Sta-Rite ZBR39020 Mechanical Seal Kit
This is the ZBR39020 mechanical seal kit. A leaking shaft seal shows up as water dripping from underneath the pump, near where the motor meets the pump body, while the pump is running or just after it shuts off.
Shaft seals wear from normal use, from a pump that has been run dry even briefly, and from grit in the water that gets between the two faces. Handle the sealing faces by their edges only during installation, since a fingerprint or a speck of grit on the polished face can cause a leak from day one.

Frequently Asked Questions
Q: Should I replace the impeller when I replace this seal?
Not always, but inspect it while the pump is open, since the two parts often wear under the same conditions.
Q: Will this fit a different pump in the same series?
Match the exact part number on the old seal rather than assuming similar-looking pumps share the same size.
Q: Is it safe to keep running the pump with a small seal leak?
Not for long. A small drip can progress and eventually let water reach the motor windings, turning a low-cost seal replacement into a motor or full pump replacement.
Q: How do I know my shaft seal is leaking?
Water dripping from underneath the pump, at the joint between the motor and the pump body, while it runs or right after it shuts off is the classic sign of a worn shaft seal.
