Pentair replacement pool pump motor – 115V / 230V, single speed

⚙️ 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 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

• 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.
• 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.
• Height. The capacitor sits in a raised hump on top of this motor, so measure your clearance if it sits under a spa skirt or below low plumbing.

🔧 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.
