Back Pull-Out
Allows unit to be removed without disturbing suction and discharge piping. Simple and fast installation of spare power end.
Centerline Supported
For high temperature services. Eliminates misalignment of pump and motor shafts due to thermal expansion of casing.
Condition Monitoring Sites
Allow easy and consistent monitoring of temperature and vibration for preventive maintenance.
Enclosed Impeller
High efficiency design. Large balance holes and back pump-out vanes reduce axial thrust and stuffing box pressure.
Heavy Duty Shaft/Bearings
Shaft designed for minimum deflection for long seal life and bearing life. Bearings sized for optimum life under tough conditions.
Labyrinth Seals
Inpro VBXXD labyrinth isolators are standard. Prevent premature bearing failure caused by lubricant contamination or loss of oil.
Maximum Interchangeability
The 3181/3186 utilizes the same power ends as the Goulds Models 3180/3185 for reduced spare parts inventory requirements.
Maximum Stuffing Box/Seal Chamber Accessibility
Allows easy maintenance of packing or mechanical seal.
TaperboreTMSeal Chamber
Enlarged, tapered bore for increased life of mechanical seals through improved lubrication and cooling. Self-venting and draining.
