About this detail

An inline volume pump with variable frequency drive is suspended from the structure using a minimum of four all-thread rods equipped with vibration isolators and a channel frame bolted to the pump base. Single sphere flexible connections are installed on both sides of the pump, complemented by weld neck flanges, pump flange taps, and a minimum twenty-four-inch spool piece or five pipe diameters where possible. The assembly incorporates lug style butterfly isolation valves with gear operators, a flanged silent non-slamming check valve, and a wye strainer with a blowdown valve. Instrument piping includes a half-inch ball valve, a half-inch pressure-temperature port, and a liquid-filled pressure gauge with a needle isolation valve located at a maximum of five feet above the finished floor. The supply and return lines feature additional manual balancing valves, motorized control valves, spring-loaded check valves, and isolation ball valves.
