Armstrong 410135-340 Circulating Pump 707T Bronze Impeller

Description

Corrosive commercial heating loops use Armstrong 410135-340 707T for three-phase circulation and material-conscious pump selection. Its 1/2 HP motor accepts 208 to 230 or 460 V, while the cast iron body, bronze impeller, bronze sleeve, and approximate 70 GPM capacity support commercial heating service. Confirm the approximate 32-foot head, water chemistry, phase rotation, and system curve before startup.

The Armstrong Series 700 707T Bronze Fitted uses oil-lubricated sleeve bearings and a bronze non-ferrous impeller within a cast iron body. Its approximate 70 GPM and 32-foot head provide selection references, while verified data does not include amp draw, RPM, seal material, connection size, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the commercial heating duty point before installation.
