Inline Flow Meter Test Kits (Reverse Flow Capable)


To test a hydraulic pump for leakage, you must consider three things: convenience, safety, and accuracy. This portable test kit will give you the same result as testing your pump on a state-of-the-art test bench at a fraction of the cost. Comes complete with adjustable load cell, glycerine-filled pressure gauge, and inline flow meter; ready to load-test your hydraulic pumps, motors, and other hydraulic components safely and accurately.
