    REXROTH葉片泵本身機械故障。葉輪與泵軸緊固螺母松脫或泵軸變形彎曲，造成葉輪多移，直接與泵體摩擦，或軸承損壞，都有可能降低水泵轉速。

    REXROTH葉片泵電動機因繞組燒毀，而失磁，維修中繞組匝數、線徑、接線方法改變，或維修中故障未*排除因素也會使水泵轉速改變。

    REXROTH葉片泵依靠旋轉葉輪對液體的作用把原動機的機械能傳遞給液體。由于離心泵的作用液體從葉輪進口流向出口的過程中，其速度能和壓力能都得到增加，被葉輪排出的液體經過壓出室，大部分速度能轉換成壓力能，然后沿排出管路輸送出去。

    REXROTH葉片泵主要用于由于顆粒太大以至于一般渣漿泵不能輸送的強磨蝕性物料的連續輸送。適用于挖泥、吸砂礫、疏浚河道、采礦及金屬冶煉爆渣輸送等。

上海維特銳在德國與REXROTH合作，可長期穩定供應力士樂葉片泵，力士樂電磁閥，REXROTH導軌，力士樂柱塞泵等產品
