Modular multistage pumps

SIHImulti
Type MSH
Description
multi

SIHI
pumps are horizontal multistage centrifugal pumps
of ring-section design, which meet the technical
requirements of ISO 5199 / EN 25199.
The type MSH is developed for the high pressure range up
to PN 160.
The advanced modular design reduces the number of parts
whilst maximising interchangeability.
Optimal selection of impeller diameter and diffuser size for
each ensures that the pump closely match the required duty
conditions.

Different hydraulic impeller and diffuser sizes can be
installed in a standardised casing, thus enabling the pump
to be designed exactly for the working point required. The
first stage of each pump size is equipped with suction
impeller.
Axial thrust is balanced by a combination of a balance drum
and balance disc. For special application an additional
balance disc lift-off device is available. The balancing line is
returned to the suction casing or in the upstream vessel.
Standard suction casing construction is with axial or radial
inlet nozzles.
The shaft is sealed by packing or mechanical seal. A variety
of designs are available (cooled or uncooled).
The pump rotor is supported on the discharge side by oillubricated anti-friction bearing and on the suction side by a
self-adjusting sleeve bearing lubricated by the pumped
liquid or by oil-lubricated anti-friction bearings.
The casing components are sealed by O-rings. The pump
casings are held together by external tie rods. The pump
feet are bolted to the suction casing such as to facilitate
different nozzle positions for extra piping flexibility.
The pump is driven from the discharge side or from the
suction side. All pump sizes can be provided with one or
more dummy stages or with interstage bleed-off device, if
required.
