Bell & Gossett 179274LF E9026S 1.25AAB Series e90 Pump

Bell & Gossett 179274LF E9026S handles institutional HVAC circulation through a 1-1/4-inch flanged 1.25AAB configuration. The supplied listing describes the unit as a 1/2 HP single-phase pump for medium-flow hydronics, but the official Series e-90 parts reference associates model E9026S with a different horsepower rating. Verify the nameplate, motor data, and seller’s model documentation before purchase to avoid selecting the wrong replacement.

The supplied product information identifies 115 or 208–230 V single-phase power, a stainless-steel shaft sleeve, and a carbon, ceramic, and Buna-N mechanical seal. Those details point to a serviceable institutional HVAC circulator, but flow, head, pressure, amp draw, dimensions, and weight were not provided. Confirm the actual horsepower discrepancy, flange spacing, shaft arrangement, and system curve before installation.

Key Features & Benefits

- 1.25AAB Pump Size: Provides a 1-1/4-inch flanged connection reference for institutional HVAC replacement.
- Horsepower Verification Required: Helps prevent a costly mismatch because the supplied listing and official model reference differ.
- Single-Phase Voltage: The supplied data lists 115 or 208–230 V for compatible service-panel connections.
- Stainless-Steel Shaft Sleeve: Provides a specified sleeve material for shaft protection during circulation.
- Carbon/Ceramic/Buna-N Seal: Helps contain fluid at the shaft in compatible hydronic service.
- Series e-90 Platform: Supports institutional HVAC applications where pump selection must follow the verified nameplate and curve.

Why Choose Bell & Gossett 179274LF E9026S

The E9026S may suit institutional HVAC circulation, but its horsepower information requires verification before purchase. Resolving that discrepancy is the main buying priority, followed by matching the 1.25AAB flange configuration and mechanical details.

- Build: Stainless-steel shaft sleeve, carbon/ceramic/Buna-N seal, and flanged Series e-90 construction are identified in the supplied data.
- Value: Nameplate verification before ordering can prevent installing a motor with the wrong horsepower or electrical requirement.
- Audience: Suited to institutional HVAC contractors, hospital maintenance teams, boiler technicians, and facility engineers.

Applications & Use Cases

Use Bell & Gossett 179274LF E9026S only after confirming the horsepower and model information against the manufacturer’s current documentation. The supplied data identifies a 1-1/4-inch flanged configuration but does not provide dimensions, weight, or port reach, so check flange spacing, valve access, motor clearance, system curve, and nameplate details before ordering.

Warranty & Support

- Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with the seller.
- Request written confirmation of the horsepower, SKU 179274LF, model E9026S, and 1.25AAB configuration before purchase.

Do not energize the replacement until the motor nameplate, phase, voltage, and horsepower have been confirmed. After installation, fill and purge the loop, inspect the seal and flange gaskets, and verify operation against the approved system curve.
