This end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. A mechanical seal with a ceramic seat and EPT elastomer maintains pressure integrity up to 125 PSI, and the internal design includes a replaceable bronze wear ring.
The 20 HP premium efficiency ODP motor operates at 3450 RPM and incorporates Aegis grounding for 200-230V / 3PH power supply, with a DOE PEI rating 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 Type 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
