Commercial high-head circulation can use the Bell & Gossett e-1510 1.5BC with a 3 HP, 1,750 RPM three-phase ODP motor, 208 to 230 or 460 V supply, stainless steel shaft sleeve, and Wood’s Sure-Flex coupling. Its listed maximum capacity is 190 GPM at 58 feet, subject to curve-based selection.

The base-mounted arrangement requires foundation, coupling alignment, rotation, and service-clearance planning. Because the listed 190 GPM and 58-foot figures represent maximum references rather than guaranteed simultaneous duty, final approval should compare the actual system curve, required head, NPSH, pressure, and selected impeller configuration.

Technical Specifications

- The 3 HP motor establishes the listed power class for electrical planning and replacement comparison.
- Operating at 1,750 RPM, the four-pole speed affects curve selection and rotating-equipment coordination.
- 208 to 230 or 460 V three-phase power requires compatible motor connections and protection.
- The ODP enclosure requires environmental conditions appropriate for open drip-proof motor construction.
- A stainless steel shaft sleeve provides the documented shaft-protection material for service review.
- Wood’s Sure-Flex or equivalent coupling requires alignment and guard-clearance planning.
- Maximum performance is listed as 190 GPM and 58 feet, requiring duty-point verification.

Hydraulic Performance and Application

The listed maximum performance is 190 GPM at 58 feet, while the application record identifies commercial HVAC supply service. These figures do not define a normal operating point, and no exact efficiency or NPSH value is supplied. Final selection requires the applicable pump curve and system resistance.

Installation Requirements

Confirm three-phase voltage, ODP environmental conditions, foundation, 2.5-inch suction and 1.5-inch discharge piping, rotation, shaft-sleeve fitment, coupling alignment, guard clearance, and service access before startup. The selected operating point must remain within the approved pressure, temperature, and performance limits.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from shipment or a 1-Year Limited Warranty from installation, whichever occurs first, covering defects in materials and workmanship. Improper installation, misuse, alteration, negligence, and contrary operation are excluded. Shaft-sleeve and coupling condition remain relevant service checks. Mulmotor provides product-information support before purchase and order assistance.
