Specification

The SIHImulti pumps are horizontal multistage centrifugal pumps of ring-section design, which meet the technical requirements of ISO 5199 / EN 25199.

Benefits: SIHImulti
• Advanced modular design reduces the number of parts while maximizing interchangeability.

• Optimal selection of impeller diameter and diffuser size installed in a standardized casing ensures that the pump matches the required duty for each application.

• The first stage of each pump size is equipped with a low required NPSH suction impeller.

• Axial thrust is hydraulically balanced by a patented balanced drum system with self-adjusting throttle device.

• Generously sized angular contact ball bearings absorb residual thrust.

• The pump can be built with an axial, vertical, left or right suction and a vertical, left or right discharge in any combination.

• All pump sizes can be provided with one or more " dummy " stages, if required.

Features: SIHImulti
• The pump is driven from the discharge side and the rotor is supported on the side by grease-lubricated anti-friction bearings and on the suction side by self-adjusting sleeve bearing lubricated by the pumped liquid.

• 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.

• Casing components are sealed by O-rings and held together with tie rods.

• The balancing line is returned to the suction casing or to the upstream vessel.

• The mechanical shaft seal is located on the drive side only. Sealing can be ( cooled or uncooled) single acting mechanical seal, packed gland ( cooled or uncooled) or double-acting mechanical seal ( uncooled) .
