When To Use This
Pro Tip
Never reuse an old mechanical shaft seal when installing a new motor; even microscopic wear on the old seal face will leak water down the shaft and destroy the front motor bearing within months.
Common Questions & Instructions
What are the signs that my existing pool pump motor needs replacement?
A loud humming sound without starting, high-pitched screeching bearing noise, frequent circuit breaker tripping, or casing corrosion indicate internal electrical or mechanical failure.
Can I install this Centurion Pro motor myself or do I need a technician?
While intermediate DIYers can perform the swap, it requires high-voltage wiring and precise shaft seal installation. Always replace the mechanical seal to avoid water damage to new bearings.
How do I ensure the motor is wired for the correct voltage?
Inspect the terminal diagram on the rear motor nameplate. The motor typically arrives set for 230V and requires adjusting the voltage selector connector prior to powering up on a 115V line.
