Frequently asked questions

Common questions about ARMSTRONG Circulator Pumps from 3G Electric.

How do I size an ARMSTRONG circulator pump for my system?

Sizing requires the required flow rate (GPM) and total head loss (feet) of your hydronic loop. Check the pump curve for the model you are considering, and verify motor horsepower and voltage. For intelligent inline models, review the control features for variable-speed operation. Contact 3G Electric for help matching specifications.

Are ARMSTRONG circulator pump parts interchangeable with other brands?

ARMSTRONG impellers, motors, and bearing assemblies are designed for specific ARMSTRONG pump models. While some components may be dimensionally similar to other brands, using genuine ARMSTRONG parts ensures proper fit and performance.
