This base-mounted end suction pump incorporates a class 30 cast iron casing with center-line discharge and a bronze impeller dynamically balanced to ANSI Grade G6.3. The assembly utilizes a dry shaft design that protects the stainless steel shaft from contact with circulating fluid through a replaceable bronze shaft sleeve. For operational sealing, it employs a ceramic mechanical seal with EPT rubber and allows for a maximum pressure rating of 125 PSI. The casing integrates a replaceable bronze wear ring, along with pressure tappings on suction and discharge connections for system monitoring.
This unit utilizes a 25 HP, Premium Efficiency, ODP, 1750 RPM motor with Aegis grounding and a 200-230V, 3PH power supply, resulting in a DOE PEI 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 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.
