Building on the outstanding performance of its Z-Class product line, Enerpac has launched the ZU4T-Series electric torque wrench pumps. Similar to the pumps of its class, the ZU4T electric torque wrench pumps are designed to be easy to handle and use, deliver higher oil flow and bypass pressure and cooler running and require 18 per cent less power than comparable pumps. These new pumps are ideal power sources for all hydraulic torque wrenches, come in two maximum operating pressures: 700 and 800 bar; and have a reservoir capacity of 4 to 8 litres, says a Netherlands-based spokesman for the manufacturer

The pumps come with heavy-duty bearings that extend pump life by reducing friction, reducing surface loading and lowering bearing stresses. Their high-strength, moulded composite shroud protects motor and electronics, while providing an ergonomic, non-conductive handle for easy transport, he adds. Dependable "Remote control units with low-voltage pendants provide additional safety for the operator," says the spokesman. Brush design lasts four times longer than current designs and features an "auto-stop" shunt to prevent commutator damage from normal brush wear. The pumps also have an auto-cycle feature, which provides continuous cycle operation of the torque wrench as long as the advance button is pressed. In addition, they can be used with or without auto cycle feature

Innovative The pumps sport an LCD readout that provides pressure display and a number of diagnostic and readout capabilities never-before offered on a portable electric pump. The pump's powerful 1,25 kW universal electric motor provides high power-to-weight ratio and excellent low-voltage operating characteristics

ZU4 series Enerpac has used the latest metallurgical, bearing and seal technologies to produce pumps whose features and benefits far surpass the electric pumps that are available today, the spokesman claims. By reducing the number of moving parts, improving flow ...
