Taco 1634E 1600 Series Cast Iron Centrifugal Pump 1HP 1PH

Run commercial boiler and chiller loops with Taco 1634E 1 HP single-phase centrifugal pump. Its 115 or 230-volt motor provides up to 150 GPM and 50 feet of head, while the 13.4A or 6.7A full-load current affects electrical planning. The 2-inch flange suits commercial hydronic piping. Confirm the flange layout, system curve, service voltage, and access before installation.

The 1634E uses a cast-iron pump assembly with a 1 HP single-phase motor configured for 115V or 230V, 60 Hz service. Its published maximum flow is 150 GPM and maximum head is 50 feet, with a 52-foot shut-off head reference. Full-load current is listed as 13.4A or 6.7A. The supplied specifications do not state RPM, impeller material, seal construction, dimensions, weight, pressure, or temperature.

Applications & Use Cases

Apply this pump to commercial boiler and chiller loops within the listed 150 GPM and 50-foot limits. Check the 2-inch flange, gasket fit, pipe supports, valve clearance, motor access, and electrical current before installation. Overall dimensions, weight, pressure, temperature, impeller material, and seal details are not supplied, so verify them first.

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.
• Model Verification: Match Taco 1634E, 1 HP, single-phase configuration, and SKU 1634E-1 to the seller’s order documentation.

Verify 115 or 230-volt service, align the 2-inch flange, purge air, inspect strainers, and check for leaks during startup. Select the running point from the actual pump curve rather than shut-off head.
