Enerpac has developed a new gravity-operated hydraulic pump

Hydraulic specialist Enerpac recently developed a range of energy-saving hydraulic pumps that have fewer moving parts and generate less friction and provide more power and reliability primarily for preload, post-load and heavy-duty hydraulics. According to Enerpac, the EnerpacZU4 class 1.25kW 700bar electric pump has a very good flow-power design that allows longer operating hours, cooler conditions and easier maintenance when needed. According to the company, the ZU4T series electric pump, with a weight of 32-36kg, uses a common motor of p1.25kW and can provide high gravity / electric ratio and excellent low-voltage operating characteristics. This motor incorporates a new pump element design that reduces oil flow turbulence, less moving parts and friction. It requires 18% less water flow traction than a comparable pump. ydraulic 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 occurred arises, Enerpac says. The ZU4T Series electric pumps, which weigh between 32-36 kg, 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. 18% less current draw than comparable pumps.
