ABSTRACT:
A hand carried, motor driven pump which will pump at high or low pressure, depending upon the size of the plunger used. The pump is used for high pressure lubricant, up to 9,000 lbs., to a high volume of fluid, such as Diesel oil, water and the like at low pressure. The pump is used in practically all industries in which machinery is to be lubricated by grease under high pressure and where liquids need to be transferred or pumped from one container to another. The present pump is particularly adaptable for use on heavy agricultural machinery, where portability is essential.
