Bell & Gossett Series e-1532 2.5BB 5HP 1750 RPM 3PH ODP Pump

Keep multi-story HVAC circulation moving with Bell & Gossett Series e-1532 2.5BB, a 5 HP close-coupled footless pump operating at 1750 RPM. Its 3-inch suction and 2-1/2-inch discharge connections suit main-loop circulation in larger buildings, while the ODP motor and stainless-steel shaft sleeve provide defined equipment details for replacement matching. Confirm the electrical data, case layout, and impeller trim before installation.

The four-pole motor drives a nominal 9.5-inch impeller through the 2.5BB case arrangement. The footless design requires proper pipe support and alignment because the piping layout carries the pump assembly. Voltage, amp draw, flow, head, pressure, dimensions, weight, and seal material were not supplied, so verify the full submittal and foundation-free mounting requirements before startup.
