The VB pump is
designed for use in slurry and acidic applications with the
discharge at the top of the pump.

A. Standard
Cast Iron or Steel Fabricated Motor available.
B. HRC coupling allows for impeller adjustment
C. Top adjustment for impeller wear to maintain hydraulic
performance and efficiency.
D. Conservatively sized floating radial bearing, lightly
loaded due to the “Twin Volute” casing and
high-capacity, matched- pair angular contact thrust bearings.
E. Rugged cantilever shaft. No submerged bearings or
stuffing box.
F. Renewable shaft sleeve protects shaft from wear.
G. Semi-open or enclosed impeller matched to casing for the
best hydraulic efficiency.
H. Bottom suction inlet with external agitator to draw in
the maximum solids.
I. The double discharge Twin Volute construction provides
balanced radial loads.

THE ADVANTAGES OF
BOTTOM SUCTION CONFIGURATION
-
The design allows for fully, partial
and non-submerged conditions.
-
The twin volute casing is designed to
balance hydraulic forces exerted on the pump shaft during
operation. This promotes extended bearing and mechanical seal
life.
-
The agitator at the inlet to the
impeller breaks down and re-suspends compacted solids thereby,
assisting the pump to transfer a higher percentage of
solids.
-
All the pumps can be supplied
certified to flameproof specification.
-
Submergence depth up to 20m
H20.
-
All pumps have double mechanical seals
for improved sealing of the motor.
-
Dry run
