MG12机械密封系列属单端面、单弹簧、非平衡橡胶波纹管机械密封,可以任意旋向。
MG12机械密封系列是常用的密封,结构参照国外的同类产品设计,它设计精巧、外形美观,具有多种功能,通过动环更换成各种材料。可在含有颗粒的废水、污水中应用。MG12机械密封也可用于串联式或背对背式的双端面密封。
使用范围:
适用于各种离心泵|管道离心泵,排污泵,化工泵|耐腐蚀泵,不锈钢水泵,液下泵,自吸泵。
静环(陶瓷/碳化硅/碳化钨)
动环(车制石墨/碳化硅/碳化钨)
辅助密封(丁腈胶/三元乙丙胶/氟胶)
弹簧及其它金属件(不锈钢)
MG12 机械密封系列标准配G60静环(DIN24960),另外还可提供G4,G6,G9静环
