Taco kp2038d Cast Iron Pump Casing 3x3x6 125

Product Description

The TACO kp2038d is a cast iron pump casing designed for use in hydronic heating systems. This casing houses the pump internals and maintains the pressure boundary within the circulator assembly. With a 3x3x6 port and 125 pressure rating configuration, it is a structural and functional component that directs fluid flow through the system. Licensed HVAC technicians and plumbing professionals typically handle installation and replacement of this component during circulator service or system upgrades. The cast iron construction provides durability in wet, pressurized hydronic environments where corrosion resistance and dimensional stability are essential.

This casing is suited for residential and light commercial hydronic heating applications, including hot water baseboard systems, radiant floor loops, and other closed-loop circulating systems. It is installed as part of a circulator pump assembly where the casing body interfaces with the pump volute, impeller, and flange connections. Replacement is typically required when the original casing shows cracking, seal failure, or significant erosion from system sediment. Taco Comfort Solutions manufactures this component to support ongoing serviceability of their circulator pump lines.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with hydronic system service. Shut down the boiler and isolate the circulator using system shutoff valves before disassembly, and allow the system to depressurize and cool fully prior to handling. Follow local plumbing codes and manufacturer torque guidelines when reassembling flange connections and pump hardware. Inspect all gaskets and seals before reassembly to prevent system leaks after startup.
