- Limited Warranty
All Star pumps are covered by a limited warranty on materials and workmanship for one year from the date of manufacture. Star will repair or replace at its option any pump in which Star finds manufacturing defects. In order to get warranty service a pump must be returned to the Star plant freight prepaid with a written explanation of the problem.
Technical Data
Light hydraulic oil is recommended for use with Star pumps. Oils with SUS viscosity of 75 to 150 at 100 degrees Fahrenheit will give satisfactory performance (ISO grade 15, 22, or 32). In an emergency situation when the above oils are not available, use 5 W or 10 W motor oil or automatic transmission fluid.
All exposed surfaces of standard Star pumps are painted with one coat of industrial quality paint. Pumps painted with special colors with two coat finishes, or with prime coat only, and pumps with special plated or polished parts, are also available.
