SIHImulti Pump MSH

SIHImulti Pump MSH 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 pump ensures that the pump closely matches 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 a suction impeller. Axial thrust is balanced by a combination of a balance drum and balance disc. For special applications 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 oil lubricated anti-friction bearings and on the suction side by self-adjusting sleeve bearings, 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 an interstage bleed-off device if required.
