The D-402823 Mechanical Seal is a quality pump shaft seal designed to prevent water leaking along the shaft into the pump motor. This seal is made up of a 5/8″ booted cup with a 3/4″ carbon face, providing reliable sealing performance in pool and spa pump applications.
Commonly used in Davey Starflo and Sureflo pumps, this mechanical seal is ideal for pump servicing, rebuilds, and repairing leaks between the wet end and motor. A worn seal is one of the most common causes of pump motor damage and bearing failure.
Manufactured with durable sealing materials, the D-402823 seal is built to handle heat, pressure, and pool/spa chemical environments. Replacing a faulty mechanical seal helps restore pump reliability, prevent corrosion, and extend motor life.
