Boiler-feed and high-resistance secondary loops can consider the Bell & Gossett Series e-80 1.5 x 1.5 x 9.5B with 5 HP power, 1,750 RPM operation, 1.5-inch in-line connections, and a 9.5-inch nominal impeller.

The vertical in-line arrangement provides a compact piping configuration for suitable equipment layouts. The supplied record identifies higher head capability than the 3 HP model, but exact flow, head, NPSH, pressure, temperature, efficiency, and motor electrical details require the applicable performance documentation.

Key Features

- The 5 HP motor establishes the listed power class for boiler-room planning.
- Operating at 1,750 RPM provides the speed reference for curve selection.
- 1.5-inch suction and discharge connections support in-line piping compatibility review.
- A 9.5-inch nominal impeller identifies the supplied hydraulic configuration.
- Vertical in-line construction affects piping support and service access.
- Higher head capability than the 3 HP model supports variant comparison.
- Boiler-feed and high-resistance secondary loops define the listed applications.

Hydraulic Performance and Application

The pump is listed for boiler-feed service and high-resistance secondary loops, with higher head capability than the related 3 HP model. No exact flow, head, NPSH, pressure, curve, or efficiency value is supplied, so the 5 HP rating cannot establish the operating point.

Installation Requirements

Confirm 1.5-inch in-line piping, 5 HP motor requirements, 1,750 RPM rotation, support, alignment, service clearance, fluid temperature, pressure, and suction conditions before commissioning. The vertical or horizontal arrangement must follow the manufacturer’s approved configuration and maintain access for inspection and component service.

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. Piping support and internal component condition remain relevant service checks. Mulmotor provides product-information support before purchase.
