A new electric tensioner pump from Enerpac is designed to meet the bolt tensioner and hydraulic nut actuation needs of demanding applications, according to the company, which claims its model ZUTP1500 is the only electric tensioner pump on the market to feature a remote-controlled electric valve and universal motor without a hydraulic intensifier.
The resulting pump facilitates hassle-free operation of bolt tensioners and hydraulic nuts in remote locations. With a low-pressure flow rate of 230 in.3/minute (3.77 l/minute) and a full-pressure flow rate of 20 in.3/minute (0.33 l/minute), the new three-piston, two-stage pump design powers bolt tensioners up to two times faster than competitive pumps. The ZUTP1500 includes a durable, lightweight aluminum cage and reservoir with a sheet metal front panel. Enerpac says the ZUTP1500 is compatible with all brands of tensioners that require up to 1500 bar (21,750 psi) of pressure. www.enerpac.com
