Product Information SIHImulti MSL, MSM - 1

Modular multistage pumps SIHImulti Type MSL, MSM 133.23301.57.01 E PUMP TECHNOLOGY SIHImulti MSL, MSM 02/2008 Description SIHImulti pumps are horizontal multistage centrifugal pumps of ring-section design, which meet the technical requirements of ISO 5199 / EN 25199. 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 Pumps of the SIHImulti range 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 max. 450 m³/h Head max. 630 m Speed max. 3600 rpm Temperature -10 to +180°C * Pressure Rating max. 63 bar Shaft seal - packed gland - mechanical seal Direction of rotation counter-clockwise, when viewed from discharge side * 200°C as special design for example pump feet are mounted concentric in accordance to ISO 9905 Construction 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 an suction impeller. Axial thrust is hydraulically balanced by a patented balance drum system with a self-adjusting throttling device. Residual thrust is absorbed by a generously-sized angular-contact ball bearing. 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. A mechanical shaft seal is located on the drive side only. It can consist of a packed gland (cooled or uncooled, with external flushing connection), (cooled or uncooled) singleacting mechanical seal or (uncooled) double-acting mechanical seal. The pump rotor is supported on the drive side by greaselubricated anti-friction bearings and on the suction side by a self-adjusting sleeve bearing lubricated by the pumped liquid. The pump is normally driven from the discharge side. As option the pump can be driven from the suction side in which case an antifriction inboard/outboard bearing is provided. The casing components are sealed by O-rings. The pump casings are held together by external tie rods. The pump feet are mounted to the suction and discharge casings in such a manner that the suction casing (for suction casings with radial branch) and discharge casing can be swung to suit the installation conditions. All pump sizes can be provided with one or more dummy stages, if required. Options • Special materials • Monitoring Systems

SIHImulti 3 New Design of Balance Drum System This new, patented design combines a balance drum with a self-adjusting throttling device. The benefits include: • greatly reduced re-circulation flow in the balance line • same balance drum system for different number of stages • high efficiency, lower power consumption • lesser wear rate as this system does not rely on tight, wear-sensitive clearances to control the re-circulation flow Shaft Sealing • uncooled and cooled single-acting mechanical seal • uncooled double acting mechanical seal • uncooled or cooled packed gland more ... for less...
