Taco 003 Circulator Pump

The Taco 003 Series is an industrial-tier, ultra-low-flow inline circulator pump purpose-built for continuous domestic hot water recirculation, heat recovery systems, and solar thermal loops. Engineered specifically to deliver low-velocity fluid movement, the 003 eliminates the risk of pinhole pipe erosion in copper lines while providing quiet, immediate hot water delivery across residential and commercial plumbing grids.

Designed for High Reliability Potable Water Systems:

• Corrosion-Resistant Fluid Paths: Available in premium bronze or stainless steel construction, ensuring total safety and compliance with strict lead-free potable water mandates while preventing oxidization.
• Self-Lubricating Cartridge Assembly: Houses all dynamic internal rotating parts—including the rotor, shaft, and ceramic sleeve bearings—within an isolated drop-in internal module. System water continuously self-lubricates the bearing track, lowering audible noise and eliminating manual oiling.
• High-Efficiency Power Footprint: Designed with a low-amperage permanent split capacitor (PSC) motor matrix that draws minimal wattage, allowing for highly economical 24/7 continuous duty or timer-controlled operation profiles.

In-Line Servicing Efficiency: Featuring Taco's signature 4-bolt modular layout, the internal cartridge core can be extracted and completely swapped out in minutes without unseating the pump body casing from the main plumbing manifold or requiring pipe alterations.
