轉(zhuǎn)子泵與螺桿泵的配件壽命比較：
轉(zhuǎn)子泵配件壽命長
由于部件之間沒有摩擦，轉(zhuǎn)子泵的配件使用壽命很長。對(duì)過流部件的磨損主要來自于介質(zhì)中的磨蝕性和腐蝕性成分。
螺桿泵配件壽命低
螺桿和襯套之間的摩擦以及介質(zhì)中顆粒物等同時(shí)影響磨損件的使用壽命。偏心旋轉(zhuǎn)的螺桿產(chǎn)生的應(yīng)力全部被襯套承受，這樣加劇了部件之間的磨損。即使是輸送沒有任何顆粒物的介質(zhì)，泵的襯套也會(huì)逐漸磨損。
轉(zhuǎn)子泵與螺桿泵的備件成本比較：
轉(zhuǎn)子泵的備件成本很低
轉(zhuǎn)子泵的可調(diào)轉(zhuǎn)子與可更換轉(zhuǎn)子使得備件成本降到了*低�？筛鼡Q襯板和機(jī)械密封的成本也非常低，配件成本只占整泵的10%~15%左右。
螺桿泵的備件成本很高
由于螺桿泵廠家之間激烈的價(jià)格戰(zhàn)，使得出售整泵是不賺錢的，現(xiàn)在螺桿泵廠家的利潤主要來自于配件的銷售。一個(gè)*的例子是一套配件的價(jià)格高于整泵的價(jià)格。
