This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The pump utilizes a dry shaft configuration that isolates the stainless steel shaft from circulating fluids and includes a replaceable bronze shaft sleeve. It integrates a 125 PSI pressure rating and a replaceable bronze wear ring. The mechanical seal design uses a ceramic seat half with Buna rubber components to maintain system integrity. Pressure tappings are present on both the suction and discharge connections to facilitate system monitoring.
The 20 HP Premium Efficiency ODP motor operates at 3450 RPM and incorporates Aegis Grounding for protection, utilizing a 200-230V / 3PH power supply with a DOE PEI rating 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.
