Vertical Line-Shaft Turbine Pumps - 1

Vertical Line-Shaft Turbine Pumps SIHIhydrolift VETP PUMP TECHNOLOGY VETP 133.20501.51.01 E 09/2006 TECHNICAL DATA Capacity: max. 7000 m³/h Head: max. 350 m Speed: max. 3600 rpm Casing pressure: PN 40 other on request Shaft sealing: gland packing or Mechanical seal Flange connection: UNI 2333 PN 16 / PN 25 Direction of rotation: anti-clockwise, when looking at the Pump from the drive end APPLICATION Vertical line-shaft turbine pumps of the series SIHIhydrolift VETP used for pumping of clean and slightly contaminated liquids, particularly applicable for applications as - Cooling water - Water supply - Irrigation - Filter Backwash - Pressure Boosting - Storm water - Water lift duties - Industrial processes - Hazardous liquids in addition wherever vertical pumps are deemed most suitable for the application concerned. DESIGN Vertical single or multi-stage line-shaft turbine pumps for wet pit or dry installations with closed, open, semi-open or radial impeller. The column shaft pipes have flanged connections and assembled with line shaft bearings. The line shafts are connected with keyed or threaded couplings. The axial thrust bearing is mounted in the pump headpiece. CONSTRUCTION Casing pressure: Maximal 40 bar (other on request) Please note: The relevant technical regulations and safety rules must be observed. Casing pressure = inlet pressure + delivery head at zero flow Flange location: Suction flange vertical, discharge flange horizontal. Flanges: Flanges correspond to UNI 2333/ PN 16 / PN 25. Flanges drilled according to ANSI 150 can be supplied. Hydraulic: Different impeller types are available for the hydraulic of the pump. Depending on the application closed, open or semiopen impellers are available. Bearing: The bearing of the line shaft is realised with a special sleeve, that is quipped with a rubber-bearing bush and lubricated by the pumped liquid. The axial thrust is balanced with a grease lubricated double row, angular contact bearing or oil lubricated roller bearing. Direction of rotation: Anti-clockwise, when looking at the pump from the drive end. Shaft sealing: The shaft is sealed by gland packing or mechanical seal.
