High Pressure Pumps Series SIHImulti MSH, 250 m³/h, 1600 m, 180 °C - 1

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. Applications multi Pumps of the SIHI range type MSH meet the specific requirements of many applications, such as: • • • • • • • • • • Waterworks and water supply Boiler feed Pressure boosting Irrigation High pressure cleaning Heating Condensate systems Reverse osmosis Chemical and Process and many more ... Technical Data Flowrate Head Speed Temperature Pressure Rating Shaft seal Direction of rotation max. 250 m³/h max. 1600 m max. 3600 rpm -10 to +180°C max. 160 bar - packed gland - mechanical seal counter-clockwise, when viewed from discharge side 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. Special materials Monitoring systems PUMP TECHNOLOGY SIHImulti MSH 10/2001

Suction Impeller First stage impeller ensures reliable operation with low NPSH conditions. Discharge Nozzle Large diameter provides low flow velocity and quiete operation. Different nominal pressure stages are available. Suction Position Adaptable design allows for either radial or axial suction. Impeller Long hubs provide stable fit to the shaft, even at changing operating temperatures. Modular Design Modular geometry of impellers/diffusers permits optimal hydraulic design matching all duty conditions. Product Lubricated Sleeve Bearing Self-aligning bearing for higher reliability.
