan of the pump and motor, further reducing long-term costs. While the initial cost of a spacer coupling may be higher than a basic coupling, the long-term benefits and cost savings can make it a more cost-effective option.
