The PM500 is a fully submersible and magnetically driven seawater circulation coolant pump. There is no shaft seal. The pump is epoxy encapsulated, which allows the PM500 series pumps 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.
