Milestone
CASTING
Chemical Process pump having top centerline discharge,
self-venting casting, arranged for back pull-out. Fully confined gasket.
Foot support under casing for maximum
resistance to misalignment and distortion from pipe loads. ANSI-B-16.5
(Class 150) flanges standard, ANSI-B-16.5 (Class 300) optional for
working pressure to 2550 kPa with 3 mm
corrosion allowance. For Maximum Corrosion-erosion resistance casing is
supplied without tapped openings but gauge and drain plug openings are
provided when specified.
IMPELLER
Pump Impeller matched to casting for high efficiency and low NPSH. Fully
open, has partial shrounds for maximum vane support without high thrust
inherent in closed impellers. Stuffing box pressure reduced and entrance
of solids prevented by back pump-out
vanes. Large smoothly contoured flow passages combine best slurry and
solid handling ability. Impeller is locked on shaft with impeller
lock-nut and are sealed by Teflon (PTFE)
gasket. State of the art casting methods provide smoothest possible
surfaces for highest efficiency. All impellers are statically balanced.
SHAFT
Pump having a single piece shaft is designed for 0.05 mm maximum
diflection at stuffing box face. all critical surfaces ground to less
than 0.8 micron.
