Bell & Gossett Series 1531 Model 5BC Pump 7-1/2 HP 1750 RPM Motor

Massive HVAC flow demands Bell & Gossett Series 1531 Model 5BC for large-volume circulation, flood-control systems, and commercial building water movement. This 7.5 HP close-coupled pump operates at 1750 RPM with 6-inch suction and 5-inch discharge connections, while the internal self-flushing seal and stainless steel shaft sleeve support large hydraulic service. Confirm the pump curve, motor phase, suction conditions, and piping support before startup.

The Bell & Gossett e-1531 5BC uses a close-coupled configuration with a 7.5 HP four-pole motor and large flanged connections. Its internal self-flushing mechanical seal supports seal-area cleanliness, while the stainless steel sleeve protects the shaft interface. Verified data does not include voltage, amp draw, GPM, maximum head, impeller material, operating temperature, dimensions, weight, thermal protection, or pressure-switch settings, so final selection must follow the approved hydraulic curve.
