IS/CIS型泵系根据国际标准ISP2858所规定的性能和尺寸设计的，主要由泵体、泵盖、叶轮、轴密封环、轴套、机械密封及悬架轴承不见等所组成。
IS/CIS型泵的泵体和泵盖部分，是从叶轮背面处剖分的，即通常所说的后开门结构形式。其优点是检修方便，检修时不动泵体、吸入管路、排出管路和电动机，只需拆下加长联轴器的中间联接件，即可退出转子部件进行检修。
泵的壳体（即泵体和泵盖）构成泵的工作室。叶轮、轴和滚动轴承等为泵的转子，悬架轴承部件支承着泵的转子部件，滚动轴承承受泵的径向力和轴相力。
为了平衡泵的轴相力，大多数泵的叶轮前、后均设有密封环，并在叶轮后盖板上设有平衡孔。由于有些泵的轴向力不大，叶轮背面未设密封环和平衡孔。
IS型泵的轴向密封采用填料密封，由填料压盖填料环和填料组成。
CIS型泵的轴向密封采用机械密封，可减少泵的泄露量。
泵的叶轮如有平衡孔，则装软填料的空腔与叶轮吸入口相通，若叶轮入口处液体处于真空状态，则很容易沿着轴套表面进气，故在填料腔内装有填料环，通过轴盖上的小孔，将泵室内压力水引至填料环进行密封。泵的叶轮如没有平衡孔，由于叶轮背面液体压力大于大气压，因而不存在漏气问题，故可不装填料环。为避免轴磨损，在轴通过填料腔的部位装有轴套保护，轴套与轴之间装有O型密封圈，以防沿着配合表面进气或漏水。
泵的传动方式是通过加长弹性联轴器与电动机联结的。泵的旋转方向，从驱动端看，为顺时针方向旋转。 |
