The HZ221 Honeywell STG HT Pump W/ AUX HT is a high-performance zone pump designed for use in residential and commercial HVAC systems. This pump is part of Honeywell's reliable and efficient STG (Sensitive Turbine) series, which is known for its durability and energy efficiency.
The HZ221 is a dual-stage pump, meaning it has two impellers that work in tandem to provide a consistent and powerful flow of liquid.

The HZ221 is constructed with high-quality materials, including a corrosion-resistant stainless steel casing and a ceramic shaft, to ensure long-lasting performance and reliability. The pump also features a easy-to-use, rotary union-free design, which reduces maintenance requirements and increases overall system efficiency.
In addition, the pump has a built-in check valve to prevent backflow, and it is compatible with a wide range of HVAC liquids, including water, glycol, and propylene glycol. The pump also includes a mounting bracket for easy installation and a drain port for easy maintenance.
