This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The pump utilizes a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This assembly incorporates a mechanical seal utilizing tungsten carbide seat halves and EPT rubber to support pressures up to 250 PSI. The design includes a replaceable wear ring along with suction and discharge pressure tappings to facilitate system monitoring and maintenance without disturbing the piping.
The 50 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.46. The 'S' in the SCI 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.
