This end suction pump utilizes a class 30 cast iron casing with a center-line discharge for positive air venting. The assembly integrates a bronze impeller dynamically balanced to ANSI Grade G6.3 and a stainless steel shaft protected by a replaceable bronze shaft sleeve. A dry shaft design eliminates contact between the circulating fluid and the shaft. The mechanical seal incorporates ceramic seats and EPT rubber, rated for 125 PSI. Gauge ports at the suction and discharge connections allow for system pressure monitoring.
This 5 HP Premium Efficiency TEFC 1750 RPM motor includes Aegis Grounding and operates on 200-230V / 3PH power with a DOE PEI of 0.44. 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
