420 系列工程机械泵是开式回路，轴向柱塞设计，提

供许多种控制器使泵具有和每一种用途相匹配的能力。

泵控制器的效率允许降低了对系统冷却的要求。允许

采用更小巧和并不昂贵的设计，换句话说，保持制冷

量不变，而系统的流量增大，于是改善了性能和用户

的满意度。

经过严格考验的旋转系允许泵的连续工作压力至

280bar (4000 psi)，间歇工作压力至 320 bar (4600

psi)，而且维护成本低。重型轴承和刚性驱动轴使泵的

B10 轴承寿命在额定工程机械工况下达到 3320 小时，

降低使用成本，延长使用寿命。

420 系列泵的特点是带有钢背聚合物轴承的鞍形斜盘，

斜盘的特点是压力润滑通道来减少磨损和进一步支撑

内部载荷。刚性斜盘减小了挠度并且使轴承载荷均匀，

延长了寿命。单控制柱塞减小作用在斜盘上的力，结

果是泵的尺寸减小，允许安装在更紧凑的位置。

420 系列泵的工作噪声很低，安静程度超过了当今对

工作条件的要求。泵的另一个特点 - 双金属配流盘 - 改

善了泵的加注特性，也降低了流体噪声并且延长了泵

的寿命。

安装法兰有 SAE 和 *** 配置，油口有 SAE 和 *** 管

螺纹和法兰品种，提供各种安装方式用在全球的机器

设备上。

侧油口或端油口品种有货，便于布管和把泵安装在设

备需要的空间，有多个泄油口，允许多种安装方位，

降低安装成本。
