故障率低：结构简单合理，关键部分采用品质配套，整机工作时间大大提高。
维修方便：更换密封、轴承、简易方便。
占地更省：出口可向左、向右、向上三个方向，便管道布置安装，节省空间。
-产品概述：
吸收了上屏蔽泵设计及制造的技术,将电机的屏蔽技术应用于流体输送领域,为适应国内市场需求而推出的系列化新产品。基本符合标准IS02858及标准JB/T6878.2-93的规定。具有设计规范,通用化程度高,结构合理,性能稳定,运转低噪音,无振动等显著特点,是替代常规卧式离心泵,立式管道泵的理想产品。全系列共67个品种,184个规格,其性能范围:流量6.3～1080m3/h,扬程12.5～125m,配用电机功率0.37～160kW,转速1450r/min和2900r/min。
产品特点：
①泵结构紧凑,机泵一体化,体积小。其立式结构具有安装占地面积小,运行平稳,安装无需调整。
②泵进出口设计成规格相同法兰,且位于同一中心线上,可象阀门一样直接安装在管路上,且中心低,便于管道布置,安装特别方便。
③泵与电机同轴,轴向尺寸短,使泵运行更加平稳,噪音低。
④取消传统轴封方式,避免了输送介质的外泄,因此具有无泄漏的显著特点。
⑤用滑动轴承替代常规电机滚动轴承,使泵具有运行特别平稳,振动噪音极低。
⑥安装检修方便,无需拆动管路系统,只要拆下连接体螺母即可抽出全部转子部件进行检查和维修。
⑦可根据使用要求即流量和扬程的需要进行泵的串、并联运行方式。
主要用途：
①普通型供输送清水及物理化学性质类似于清水的其他液体之用。介质使用温度不超过80℃,适用于工业和城市给排水,高层建筑增压送水、园林喷灌、消防增压、远距离输送、暖通制冷循环、浴室等冷暖水循环增压及设备配套。特别适用对振动、噪音要求较高的场合,如地下泵房、空调制冷系统等。
②热水型主要供输送温度不超过160℃不含固体颗粒的软水之用,适用于能源、冶金、化工、纺织、造纸以及宾馆、饭店、浴室、锅炉热水增压循环输送及城市采暖系统循环等场合。
③防腐型供输送不含固体颗粒,具有腐蚀性,粘度类似于水的液体,适用于石油、化工、冶金、电力、造纸、食品、制药和合成纤维等部门。
