PBG40-100屏蔽无声泵是由水泵和屏蔽电动机构成一个密封整体，整体采用静密封设计。屏蔽泵可以广泛使用在采暖、卫生用水、冷冻水系统中无腐蚀的冷水和热水的输送，它是宾馆、医院、工厂、高档住宅等热力交换站、管路集中供暖的理想输送设备。其较之于普通水泵有泵、机一体化结构紧凑，体积小、外形美观、运行平稳、安装方便、无噪音、零泄漏、等特点，X大限度的满足用户日益增长的对工作环境的稳定性与环保要求。
| PBG40-100屏蔽无声泵为立式水泵，电泵有水泵和屏蔽电动机（以下简称电机）两部分组成。水泵部分主要零部件叶轮、泵体、密封环，电机部分主要零部件有定子、转子、屏蔽套、轴承座、轴承、推力盘、冷却管、放气阀等零部件组成。 电机选用HX绝缘绕组。转子由不锈钢轴和铸铝转子组成。为了防止输送液体进入定子和腐蚀转子，在定子内径及转子表面分别用不锈钢屏蔽套密封。 密封性：泵体法兰与电机法兰连接处，机座与轴承座及定子屏蔽连接处均有耐热O型密封圈密封。 泵叶轮悬臂安装在电机转轴上，由键和螺母予以固紧。 润滑与冷却：采用外循环。当泵工作时，由电泵出口处引出少量液体经过冷却管、后轴承与轴颈间隙、定、转子间隙、前轴承与轴颈间隙、叶轮后口环组成一循环回路（单X）、X后一X叶轮进口环组成一循环回路（多X）。 |

1、屏蔽泵的X点：
①与有密封泵相比，省去了维修和更换密封的麻烦，也省去了联轴器零件数量少（只有机械密封的30%左右），可靠性高。无滚动轴承和电动机的风扇不需要加润滑油，且运转平稳、噪音低（一般为60~65dB（A））。可配置轴承磨损检测器，检测轴承的磨损情况。
②结构紧凑，占用空间小，对底座和基础的要求低，没有联轴器的对中问题，安装容易且费用低。日常维修工作量小，维修费用低。
③能在真空系统或“真空”与“正压”交替运行的情况下正常运转而无泄漏。可以再高真空度情况下直接从真空槽中把物料送至其他容器中。使用范围广，对于高温、高压、极低温等各种工况均能满足要求。
2、屏蔽泵的缺点
①由于采用滑动轴承，用被输送的介质润滑，故对润滑性差的介质就不宜采用屏蔽泵输送。一般适合于屏蔽泵输送。一般适合于屏蔽泵的介质粘度范围为0.1~20cp。
②屏蔽泵的效率通常低于有密封泵的离心泵，但在中、小功率的情况下，与双端面密封泵相比，后者由于增加了冷却和冲洗系统的功率消耗，故总功率相差不大。
③离心泵运行时，要求流量要高于X小连续流量。对屏蔽泵这点尤其重要，因为在小流量情况下，泵效率较低且会导致发热，使流体蒸发而造成泵干转，引起滑动轴承的损坏。
