Engineering Data

Diagrams illustrate the physical layout of the 9EC Series pumps: 9EC-CIA-SFS, 9EC-CIA-RF, and 9EC-CIM. Each diagram features labels A, B, and C pointing to specific dimensions, with a 115 VOLT PLUG indicated. A separate table provides the precise measurements for dimensions A, B, and C for each model.

Model	A	B	C
9EC-CIA-SFS	11.8" (30 cm)	10.7" (27.1 cm)	8.4" (21.4 cm)
9EC-CIA-RF	11.0" (28 cm)	8.9" (22.6 cm)	8.4" (21.4 cm)
9EC-CIM	11.0" (28 cm)	8.9" (22.6 cm)	8.4" (21.4 cm)

Performance Data

The 'PERFORMANCE DATA' section presents a graph illustrating pump performance. The vertical axis ('Total Dynamic Head in Feet') ranges from 0 to 45, with a corresponding metric axis ('Total Dynamic Head in Meters') from 0 to 12. The horizontal axis ('Flow/Capacity in US Gallons Per Minute') ranges from 0 to 80, with a corresponding metric axis ('Flow/Capacity in Liters Per Minute') from 0 to 300. A single performance curve shows the relationship between flow rate and head pressure.
