Century Pump Motor, Up Rated, 1.5 HP, 115/230V, UST1152

The Century UST1152 is a 1.5 HP up rated replacement pool pump motor with a 1.00 service factor, wired for 115V or 230V. It is listed as the replacement motor for Hayward Super Pump 1600X and 2600X series pumps, and it also appears in the Hayward Super II parts diagram.

Up rated, and what that means

Up rated and full rated describe how a motor states horsepower against its service factor, not how much water it moves. This one is 1.5 HP at a 1.00 service factor. What matters when you replace a motor is that the rating and the service factor match what came off the pump, so the impeller and the motor stay a matched pair.

Cross references

The same motor is carried under several numbers. Substitute part numbers on record are ST1610Z1M, 5PE50 and C48L2N134 AOS, which is useful if the old label is unreadable or the pump has been through a previous repair.

Motor only

This is the motor by itself. The mechanical seal has to be replaced any time the motor comes off, and it is not included here. A Super Pump rebuild kit covering the seal and the wet end gaskets is available separately, and doing both at once saves opening the pump twice.
