simplifies maintenance procedures and reduces inventory requirements
-
smoothly directs the flow from stage to stage more efficiently
-
eliminates radial loads to assure longer bearing life
Wear rings
-
allow restoration of “as built” clearances
-
protect more expensive parts from wear
-
casing rings are standard
-
impeller rings are an option
Involute Balance Drum
-
provides axial thrust balance
-
insures rotor stability
-
prevents bearing failure from excessive thrust loading
-
small clearance minimizes leakage and improves efficiency
-
dual step surface protects against seizing or galling
-
accessible and removable from the discharge side of the pump
Suction and discharge casings
-
provide flexibility for customer piping layout
-
radial and end suction configurations are available for the suction casing
-
discharge casing is dual volute type
-
radial suction casing and discharge casing can have nozzles positioned in 90O increments to allow customer flexibility in plant layout and equipment location.
Bearing housings
-
housings on the radial suction pump are identical on both ends
-
Inpro VBXX-DTM labyrinth seals protect bearings from contamination
-
made of high strength cast ductile iron and finned for additional cooling
-
cooling fan for additional thrust bearing cooling on the 5” and 6” sizes
-
bearing housings are configured to accept bearing temperature detectors and vibration instrumentation
Bearings
- end suction (ES) configuration
-
suction side bearing is product lubricated
-
asymmetric trailing edge rib supports eliminate an additional stage for bearing support
-
support rib trailing edge design provides smoother flow into the impeller
-
discharge side bearing is a heavy duty, oil lubricated anti-friction bearing
- radial suction (RS) configuration
-
same bearing housing and anti-friction arrangement as used on the ES discharge side is used at both ends of the radial suction pump
-
anti-friction bearings are oil lubricated
i-ALERTTM
-
i-ALERTTM condition monitor is standard
-
identifies unacceptable changes in vibration and temperature from an accepted operating baseline
-
provides an early visual alert of a potential problem
