This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid movement. The internal assembly incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve and a dry shaft design that prevents contact between the shaft and circulating fluid. A ceramic and EPT mechanical seal maintains system integrity under operating pressures up to 125 PSI. The pump is constructed with integrated gauge ports at both the suction and discharge connections to monitor hydraulic performance.
The 50 HP Premium Efficiency TEFC 3450 RPM motor incorporates Aegis shaft grounding and operates on 380-460V / 3PH power. 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-mech bypass, main disconnect, and 5kA SCCR and holds an enclosure NEMA Type 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
