Rightshaftseal is critical The shaftseal is usually the weak part of any pump.The reason for this is that the seal area is the only place where there is access to the pumped liquid from the surrounding environment. The life span and efficiency of a shaft seal is totally dependenton the nature of the pumped liquid,and the pres- sure and temperature to which itis subjected.If a leakage occurs,this is usually a resultof wear of the seal faces,or a resultof extreme operating conditions. The shaftseal solutions offered byGrundfos are designed to withstand excessive wear and to provide long life...
