The 1-quart-per-stroke dispensing pump Model 506-1011 (NSN 4930-00-287-8293) is used chiefly to transfer lubricating oil. The pump can be attached to a 55-gallon drum or a 600-gallon tank. This pump consists of a pump assembly, a suction pipe, and a discharge tube. It can be installed in a 1 ½1/2- or 2-inch drum opening and on the 600-gallon, skid-mounted tank. The piston is raised and lowered by a gear-and-rack mechanism which is driven by a crank handle. Turning the handle to make one complete stroke of the piston delivers 1 quart of product. The handle must then be returned to its original position before more product can be delivered. The pump has an adjustable stop so that it does not deliver too much or too little product. Product is delivered through a nozzle, which is positioned to connect with an adjustable swing arm return tube. The return tube lets excess product drain back into the drum through a channel located in the pump base. If the work area is not under cover, the pump suction pipe and the drum vent plug must be tightened securely and protected with a waterproof cover when the pump is not in use. This keeps water from seeping through the drum openings and contaminating the product.This pump is used chiefly to transfer lubricating oil from 55-gallon drums to smaller containers. NEW, COMPLETE. Govt Issue, Made in the USA by Bennett Pump Company. NOTE: Does not include drum.
