Bell & Gossett 168025 Series 1535 – 353S – 3/4HP Pump

Description

Secondary hydronic loops use Bell & Gossett 168025 Series 1535-353S for pressure boosting, cooling systems, and commercial circulation. Its 3/4 HP single-phase motor accepts 115 or 208 to 230 V, while the close-coupled centrifugal design, NEMA 56J frame, and balanced enclosed impeller support compact installation. Confirm the 225°F temperature limit, system curve, flange arrangement, and suction conditions before startup.

The Series 1535-353S uses a close-coupled configuration with an enclosed balanced impeller and NEMA 56J motor frame. Its single-phase electrical setup supports compatible heating and cooling systems, while verified data does not include GPM, maximum head, amp draw, RPM, seal material, connection size, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the secondary-loop operating point before installation.
