This end suction pump utilizes a class 30 cast iron casing with integral mounting feet and a center-line discharge. The unit integrates a dynamically balanced bronze impeller, a stainless steel shaft, and a replaceable bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft. A mechanical seal with a ceramic seat and EPT rubber components maintains system integrity at 125 PSI. Gauge ports and a casing drain port facilitate maintenance without disturbing system piping.
The motor is a 7.5 HP premium efficiency TEFC unit operating at 1750 RPM with Aegis grounding on 200-230V / 3PH power, yielding a DOE: PEI = 0.45. The "S" in the 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.
