【中国阀门网】水力专家Enerpac最近研发出一系列节能液压泵，它的活动零件较少，产生的摩擦力也更小，主要为预应加力，后加拉力以及重量级水力作业提供更多力量及可靠性。


Enerpac介绍，EnerpacZU4级1.25kw 700bar电力泵有着很好的流量动力设计，当需要时，它就能够实现更长时间的作业，在更冷的环境中运行以及更轻易的维护。

据公司介绍，ZU4T系列的电动泵，重量在32-36kg之间，使用p1.25kW的通用式电动机，可以提供很高的重力/电力比以及极好的低压运行特性。此电动机结合了一种新的泵要素设计，可以减少油流动紊乱，较少活动零件和摩擦。和可比较的泵相比，它需要的水流牵引力要少18%。

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 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.
