Armstrong 4300-12x12x17 Split Coupled Vertical In-Line Pump 100 HP Motor

Description

With a 1-1/2-inch flanged standard port, the Taco 0012-SF4-2 is a stainless-steel circulator with a 1/8 HP motor. Published maximum values are 45 GPM and 13 feet of head. The supplied application context is commercial hot-water recirculation, where flange compatibility, actual loop resistance, and required circulation must be checked before selecting the circulator.

Stainless-steel construction identifies the stated body material, while the published hydraulic values are maximum limits rather than a fixed operating point. Final selection should use the applicable Taco performance curve and consider pipe length, fittings, water temperature, pressure conditions, and connected equipment. Confirm that the 1-1/2-inch flanged interface matches the installed recirculation piping before replacement or new installation.

Key Specifications of the Taco 0012-SF4-2 Stainless Steel Circulator

• A 1-1/2-inch flanged standard port provides the listed connection size for matching commercial recirculation-loop piping.
• Stainless-steel construction identifies the specified body material for this flanged Taco circulator pump configuration.
• The 1/8 HP motor establishes the listed drive size for the supplied commercial hot-water recirculation unit.
• Published maximum flow reaches 45 GPM, defining the stated upper circulation limit rather than a fixed operating result.
• Maximum head is listed at 13 feet, requiring comparison against actual recirculation-loop resistance before equipment selection.
• Commercial hot-water recirculation is the stated application context for evaluating this stainless-steel circulator configuration.

Hydraulic Performance and Application

The Taco 0012-SF4-2 is specified for commercial hot-water recirculation with 45 GPM maximum flow and 13 feet maximum head. These figures define the published performance boundary, not a guaranteed condition for every loop. Select using the applicable Taco curve and project system resistance. Pipe length, fittings, water temperature, pressure conditions, and the connected 1-1/2-inch flanges determine the actual installed operating point.

Installation and System Requirements

Verify a compatible 1-1/2-inch flanged piping arrangement before ordering this circulator. Compare required loop flow and total head with the applicable Taco performance curve, then review water temperature, pressure, electrical supply, and installation space. Support nearby piping so its weight does not load the pump body. Follow Taco documentation for mounting, wiring, startup, and service procedures for the exact 0012-SF4-2 configuration.

Why Choose the Taco 0012-SF4-2

This model combines a stainless-steel body, 1-1/2-inch flanged port, and 1/8 HP motor for documented commercial hot-water recirculation use. Its 45 GPM maximum flow and 13-foot maximum head provide initial selection boundaries. Buyers should compare those limits with the actual loop curve, existing piping connection, water conditions, and required circulation rate before confirming the pump configuration.

Warranty and Support

Taco 00 Series circulators carry a 3-Year Limited Warranty from the manufacturer date code. Taco states that a product proven defective under normal use may be repaired or replaced under its warranty terms. Coverage remains subject to current conditions and exclusions. Mulmotor provides pre-purchase product guidance and order-related customer support. Confirm that the ordered 0012-SF4-2 configuration is covered under current Taco documentation before purchase.

Before Ordering the Taco 0012-SF4-2 Stainless Steel Circulator

Before ordering, confirm that your commercial hot-water recirculation loop uses a 1-1/2-inch flanged connection. You should compare required flow and head loss with the published 45 GPM and 13-foot maximum limits using the relevant Taco curve. Review water temperature, system pressure, electrical requirements, mounting space, and pipe-support needs. Confirm that the stainless-steel body meets the documented project material requirement before purchase.
