Power Team Pumps have been continually up-graded for over 40 years; some of the originals are still in service! To meet market needs, PT Hydraulics and Power Team have modified the standard Torque Wrench Pumps, both Air and Electric powered. These new pumps still retain the famous 55 Series Pump but have a new valve to compliment the everlasting pump. The new valve is a single solenoid cartridge style 4 Position, 2 Way valve with an adjustable “B” port relief valve. The new pumps are set for single tool operation as standard however can be fitted with a manifold for 4-Tool operation.
