This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller. The design incorporates a dry shaft to prevent circulating fluid from contacting the stainless steel shaft, which is covered by a replaceable stainless steel sleeve. Mechanical sealing is achieved with ceramic seat halves and Viton rubber. This unit is rated for 125 PSI operation and includes a wear ring. Center-line discharge construction allows for positive air venting, while gauge ports accommodate pressure monitoring.
This assembly utilizes a 40 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding on a 200-230V 3PH supply, achieving a DOE PEI rating of 0.47. 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.
