I have a pac-fab challanger model 35-5460. It is high flow, or high pressure pump? I believe that this line of pumps is not made by Pentair.
Here is what I know about the pump:
Motor: Century Centurion
SF=1.1 (Service Factor)
230 VAC, 10A
1081 Pool Pump duty mount horizontal with vent holes down
PAC-FAB Challenger 2HP
Pump Housing: Part #: 35-5460
