Standard impeller is open type designed to extend pump life. Thick vanes and full back shroud provide outstanding resistance to wear and breakage. Large balance holes and back pump-out vanes reduce axial thrust and stuffing box pressure for increased bearing and seal life.
The entire 3180/3185 line (33 sizes) uses just four power ends
Contamination being the second leading cause of bearing failure requires special attention. Common lip seals were not considered due to their 2,000 hour design life. After wearing out, there will be an open passage way for contamination. For this reason our 3180/85 is provided with labyrinth oil seals as standard.
We picked
Inpro VBXXD isolators since they are durable, corrosion resistant, and the industry standard labyrinth bearing isolator and provide the best operating environment for the bearing.
The unique flow path created by the Vane Particle Ejector directs solids away from the mechanical seal, not at the seal as with other tapered bore designs. And, the amount of solids entering the bore is minimized. Air and vapors are also efficiently removed.
On services with or without solids, air or vapors, Goulds TaperBore™ PLUS is the effective solution for extended seal and pump life and lower maintenance costs.
-
Solids/liquid mixture flows toward mechanical seal/ seal chamber.
-
Turbulent zone. Some solids continue to flow toward shaft. Other solids are forced back out by centrifugal force (generated by back pump-out vanes).
-
Clean liquid continues to move toward mechanical seal faces. Solids, air, vapors flow away from seal.
-
Low pressure zone created by Vane Particle Ejector. Solids, air, vapor liquid mixture exit seal chamber bore.
-
Flow in TaperBore™ PLUS seal chamber assures efficient heat removal (cooling) and lubrication. Seal face heat is dissipated. Seal faces are continuously flushed with clean liquid.
