MP Pumps 21588 Seal
A mechanical or shaft seal keeps pumped fluid from leaking out along the pump shaft while allowing the shaft to rotate freely. Seal faces wear over time and are a common source of pump leaks.
Always match by the MP Pumps part number 21588 listed on your equipment parts diagram, since dimensions and material vary across the MP Pumps lineup even for parts with the same common name.

Most MP Pumps wet-end parts install with standard hand tools. Always relieve system pressure and disconnect power before servicing a pump.
Q: Can I use this part on a different MP Pumps model?
Wet-end parts are sized to a specific pump model and configuration. Confirm against your pump nameplate before ordering, or send us a picture and we will verify.
