E-Flo Plus Electric Circulation Pumps
Check your pump’s identification plate (ID) for the 6-digit part number of your
pump. Use the following matrix to define the construction of your pump, based
on the six digits. For example, Pump Part No. E P 2 1 6 0 represents electric
power (E), pump (P), 230/460V motor (2), sensor circuit installed (1), and 2000
cc Maxlife lower (6). The last digit (0) is unassigned. To order replacement
parts, see the Repair-Parts manual 311594.
