What are some common applications where long-coupled pumps with spacer couplings are typically used?

Long-coupled pumps with spacer couplings are commonly used in applications where ease of maintenance and reduced downtime are critical, such as in commercial HVAC systems, industrial processes, and large-scale water treatment facilities. They are also often used in applications where space is limited, such as in rooftop HVAC units or in tight mechanical rooms. Additionally, spacer couplings may be specified in applications where high reliability and uptime are essential, such as in hospitals, data centers, or other critical facilities.
