Bell & Gossett 1BL034 PL-75 1/6 HP Motor

Medium-head radiator systems use Bell & Gossett 1BL034 PL-75 for closed-loop hydronic circulation and convector heating applications. Its 1/6 HP single-phase motor operates at 115 V, while the cast iron body, alloy steel shaft, and glass-refined PPO impeller support compatible heating loops. Fill and vent the system, verify the pump remains flooded, and confirm the operating curve before startup.

The Series PL PL-75 uses a cast iron body intended for closed loops and a glass-refined PPO impeller for hydronic circulation. Its 115 V electrical configuration supports compatible single-phase circuits, while the alloy steel shaft transfers motor power through the pump assembly. Verified data does not include GPM, maximum head, amp draw, seal material, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so confirm complete system requirements before installation.
