This end suction pump incorporates a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft paired with a bronze shaft sleeve to maintain the dry shaft configuration. A mechanical seal utilizes a ceramic seat and EPT rubber to prevent leakage. Engineered for system operation up to 125 PSI, the construction excludes a wear ring. The assembly accommodates maintenance activities without system piping removal, utilizing pressure tappings on the suction and discharge connections.
This unit utilizes a 7.5 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.45. 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
