VICKERS雙聯葉片泵是由兩個單級葉片泵裝在一個泵體內在油路上并聯組成。兩個葉片泵的轉子由同一傳動軸帶動旋轉,有各自獨立的出油口,兩個泵可以是相等流量的,也可以是不等流量的。雙聯葉片泵常用于有快速進給和工作進給要求的機械加工的機床中,這時雙聯泵由一小流量和一大流量泵組成。當快速進給時,兩個泵同時供油（此時壓力較低）,當工作進給時,由小流量泵供油（此時壓力較高）,同時在油路系統上使大流量泵卸荷,這與采用一個高壓大流量的泵相比,可以節省能源,減少油液發熱。這種雙聯葉片泵也常用于機床液壓系統中需要兩個互不影響的獨立油路中。
列VICKERS子母葉片泵特點  威格士葉片泵
1、子母葉片的結構設計，減少了葉片對定子的沖擊，在較高的工作壓力和高轉速下，性能更穩定，壽命更長。
 2、子母葉片結構本身具有低噪音的特性。12葉片的設計、流量脈動很小，噪音更低。  威格士雙聯葉片泵、VICKERS雙聯葉片泵、威格士電磁閥
3、多排量的選擇。以及泵芯的插裝式結構，使用戶使用更靈活，維修更方便。雙聯葉片泵　單作用：葉片是鑲嵌在槽里的，可以自由滑動，當旋轉產生時，葉片在離心作用下甩到泵殼上，葉片泵是容積泵，相鄰的兩個葉片運動到下邊時與泵殼和轉子封閉的容積zui小，在上邊時zui大，當轉子順時針轉動時，相鄰兩葉片經歷從zui下邊到zui上邊的過程就是容積增大過程，所以吸油（從第四象限到第二象限）；從zui上到zui下是容積減小過程，所以壓油（從第二到第四象限）。 雙作用：當電機帶動轉子沿轉動時，葉片在離心力和葉片底部壓力油的雙重作用下向外伸出，其頂部緊貼在定子內表面上。處于四段同心圓弧上的四個葉片分別與轉子外表面、定子內表面及兩個配流盤組成四個密封工作油腔。這些油腔隨著轉子的轉動，密封工作油腔產生由小到大或由大到小的變化，可以通過配流盤的吸油窗口（與吸油口相連）或排油窗口（與排油口相連）將油液吸入或壓出。 　在轉子每轉過程中，每個工作油腔完成兩次吸油和壓油，所以稱為雙作用式葉片泵，由于高低壓腔相互對稱對稱，軸受力平衡，為卸荷式。
