Hydraulic pumps for heavyweight tasks

Hydraulics specialist Enerpac has developed a range of energy-saving hydraulic pumps with fewer moving parts and less friction to give more power and reliability for pre-stressing, post-tensioning and heavyweight hydraulic tasks.

Enerpac ZU4 class 1.25kw 700 bar electric pumps have good flow dynamics making it possible for them to stay on the job longer, run cooler and be easier to service when the need eventually arises, Enerpac says.

The ZU4T Series electric pumps, which weigh between 32-36kg, employ a p1.25kW universal motor that provides a high power-to-weight ratio and excellent low voltage operating characteristics, the company says. The motor is coupled with a new pump element design that reduces oil flow turbulence, reducing moving parts and friction. It requires 18% less current draw than comparable pumps.
