Armstrong 174033MF-013 S-35 Cast Iron Pump 1/6HP

Description

Apartment heating systems use Armstrong 174033MF-013 S-35 for commercial boiler circulation and residential building hydronics. Its 1/6 HP, 115 V single-phase motor operates at 1750 RPM, delivering approximately 55 GPM against approximately 16 feet of head. Confirm the cast iron body, copper sleeve, flexible spring coupler, and resilient-mounted ODP motor before startup.

The Armstrong Series S S-35 uses a cast iron body, alloy steel shaft with copper sleeve, and flexible spring coupler. Its approximate flow and head values guide system matching, while the 115 V motor supports compatible single-phase service. Verified data does not include amp draw, seal type, connection size, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so confirm the final pump documentation.
