分子式：
CAS号：
性质：又称多柱塞泵。是液压装置专用动力泵。由于形状结构复杂，对表面光洁度和加工精度要求高，只用于润滑性能好，清洁无杂物，对金属零部件无腐蚀甚至对精加工表面有良好保护作用的特制液压油介质。专门用来向液压执行机构(如液压缸或液压马达)泵送可变流量的高压油。每一柱塞构成泵的一个单元。柱塞缸轴向布置时，定子滑道为可倾斜的端平面，称为轴向多柱塞泵(anial multiplunger oil pump)。如柱塞缸径向布置，定子内壁的圆柱面为柱塞滑道，而且转子必须偏心地、可调地装在定子内，这种结构称为径向多柱塞泵(radial multiplunger oil pump)。具有节能、高效、自控、准确可靠等优点。
