This end suction pump is constructed with a cast iron casing and integrally cast mounting feet rated for 125 PSI operation. The assembly incorporates a bronze impeller balanced to ANSI Grade G6.3 and a stainless steel shaft protected by a replaceable bronze shaft sleeve. This dry shaft configuration prevents the circulating fluid from contacting the shaft during operation. The mechanical seal utilizes a ceramic seat and EPT components to maintain system integrity.
The pump operates with a 15 HP premium efficiency TEFC motor at 3450 RPM, equipped with Aegis grounding for 380-460V / 3PH power supply, achieving a DOE PEI rating of 0.45. 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
