nyt) Design
The extraction pumps of the NPCV
‘series are single-stage centrifu-
gal pumps featuring a central in-
let and a tangential outlet as well as
a vertical shaft, single-stage spiral
ceasing with single flow direction.
‘The pump can be ited with various
types of impellers of various
materials. Apart from the standard
‘open type impeller (NPCVX), closed
impellers (NPCV) or vortex impellers
(NPCWWY are available,
The spiral casing (cscherge
ceasing) can be rotated at staps of
45° to the Intermediate casing
(suction casing.
‘The bearing assembly cor:
prises a clean-water lubricated, low-
maintenance plain bearing at the
bottom end, a sofd coupling and a
fixed bearing in the electric motor at
the drive end; thus exact concentric:
ity is guaranteed.
‘The shaft seal consists of an eas-
ily accessible, maintenance-free
throttle bush.
‘The pump is driven by a three-phase
squirrel cage motor with surface
‘cooling and with a fixed bearing at
the drive end. Construction IM V1,
‘enciosure IP&4 according to IEC
standard, insulation class 8, output
and main dimensions according to
