排量是指泵（或馬達）每轉一周，由密封容腔幾何尺寸變化而得的排出（或輸入）液體的體積，常用單位是ml/r（毫升/轉）。排量可以通過調節發生變化的成為變量泵（或變量馬達），排量不能變化的成為定量泵（或定量馬達）。實際流量是指泵（或馬達）工作時出口處（或進口處）的流量。由于泵本身存在內泄漏，其實際流量小于理論流量。由于馬達本身也存在內泄漏，要實現指定轉速，為補償泄漏量，其輸入實際流量必須大于理論流量。容積效率，對液壓泵是指其實際流量與理論流量的比值。對液壓馬達是指其理論流量與實際流量的比值。機械效率，對液壓泵是指其理論轉矩與實際輸入轉矩的比值。對液壓馬達其實際輸出的轉矩為理論轉矩克服摩擦力后的轉矩，因此其機械效率為實際輸出轉矩與理論轉矩的比值。總效率是指泵（或馬達）的輸出功率與輸入功率的比值。總效率等于容積效率與機械效率的乘積。意大利阿托斯ATOS柱塞泵選型
