ABSTRACT:
An environmentally leak-proof pump is provided including: an environmentally leak-proof motor housing having located therein a motor for rotatably driving a rotating shaft; a piston seal axially forward of the motor; and an oil misting chamber disposed between the motor and the piston seal, the misting chamber for simultaneously providing lubrication to two coaxially disposed spaced apart bearings. The oil mister (34) includes a dispenser (260) fixed to a rotating shaft (23), the dispenser having a plurality of nozzles formed by bores (262 and 263) on opposing sides of the dispenser body. Each bore communicates with a passageway (264) thus allowing each nozzle to continuously direct a flow of lubricating liquid or mist toward adjacent bearings (35 and 36).
