Bell & Gossett E9034T Series e90 Inline Centrifugal Pump 2AAB

Distribute high-volume secondary-loop water with Taco 1632E 3/4 HP three-phase in-line centrifugal pump for commercial HVAC systems. Its motor operates at 208–230/460 volts and 1,725 RPM, while the 2-inch flange supports common commercial hydronic piping. Published capacity reaches 145 GPM and 44 feet of head, with a 46-foot shut-off head reference. Confirm electrical protection, system curve, and flange alignment before startup.

The 1600 Series 1632E uses a three-phase, 1,725 RPM motor in an in-line centrifugal pump assembly with a 2-inch flange. Its listed full-load current is 2.8A or 1.4A at the stated voltage points. Maximum flow is 145 GPM and maximum head is 44 feet, while the 46-foot shut-off head describes the zero-flow reference. The supplied data does not state impeller material, seal construction, dimensions, weight, or operating temperature.

Key Features & Benefits

- 3/4 HP Three-Phase Motor: Supports commercial HVAC secondary loops with verified 208–230/460-volt service.
- 145 GPM Maximum Flow: Provides a stated upper reference for secondary-loop circulation selection.
- 44 Feet Maximum Head: Helps contractors compare piping resistance and elevation against pump performance.
- 2-Inch Flange: Supports replacement planning when the existing connection dimensions and bolt pattern match.
- 1,725 RPM Operation: Gives technicians a defined speed reference for commissioning and equipment comparison.
- 2.8A/1.4A Full-Load Current: Assists electrical review at the listed voltage points.
- 46-Foot Shut-Off Head: Identifies the listed zero-flow value and should not replace curve selection.

Why Choose Taco 1632E

The Taco 1632E provides published flow, head, speed, amperage, and connection data in a 3/4 HP three-phase package. It fits commercial secondary loops where the system requires a 2-inch flanged pump and available electrical service matches the motor.

- Build: The 1600 Series in-line arrangement and 2-inch flange define the supplied replacement interface.
- Value: Published hydraulic and electrical information helps reduce selection errors before a scheduled shutdown.
- Audience: Suits commercial HVAC contractors, facility engineers, boiler technicians, and plant maintenance teams.

Applications & Use Cases

Use this pump in commercial HVAC secondary loops within the listed 145 GPM and 44-foot maximums. Check the 2-inch flange dimensions, gasket condition, pipe supports, valve clearance, motor access, and phase rotation before installation. The supplied specifications do not include overall dimensions, weight, impeller material, seal details, or temperature limits, so verify those items in the manufacturer’s documentation.

Warranty & Support

- Warranty Terms: Warranty duration, coverage, exclusions, and registration requirements require confirmation from the authorized seller.
- Service Requirements: Confirm whether authorized service is required for warranty claims before purchase.
- Model Verification: Match Taco 1632E, 3/4 HP, three-phase configuration, and SKU 1632E-3 to the seller’s order documentation.

Verify voltage, phase rotation, and required motor protection before wiring. Align the 2-inch flange, purge air, inspect strainers, and check for leaks during commissioning. Use the actual system curve rather than the shut-off value to confirm selection.
