Armstrong 410133-201 Circulating Pump 702S

Description

Small zone heating systems use Armstrong 410133-201 702S for residential hydronic circulation with a 115 V single-phase motor. Its 1/12 HP drive operates at 1725 RPM through a cast iron body, alloy steel shaft, and standard mechanical seal. Purge the heating loop, verify the two-bolt flange connection, and support the piping before startup to prevent air-related noise and seal wear.

The Armstrong Series 700 702S uses a single-phase 115 V motor and a three-piece in-line circulation design with a cast iron body. Its alloy steel shaft transfers motor power through the pump assembly, while the standard mechanical seal contains the circulating fluid. Verified data does not include GPM, maximum head, amp draw, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so confirm the replacement curve and mounting details before installation.
