This end suction pump utilizes a class 30 cast iron casing with center-line discharge and integrally cast mounting feet. The assembly incorporates a bronze impeller dynamically balanced to ANSI Grade G6.3. A dry shaft design prevents contact between the circulating fluid and the shaft, which is constructed of stainless steel and covered by a replaceable bronze shaft sleeve. The mechanical seal consists of EPT rubber and a ceramic seat, providing a pressure rating of 125 PSI. Heavy-duty, permanently lubricated ball bearings are housed within the cast iron bearing assembly, which includes a foot support at the driver end.
The motor provides 75 HP at a premium efficiency rating, housed in a TEFC enclosure, operating at 1750 RPM with Aegis grounding and a 380-460V, 3PH power supply. The S in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
