Armstrong Fluid Technology 116443MF-136A Pump
The Armstrong Fluid Technology 116443MF-136A is a high-performance circulator pump designed for reliable fluid handle in sophisticated HVAC systems. As a direct replacement for the legacy 116443-136 model, this three-phase pump features a 1/2 HP motor compatible with 208-230/460Vac power supplies. Engineered with a durable cast iron body and a corrosion-resistant non-ferrous impeller, the Armstrong H53BF ensures long-term operational stability in hydronic heating and cooling applications. The maintenance-free bearings eliminate the need for manual lubrication, significantly reducing downtime. Its three-piece design allows for a "back pull-out" capability, meaning the pump body can remain in-line during servicing to simplify repairs. Designed for use with 1 1/2" flanges, this centrifugal pump provides an efficient booster pump solution for multi-stage zoning and industrial fluid transfer. Whether you are managing domestic water systems or complex industrial loops, this unit delivers consistent flow and energy-efficient performance.
Key Benefits
- Maintenance-Free Operation: Features permanently lubricated maintenance-free bearings, removing the need for seasonal oiling or grease.
- Serviceability: The radially-split body and modular three-piece design allow for quick component replacement without disconnecting system piping.
- Durable Construction: Built with a rugged cast iron body and an oversized alloy steel shaft for maximum durability in high-demand environments.
- Versatile Compatibility: Operates on three-phase power with dual-voltage support, making it suitable for a wide range of commercial and industrial electrical setups.
- Smooth Flow: The precision-balanced non-ferrous impeller ensures maximum water delivery and quiet operation within the HVAC system.
Common Questions
Is this pump compatible with my existing Armstrong H-53 series?
Yes, the 116443MF-136A is the official maintenance-free replacement for the older 116443-136 version. It maintains the same physical footprint and electrical requirements.
Can this pump be used for potable water systems?
This specific model features a cast iron body and is intended for closed-loop hydronic heating and cooling. For potable water, a lead-free bronze or stainless steel model is typically required.
What should I do if the pump is noisy or vibrating?
Common causes for noise include air in the system, improper pump alignment, or issues with the resilient motor mounts. Ensure the 1 1/2" flanges are securely bolted and the system is properly bled.
Does this unit come with the mounting flanges?
While this pump is designed for 1 1/2" flanged connections, please verify with our team if a specific flange kit is included in your current package or if it must be ordered separately.
