Motors
All jet pump motors are totally enclosed and fan-
cooled design for quiet operation and superior protec-
tion in harsh environments. Stainless steel motor shaft
offers excellent corrosion resistance. Double, oversized
greased ball bearings are maintenance-free sealed for
life. All motors have built-in thermal overload protec-
tion and are capacitor-run, with no switches to fail.
Drive end motor bearing protected by durable lip seal.
