WB3
WB3系列四氟波纹管机械密封，为大头泵/过滤机泵专用款，采用分体式动静环、全封闭内置弹簧结构，杜绝弹簧腐蚀，耐强酸碱、氢氟酸及电镀结晶介质，是化工电镀过滤泵专用密封件。
WB3 series PTFE bellows mechanical seal, specially designed for big-head filter pumps. Adopts split ring and fully enclosed internal spring structure to avoid spring corrosion. Excellent resistance to strong acid, alkali, hydrofluoric acid and electroplating crystallized media.
产品介绍 / Description
本款为大头泵/过滤机泵专用WB3，适配国宝、塑宝、三川宏等WB系列电镀耐腐蚀大头泵；结构为白色四氟波纹管总成+碳化硅动环总成。市场存在一款全金属无波纹管同名WB3（普通化工离心泵用），两款型号同名、结构尺寸完全不通用，采购安装请勿混淆。
This WB3 is specially for big-head filter pumps, compatible with KuoBao, Sumpod, Sanchuanhong WB series anti-corrosion electroplating pumps. Structured with PTFE bellows assembly and silicon carbide rotary assembly. There is another all-metal non-bellows WB3 for chemical centrifugal pumps in the market. They share the same model name but are completely non-interchangeable in structure and size.
