Armstrong Fluid Technology 110223-306 Pump

The Armstrong Fluid Technology 110223-306 is a high-performance Astro 230SS wet rotor circulator engineered for efficiency in potable water systems and hydronic heating applications. Constructed with a lead-free stainless steel body, this 3-speed circulator pump provides exceptional corrosion resistance, making it an ideal choice for open-loop domestic water recirculation and solar heating systems. This model is a direct, advanced replacement for the obsolete 110123-006 (Astro 30B), featuring a versatile flanged connection compatible with 3/4", 1", 1 1/4", or 1 1/2" flanges to match various piping requirements.

Operating on 115Vac single-phase power, the Astro 2 Series pump delivers a maximum flow of 18 GPM and up to 18 feet of head. Its maintenance-free design utilizes a ceramic shaft and bearings lubricated by the system fluid, eliminating the need for mechanical seals or external lubrication. The integrated three-speed switch allows installers to fine-tune performance to meet specific system head and flow demands, optimizing energy consumption. For simplified installation, this unit includes a pre-installed, high-flow check valve and a convenient plug-in terminal strip for rapid electrical wiring.

• Corrosion-Resistant Construction: Lead-free stainless steel volute ensures safety and longevity in potable water and open-loop systems.
• Customizable Performance: Three field-selectable speeds allow for precise matching of system requirements, reducing energy waste and noise.
• Maintenance-Free Operation: Wet rotor technology with ceramic components eliminates the need for periodic lubrication or seal replacements.
• Easy Air Purging: Includes a built-in vent plug to quickly remove trapped air from the system during initial startup.
• Universal Compatibility: Standard flange-to-flange dimensions facilitate the seamless replacement of competing fixed-speed models.

Is the Armstrong 110223-306 suitable for drinking water?
Yes, the stainless steel construction of the Astro 230SS is NSF-372 certified lead-free, specifically designed for domestic potable water applications.

Does this pump include the flanges needed for installation?
No, flanges are sold separately. This unit features a standard 2-bolt flanged connection compatible with multiple sizes ranging from 3/4" to 1 1/2".

Can I use this to replace a Taco 007 or Grundfos UP15-42?
Yes, the Armstrong 110223-306 is a versatile cross-reference for many popular fixed-speed models. Its 3-speed functionality allows it to replicate the performance curves of various competing circulators.
