产品概述
SPG立式屏蔽离心泵,结构为:单级立式泵,泵叶轮采用离心式,电机为屏蔽式结构,所以可以叫它单级立式屏蔽泵,或者
立式屏蔽离心泵,其泵国标型号均为SPG,只不过是大家叫法不同,泵材质可以选择:精铸铁,不锈钢304 316 316L材质
SPG屏蔽泵是一种电动机和泵体一体化结构的水泵(简单的说就是直联式)机封采用静止密封（而不是旋转的轴密封）
所以能做到完全无泄露。因其电机自身采用水冷却方式所以噪音特别低，加之屏蔽泵铸件,配件等都采用高端产品所以故障率较低
维护成本随之也就低等优点.也增强了对国内市场高品质水泵的需求。
产品广泛应用在石油、化学工业，医药、纺织、核电、军工及城市给排水，消防增压，高层建筑增压送水，园林喷灌，暖通制冷，等冷暖水循环增压。特别是对振动、噪音要求高的场所，如重点工程、泵房、中央空调等等。还可以用来输送压力和温度不产生结晶和凝固的液体，特别是对人体及环境有害的和不安全的液体和贵重液体等,如强腐蚀性，剧毒性，挥发性，放射性等介质。
