Description
40 300 1000 6000 Q(m3/h)
Horizontal axially split casing, double volute multistage
design. Impellers arranged in opposed groups, O2KS is a
double suction two stage pump for larger capacity. O2KY is
a multistage single suction impeller pump for higher head,
first stage double suction impeller design for low NPSH
required.
Removable wear rings protect the casing and impeller.
The impellers are statically and dynamically balanced. The
pumps comply with the latest API 610 specifications in all
technical details. Special anti-friction bearings on both
sides or sleeve bearings with ring or forced-feed
lubrication (axial bearing as segmental thrust bearing).

Description
The casing is axially split, which permits removal of the
complete rotor without moving either piping or motor.
Pumps generating high heads have double volutes to
reduce radial forces. Replaceable wear rings protect the
casing at the impeller running clearances. Flange drilled
to ISO, DIN, BS or ANSI.
The close double suction impeller gives practically zero
axial forces. Each impeller is statically and dynamically
balanced according to ISO 1940.
Vertical or horizontal, soft packing or mechanical seal,
grease or oil lubrication bearing on request.
