The PM500 is magnetically driven pump, with no shaft seal. The pump is epoxy encapsulated, which allows the PM pump to run fully submerged in many liquids or in open air for complete moisture protection. When re-assembling the pump for service, make sure all “O” Rings are properly seated. See the repair parts list for a breakdown of replacement parts.
