Hydraulic Torque Wrenches require a pump to operate, but this isn’t a one size fits all proposition! We offer several options for both sale and rental to best fit your requirements. Electric powered units are most common. Our standard, general duty units feature a three stage pump for fast operation and low current draw with a standard heat exchanger for cool operation for continuous use. Additionally, we have units with an efficient “auto-cycle” feature, and compact units when portability is key. If electrical power is not available, or if job conditions and classifications require an explosion proof unit, air powered units are available, all from Michigan stock.
