Parker Model 37X Single and Tandem Oil Hydraulic Heavy Duty Pumps and Motors
Here you have a gear type fixed displacement oil hydraulic pump or motor which has been built to very high standards and a new design. The results is the Model 25X pump and motor having operating characteristics far superior to other pumps and motors of it's type. Close fits and small running tolerances were originally built in to insure peak performance and highest operating efficiency.
Slippage is a factor which has considerable bearing on the performance. As the amount of slippage is reduced, the higher the operating efficiency. Best results develop when a close fit is made between the gears and all surfaces they come in contact with. Allowance of a minimum running clearance is, of course, necessary.
Inspection of all Commercial pumps and motors will disclose gears in matched pairs - all are original equipment, made by Commercial on specially built machines which produce surfaces within limits much closer than is standard practice.
Seldom should you find it necessary to service the Model 37X oil hydraulic pump or motor during its life expectancy, but should a noticeable drop in performance occur it is advisable to make an inspection and replace such parts or components which, due to some unusual condition, may have become worn. Should you find it advisable to replace the gears, insist they be in matched pairs and the product of the original manufacturer. Matched gears are the very vitals of the gear type pump or motor. Expendable parts such as "O" ring shaft seals, pocket seals, sing and double lip oil seals and back-up rings should never be re-used even though inspection may show these items as being serviceable for future use. Such parts for replacement are available at a cost which is insignificant in view of your investment and when you consider they vital function of these items is to prevent leakage. All replacement parts should be given your final inspection to insure that no damage has resulted after final factory inspection was made.
