Preasure equals strenth of the work or machine..Flow on the other hand equals speed of the work performend. You will need a good high flow flow meeter to determine if the pump is putting out the recomended flow for the model machine. A small guage capable of measuring 4,000lb preasure will check the relief valves but again all that will tell you is the strength of the machine. Normaly weak or worn pumps show up after the hydraulic fluid warms up. Check the fluid to make sure it is not over heated.
