💧 Mtr, Cent, 1.5Hp, 115/230V, 1-Sp, Sf1, 48Yfr
Made by Century, manufacturer part number UQC1152.
⚠️ Energy regulations: please read
Since 29 September 2025, US Department of Energy rules have required newly made replacement pool pump motors of 1.15 to 5 total horsepower to be variable speed. This is a single-speed motor. Motors built before that date can still be sold and installed until stock runs out, so supply of this motor will end.
Some states, including California, have stricter rules that may not allow a single-speed replacement. Check your local regulations before ordering.
A variable-speed motor also costs much less to run. If you would rather upgrade, check the mounting, shaft and total horsepower of your pump against our variable-speed motors before ordering.
Century replacement pool pump motor – 1-1/2 HP, 115V / 230V, single speed, 48Y frame
⚙️ What this motor is
This is a replacement motor only, not a complete pump. It is a square flange motor, which you can recognise by a square plate on the pump end with a bolt through each corner. It is a 48Y frame with a threaded shaft. It runs on 115V / 230V, single speed. It bolts to the wet end you already have, so the pump housing, impeller and plumbing stay where they are.
✅ Check these before you order
- Compare total horsepower, not nameplate horsepower. Multiply the horsepower on your old motor’s label by the service factor printed next to it. This one is 1.65 HP total. Two motors labelled differently can be the same motor once you do that sum.
- Mounting. Square flange, C-face and thru-bolt motors are not interchangeable and there is no adapter between them, so check yours matches before ordering.
- Frame size. Measure across the round body of the motor: roughly 5-1/2 to 5-7/8 inches is a 48 frame, roughly 6-1/2 to 6-3/4 inches is a 56 frame. Measuring beats reading the old label, because some makers labelled 48 frame motors as 56. This one is a 48Y frame.
- Shaft. This motor has a threaded shaft. A threaded shaft has the impeller screwed straight onto it; a keyed shaft is smooth with a groove down it. The two are not interchangeable.
- Voltage. This motor is 115V / 230V. Read it off the old motor’s label rather than assuming from the wiring – a spa wired for 240V can still run a 120V pump.
🔧 When you fit it
- Fit a new shaft seal at the same time. A failed shaft seal lets water into the motor and is the most common reason a motor dies. Reusing the old one on a new motor is the quickest way to ruin it.
- Rotation. Pool and spa motors turn counter-clockwise seen from the shaft end, shown on the label as CCW or CCWPE. They cannot be reversed by swapping wires, so check the old label if it says anything different.
- Keep the horsepower the same unless you are changing the impeller too – the impeller is matched to the motor’s output.

Find the right pump or motor
Enter what is printed on the label of the one you are replacing. Anything that differs is shown with the difference spelled out, so you can judge it for yourself.
Port size is the plumbing thread, not the pipe — a 2 inch union measures about 3 inches across the male thread. Amps are compared to within half an amp, since published figures round differently between motor brands. Voltage is never treated as a near miss: a 115V motor is not one step from a 230V supply. Anything whose page does not publish a figure you entered is left out rather than offered with a caveat — search it by name to see it anyway.
