Building on the outstanding performance of the Z-Class product line, Enerpac is proud to introduce the ZU4 Electric Torque Wrench Pumps. Like other pumps in the Z-Class family, the ZU4 Electric Torque Wrench Pumps are designed to deliver ease of handling and use, higher oil flow and bypass pressure, cooler running and require 18% less current draw than comparable pumps. These pumps are ideal power sources for all torque wrenches. The pumps are offered in two maximum operating pressures: 10,000 & 11,600 psi; and the reservoir capacity is 1.0 – 2.0 gallons.

Tough – Heavy-duty bearings extend pump life by reducing friction, reducing surface loading and lowering bearing stresses. The pump's high-strength, molded composite shroud protects motor and electronics, while providing an ergonomic, non-conductive handle for easy transport. Dependable – Remote control units with low-voltage pendants provide additional safety for the operator. Brush design lasts 4-times longer than current designs and features an "auto-stop" shunt to prevent commutator damage from normal brush wear. Auto cycle feature provides continuous cycle operation of the torque wrench as long as the advance button is pressed. (Pumps can be used with or without auto cycle feature.) Innovative – The LCD readout provides pressure display and a number of diagnostic and readout capabilities never before offered on a portable electric pump. The pump's powerful 1.7 hp universal electric motor provides high power-to-weight ratio and excellent low-voltage operating characteristics.
