威格士VQ系列泵/VICKERS双作用叶片泵 
威格士VQ系列泵是专为中等压力的移动应用。它的10个叶片系统是调整为更高的压力和更高的速度移动要求。V系列泵一样，它具有业界*个叶片内的墨盒设计，提供运行寿命长，优秀的容积效率和优秀的可维护性。设计有一个稳固的架构，是由世界的移动设备制造商广泛采用。积分流量控制阀可用于20VQ框架。此外，重型轴承选项为26VQ，36VQ和46VQ VQH系列泵是更高的压力和较高的VQ系列泵的性能版。新的转子设计，降低了内部泄漏，提高了转子的刚度。VQH泵使用强大的球墨铸铁外壳，并具有相同的信封大小的VQ泵。VQH系列泵是单和通轴驱动泵的3帧大小：25，35，和45；双泵有2520，3520 ，3525， 4520，4525，4535。
威格士叶片泵的工作原理
威格士叶片泵转子旋转时，叶片在离心力和压力油的作用下，尖部紧贴在定子内表面上。这样两个叶片与转子和定子内表面所构成的工作容积，先由小到大吸油后再由大到小排油，叶片旋转一周时，完成两次吸油与排油。
威格士单作用叶片泵的工作原理
威格士泵由转子1、定子2、叶片3、配油盘和端盖等部件所组成。定子的内表面是圆柱形孔。转子和定子之间存在着偏心。叶片在转子的槽内可灵活滑动，在转子转动时的离心力以及通入叶片根部压力油的作用下，叶片顶部贴紧在定子内表面上，于是两相邻叶片、配油盘、定子和转子间便形成了一个个密封的工作腔。当转子按逆时针方向旋转时，图右侧的叶片向外伸出，密封工作腔容积逐渐增大，产生真空，于是通过吸油口6和配油盘5上窗口将油吸入。而在图的左侧。叶片往里缩进，密封腔的容积逐渐缩小，密封腔中的油液经配油盘另一窗口和压油口1被压出而输出到系统中去。这种泵在转子转一转过程中，吸油压油各一次，故称单作用泵。转子受到径向液压不平衡作用力，故又称非平衡式泵，其轴承负载较大。改变定子和转子间的偏心量，便可改变泵的排量，故这种泵都是变量泵。
威格士双作用叶片泵的工作原理
威格士双作用叶片泵的作用原理和单作用叶片泵相似，不同之处只在于定子表面是由两段长半径圆弧、两段短半径圆弧和四段过渡曲线八个部分组成，且定子和转子是同心的。在图示转子顺时针方向旋转的情况下，密封工作腔的容积在左上角和右下角处逐渐增大，为吸油区，在左下角和右上角处逐渐减小，为压油区；吸油区和压油区之间有一段封油区把它们隔开。这种泵的转子每转一转，每个密封工作腔完成吸油和压油动作各两次，所以称为双作用叶片泵。泵的两个吸油区和两个压油区是径向对称的，作用在转子上的液压力径向平衡，所以又称为平衡式叶片泵。
双作用叶片泵的瞬时流量是脉动的，当叶片数为4的倍数时脉动率小。为此，双作用叶片泵的叶片数一般都取12或16。
