High-demand hydronics use Bell & Gossett 168036 Series 1535-358S for primary HVAC circulation and commercial heating loops. Its 1-1/2 HP single-phase motor accepts 115 or 208 to 230 V, while the NEMA 56J frame, renewable stainless steel sleeve, and 175 PSI working pressure support demanding service. Confirm the carbon, ceramic, and Buna-N seal, system curve, and connection arrangement before startup.

The Series 1535-358S uses a NEMA 56J motor frame with stainless steel shaft protection and multi-material sealing. Its single-phase electrical configuration supports compatible commercial systems, while verified data does not include GPM, maximum head, amp draw, RPM, impeller material, connection size, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the primary HVAC duty point before installation.
