This base-mounted end suction pump comprises a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly incorporates a dry shaft design that utilizes a stainless steel shaft covered by a replaceable bronze shaft sleeve to prevent fluid contact. A mechanical seal with a ceramic seat and EPT rubber components maintains system integrity at pressure levels up to 125 PSI. The volute housing contains integral mounting feet and provides center-line discharge for air venting.
Powered by a 20 HP premium efficiency ODP motor operating at 1750 RPM, the assembly integrates Aegis grounding for protection against electrical discharge and accepts 208V 3PH power, resulting in a DOE PEI rating of 0.46. 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 an electro-mechanical bypass and a fused main disconnect while holding a NEMA Type 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
