Taco 1632E 1600 Series Cast Iron Centrifugal Pump 3/4HP 3PH

Distribute hydronic water with Taco 1632E 3/4 HP three-phase in-line centrifugal pump for commercial HVAC secondary loops. Its 208–230/460-volt motor runs at 1,725 RPM and delivers up to 145 GPM with 44 feet of maximum head. The 2-inch flange, 46-foot shut-off head, and 2.8A or 1.4A full-load current give technicians practical replacement checkpoints. Confirm the system curve, overload protection, and piping alignment before installation.

The 1600 Series 1632E uses a three-phase motor and a 2-inch flanged centrifugal pump arrangement for commercial secondary-loop service. Its published 145 GPM maximum flow and 44 feet of maximum head provide hydraulic screening references, while the 46-foot shut-off head identifies the zero-flow limit. The listed 208–230/460-volt configuration requires phase and voltage verification. The supplied data does not state impeller material, seal construction, dimensions, weight, or operating temperature.

Key Features & Benefits

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

Why Choose Taco 1632E

The Taco 1632E provides commercial HVAC teams with published flow, head, speed, amperage, and connection data in a 3/4 HP three-phase package. It is suited to secondary loops where the existing system uses a 2-inch flanged pump and available power matches the motor.

• Build: The 1600 Series centrifugal arrangement and 2-inch flange define the supplied replacement interface.
• Value: Published hydraulic and electrical data can reduce selection errors before a scheduled system shutdown.
• Audience: Fits HVAC contractors, facility engineers, boiler technicians, and commercial plant maintenance teams.

Applications & Use Cases

Use this Taco pump in commercial HVAC secondary loops that operate within the listed 145 GPM and 44-foot maximums. Check the 2-inch flange dimensions, pipe supports, gasket condition, 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 and phase rotation, align the 2-inch flange, purge air from the loop, inspect strainers, and check for leaks during commissioning. Select the running point from the actual system curve rather than the shut-off value.
