Century replacement pool pump motor – 5 HP, 230V / 460V, single speed, 182JMZ

⚙️ What this motor is

This is a replacement motor only, not a complete pump. It is a 182JMZ frame motor. It runs on 230V / 460V, single speed. It fits the wet end you already have, so the pump housing 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 next to it, and compare that figure. This motor is rated 5 HP.
• 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 182JMZ frame.
• Voltage. This motor is 230V / 460V. 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.
