Oberdorfer 32585 Mechanical Seal – Viton Replacement Part
This is the genuine Oberdorfer 32585 seal in Viton (fluoroelastomer). Seal leakage is the single most common reason an otherwise sound Oberdorfer pump comes out of service, and it is also the cheapest fault to put right if it is caught while the pump is still only weeping.
Seals fail from dry running, from abrasives in the pumped fluid, from heat, and from simple hours. A pump that has been run dry even briefly will often have a scored seal face that weeps from then on, which is why Oberdorfer is emphatic that its pumps are not to be run dry.
Press it square into the bore using a tool that bears on the outer edge, never on the face. A seal that goes in cocked will leak from the first hour.

Frequently Asked Questions
Q: Should the bearing be replaced at the same time?
If the seal has been leaking for a while, inspect the bearing closely. Fluid that has reached it usually means it is on borrowed time.
Q: What makes a new seal leak straight away?
Almost always a cocked installation, a scored shaft, or a face that was contaminated during assembly. Check all three before blaming the part.
Q: Can the pump be run briefly without liquid?
No. Dry running destroys seal faces in seconds, and it is the fastest way to ruin a freshly rebuilt pump.
Q: Does the pumped fluid change which seal I need?
Yes. The elastomer grade has to be compatible with the fluid and its temperature, so confirm the grade against what the pump actually handles.
