This SAE Standard defines the expectations for free-standing, nonintegral, nonpressurized reservoir, flooded inlet type, industrial hydraulic power units used on machine tools and equipment for the automotive industry.These exclude power units used for intermittent and/or noncontinuous duty cycle and pressurized vessels, such as accumulators and air over oil systems.Objectives were set and accomplished to develop a consensus of common features which enhance the power unit performance, manufacturing quality, and maintainability. Some of those features are: a. identification, b. common sizes and construction, c. conductors and connectors, d. pump/motor groups, and e. filters.
