Taco 1911dae10131292* Close-coupled In-line Pump 0.33 Hp

Product Description

The TACO 1911dae10131292* is a close-coupled in-line circulating pump designed for hydronic heating and cooling systems. It features 1-1/2-inch suction and 1-1/2-inch discharge ports in a true in-line configuration, reducing piping stress and simplifying installation. The stainless steel casing and 4-3/4-inch stainless steel impeller pair with a cast iron bracket and bronze wear ring for durability in demanding service. A 1/3 HP ODP motor runs at 1750 RPM on 115/208-230 volts, single-phase, 60 Hz power. Licensed HVAC and plumbing contractors install this pump in commercial and residential hydronic applications where in-line placement, easy serviceability, and reliable long-term operation are required.

This pump is suited for closed-loop hydronic heating and cooling systems, building services circulation, and similar fluid-handling applications. It handles fluid temperatures up to 250 degrees F, making it appropriate for high-temperature hot water systems. The rear pull-out design allows the motor and rotating assembly to be removed for service without breaking into the piping. The unit can be installed in horizontal or vertical orientations without external strapping, offering layout flexibility in mechanical rooms and tight spaces.

Key Features

• In-line 1-1/2-inch suction and discharge ports reduce piping strain and simplify system layout
• Stainless steel casing and impeller with bronze wear ring resist corrosion in hydronic service
• Mechanical seal uses ceramic seat, carbon rotor, and EPT rubber elastomers for long service life
• Rear pull-out design allows motor and rotating component removal without disturbing connected piping
• Integrated pressure tappings support differential pressure readings across the pump
• Permanently sealed, grease-lubricated motor ball bearings support maintenance-free operation
• Companion flanges included for direct connection to standard piping

Compatibility

Designed as an OEM-style close-coupled in-line pump for the TACO 1900 Series, suitable for residential and light commercial hydronic heating and cooling piping systems.

Installation Notes

Installation should be performed by a licensed plumber or HVAC mechanical contractor in accordance with applicable local codes and ASHRAE hydronic system guidelines. Shut off and isolate the system, depressurize, and allow fluid to cool before removing or installing the pump. Verify that supply voltage and phase match the motor nameplate before energizing. The rear pull-out design simplifies field service, but always confirm the isolation valves are fully closed and the system is de-energized before pulling the rotating assembly.
