屏蔽泵是一种无密封泵。
泵和驱动电机都被密封在一个被泵送介质充满的压力容器内，此压力容器只有静密封，并由一个电线组来提供旋转磁场并驱动转子。这种结构取消了传统离心泵具有的旋转轴密封装置，故能做到完全无泄漏。此外，屏蔽泵的制造并不复杂，其液力端可以按照离心泵通常采用的结构型式和有关的标准规范来设计、制造。
屏蔽泵的特点
1、电机与泵一体化结构，全部采用静密封，使电泵完全无泄漏；
2、全封闭、无泄漏结构可输送有毒有害液体物质；
3、采用屏蔽式水冷电机和取消了冷却风扇使该泵低噪声静音运行，适用于对环境噪声要求高的场合；
4、采用输送介质润滑的石墨滑动轴承，使运行噪声更低且无需人工加油，降低了维护成本；近几年轴承材质又增加有碳化硅SIC，超硬等，使用寿命优于石墨轴承。

在制作无油自润滑轴承时可能需要用到胶水，因为河南大山有色金属石墨和铜块都是固体，固体与固体之间的紧密配合肯定是有间隙的，对与做精密润滑石墨轴承来说的话0.1毫米的间隙已经很大了，几乎用肉眼都能看的出缝隙来，那么如果解决这一问题呢？协力石墨根据多年的经验判断可以用密封胶或者润滑胶，不但可以很好粘结石墨柱与铜套孔，还可以填满石墨颗粒铜孔位之间的间隙，当然间隙不能过大，一般控制在0.15左右为最好，间隙过大胶水的分量会增加，协力石墨的润滑石墨柱，石墨颗粒采用的是高密度的石墨车加工而成，直径非常标准统一，不会出现这次买的和下次买的直径不一样看强度要求,如果强度要求不高用ab胶；如果强度要求高，可以使用某种加温固化的胶。
如果是机械行业铜套镶嵌石墨，两者需要按照过盈配合加工。加热铜套使之孔径胀大，之后放入石墨棒，冷却河南大山有色金属铜套后即卡紧。
