Maintains rotating assembly axial location and unloads pump hydraulic thrust. > Eliminates vapor lockingand ensures lubrication and cooling of the mechanical seal. > For high temperature operation and for maximum resistance to corrosion and erosion. Prevents accumulation of debris on the internal pump components. > Reduces rotor vibration andimproves stability on multistage pumps. Continuous pressure lubricated bearings ensure long life and reduced maintenance. > Limits interstage recirculationand dramatically reduces friction. Teflon > effectivelyresists thermal distortion and has excellent...

Armstrong Series 4700, designed for temperatures ranging from 5F to250аF(-15C to 120аC), are well suited for boiler feed applications, condensate recovery and air conditioning systems. Easy to incorporate into industrial environmental engineering equipment,our Vertical MultiStage pumps combine the advantages of compact design, quiet operation and ease of maintenance. > From basic water supply to the most specific pressure boosting and fire line pressure maintenance applications, Armstrong Series 4700 Vertical MultiStage pumps satisfy all water distribution requirements. The wide pressure range...
