Pump oil mister

A motor driven pump comprising:

• a motor driven pump shaft connected to a motor at one end thereof;
• first and second coaxially aligned pump shaft bearing assemblies surrounding and rotatably supporting said pump shaft, said first and second bearing assemblies being spaced apart from one another along said pump shaft;
• a main lubrication chamber disposed along said pump shaft adjacent and between said first and second pump shaft bearing assemblies, said main lubrication chamber housing lubricating fluid for lubricating said first and second bearing assemblies disposed adjacent said main lubrication chamber;
• a lubricating fluid dispenser affixed to said pump shaft for rotation therewith, said dispenser being disposed within said main lubrication chamber substantially entirely above the lubricating fluid level and between said first and second pump shaft bearing assemblies, and wherein said dispenser when rotated along with said pump shaft creates an air-flow within said main lubrication chamber which causes said lubricating fluid to be dispersed throughout said main lubrication chamber so as to continually lubricate said first and second bearing assemblies as said pump shaft is rotated by said motor, the positioning of said dispenser substantially entirely above the lubricating fluid level reducing heat generation within said main chamber so as to allow said first and second bearing assemblies to run at reduced temperatures so as to prolong the operating life of the assemblies.

A motor driven pump comprising:

• a pumping chamber in which fluid to be pumped is pumped between a fluid inlet and a fluid outlet;
• a motor for driving a shaft having first and second ends, said first end affixed to said motor and said second end connected to a fluid pumping impeller, said impeller being disposed within said pumping chamber for pumping said fluid to be pumped from said fluid inlet toward said fluid outlet;
• a main lubrication chamber housing a lubricating fluid disposed along said shaft, said lubricating fluid for lubricating a shaft bearing assembly rotatably supporting said shaft, said bearing assembly disposed adjacent said main chamber;
• a dispenser affixed to said shaft within said main lubrication chamber for rotation therewith, said dispenser for dispersing said lubricating fluid housed in said main lubrication chamber throughout said main chamber and toward the inner side of said shaft bearing assembly, said inner side facing said dispenser;
• a lubricating fluid circulatory passageway interfacing said main lubrication chamber with an auxiliary lubrication chamber, said auxiliary chamber for allowing said lubricating fluid therein to lubricate the outer side of said shaft bearing assembly, and wherein said circulatory passageway permits said lubricating fluid to make its way from said main lubrication chamber to said auxiliary lubrication chamber disposed adjacent the outer side of said shaft bearing assembly so that both the inner and outer sides of said shaft bearing assembly are simultaneously lubricated by said lubricating fluid within said main and auxiliary lubrication chambers respectively thereby providing improved bearing lubrication and reduced friction so as to prolong the operating life of said bearing assembly;
• an inclined return passageway for permitting the lubricating fluid to flow from said auxiliary chamber back into said main chamber;
• and
• wherein the lubricating fluid level within said main lubricating chamber is located entirely below both bearing balls of said bearing assembly and a portion of said bearing assembly which rotates along with said shaft so as to reduce heat generation caused by rotation of said shaft and bearing balls.
