Their main purpose is to provide an easy way to install, remove, or maintain the pump without needing to cut or disassemble the surrounding pipework. Pump unions typically consist of two threaded halves that can be easily tightened or loosened with a wrench, allowing for quick detachment and reconnection of the pump. They are commonly used in heating systems, water pumps, and circulation pumps to simplify maintenance and ensure a secure, leak-proof connection..
