我喜欢它泵装的瓶子，价格也合理。

I love the pump bottle, and the price makes it a true bargain.

液压系统采用了先进的二通插装阀系统、进口高性能的电子泵技术，实现了主缸压力与流量的双闭环控制；

The press takes use of advanced two-way cartridge valve system and imported electric pump technology which can realize double closed loop control of pressure and flow rate.

和离心泵相比，单螺杆泵不需要装阀门，而流量是稳定的线性流动。

And centrifugal pumps compared with single-screw pump do not need to install the valve, while the linear flow of traffic is stable.
