Series 4600FSeries 4600F - Truly SuperiorThe Series 4600F, drawing onover 100 years of pump designRecirculationexpertise and leadership, is thef External Water SealRecirculation Linesstate of the art in Horizontal SplitCase pumps. It meets or exceedsthe requirements of NFPA andtesting laboratories involved in fireCouplingprotection such as UL, ULC, & FM.fUL Listed close-coupled couplingThe family of pumps capitalize onthe “Tilted Parting” concept tominimize turbulence at the eye ofthe impeller by its straight laminarapproach, thus maximizingefficiency. The family wasdesigned with commonality ofparts, low installation cost, andease of maintenance objectives.The pumps’ compact sizes areideally suited for space savingpackages and retrofit applications.Stuffing Box HousingfSelf contained CombinationBearing & Seal Housingf Permits packing change-outwithout having to be removedDrip ContainmentfFitted with drain connectionCasing Wear Ringf Replaceable Case Wear RingsfLocked to prevent rotation oraxial displacementf Impeller Wear Ring availableas an optionPump Casingf Designed to withstand the highpressure requirement typical infire protection
