IMPELLER |
|
|
|
|
|
Impeller matched to casing for high efficiency
and low NPSH. Fully open, has partial shrouds
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
solids handling ability. |
|
|
|
Impeller is screwed on shaft with rotation to
tighten and threads are sealed by TFE O -
ring Cast-in impeller nut makes removal easy
and minimizes friction losses. This eliminates
projecting impeller nut and exposed threads form
impeller eye. State of the art casting methods
provide smoothest possible surface for highest
efficiency. All impellers are statically and
dynamically balanced. |

STUFFING BOX COVER |
|
|
|
|
|
Encloses back of casing and contains stuffing
box chamber. Cover is fastened to from or
adapter so that a spare back pull-out assembly
can be stocked completely assembled. Cover can
be supplied with jacket for cooling stuffing box
chamber in high temperature services. Jacket can
also be used for heating viscous OR high
freezing point liquids. |
|
|
|
|
|
Packed box has five rings of packing and a
lantern ring. Quench gland with water taps and
an auxiliary ring packing is standard. Gland is
split for easy removal. Tapped openings to
lantern ring permit " IN AND OUT "sealing,
external flushing or lubrication as required. |
|
|
|
|
|
Stuffing box is completely machined for
mechanical seal installation, either originally
or as a field conversion. Inside, Outside,
Unbalanced, Balanced, Single, Double or Tandem
Seals, with any required gland, throat bushing,
throttle bushing and flushing lines furnished to
meet individual sealing problems. Gland
completely confines stationary matting ring
gasket. |

BEARING FRAME |
|
|
|
|
|
Sturdy Cast Iron Construction provides rigid
bearing alignment and shaft support. Oil Seals
on each end and Oil Breather fully protect oil
from contamination while allowing for expansion
or contraction of air caused by ambient
temperature change. To handle liquids above 175˚C,
cast integral cooling chamber is designed for
600 kPa working pressure or 900kPa test
pressure. |

SHAFT SLEEVE |
|
|
|
|
|
Renewable shaft sleeve is positive driven, hook
type, with one end free to expand with
temperature variations. TFE O -
ring prevents leakage under sleeve.
Sleeve permits application of inside balanced
mechanical seals where required. |
