Pump purpose and fit

The Taco 2400-40S is a flanged circulating pump built for potable-water systems. It serves hydronic heating loops, domestic hot-water recirculation and similar closed-loop duties where a standard single-speed unit is specified.

Pipework and electrical checks

Verify that the existing flanges match the 1 1/4 in and 1 1/2 in intake sizes and the 8 1/2 in face-to-face dimension. Confirm the supply is single-phase 115/230 V AC and that the circuit can deliver 1.0 A at 115 V or 1.9 A at 230 V.

System integration

The pump develops a maximum head of 19 ft and delivers 26 gpm at 10 ft or 16 gpm at 15 ft of head. Its EPDM body gasket suits potable water, and the single-speed 1/6 hp motor runs directly on line voltage without a separate controller.

Questions about this item

Does the pump come with the flanges and gaskets needed for installation?

The pump body includes an EPDM gasket; flanges are not supplied and must be purchased separately to match the 1 1/4 in or 1 1/2 in pipe size.

How do I decide between the 1 1/4 in and 1 1/2 in intake options?

Choose the size that matches the existing piping in the system — both flange sizes are supported by the same pump body.

What flow can I expect at 15 ft of head in a typical hydronic loop?

At 15 ft of head the pump delivers 16 gpm; at 10 ft of head it delivers 26 gpm.
