They are used in: - Heating plants - Waterworks and water supply plants - Pressure raising plants - Circulating water and condensate plants - Fire extinguishing plants - Purification plants - Irrigation plants - Boiler feed water plants - Pressurized water producing stations DESCRIPTION AND DESIGN DETAILS Horizontal multistage centrifugal pumps with sectional casing and closed impellers. The manufacturing program covers five sizes, with 2 to maximum 13 stages, according to the size, the speed and the shaft seal. Axial thrust balancing is carried out by balancing the impellers separately. The remaining axial thrusts are taken up by adequately sized antifriction bearings. The impellers, diffusers, as also the wear rings on size 65, are interchangeable between stages. Arrangements combining impeller of differing diameter permit, within the application field, an optimum adaptation of the performance curve of the pump to the required performance characteristics. On the suction side, the mounting feet are arranged on the casing of the first stage. By this means, it is possible to ensure easy adaptation to different installation conditions, even subsequent to initial installation, by pivoting the suction head casing. The driver is arranged on the suction side but discharge side driver or driver on both sides are possible on request. All sizes can be supplied with one or more dummy stages upon request. Maximum casing pressure [ PSI ( bar) ] : Temperature range ( 1) Suction Discharge 14 to 248° F ( -10 to 120 º C) 232 ( 16) 580 ( 40) up to 140 º C 232 ( 16) 551 ( 38) up to 194 º C 188.5 ( 13) 472.7 ( 32.6) ( 1) Limitations due to type of shaft sealing used ATTENTION: The maximum casing pressure is equal to suction pressure plus zero flow head. Flanges: The suction side flange according to DIN 2533 PN16 and the discharge side to DIN 2535 PN40. The flanges can be drilled according to ANSI B16.1 class 250, on request. Flange positions: Suction flange arranged horizontally towards the right hand side ( looking at the shaft end) and discharge flange radially upwards. On request, the suction flange can be arranged on the left and, in the case of pumps with three or more stages, vertically upwards. Bearings: One cylindrical roller bearing according to DIN 5412 and one deep-groove roller bearing to DIN 625, both lubricated by grease. Shaft sealing: Sealing of the shaft can be carried out either by a stuffing box or mechanical seal as required. - Sealing Code 001: Un-cooled stuffing box. Temperature range: 14 to 230° F ( -10 to 110 º C.) - Sealing Code 022: Externally flushed, un-cooled, lengthened stuffing box ( only for sizes 40, 50 and 65) . Temperature range: to 230° F ( -10 to 110 º C.) . - Sealing Code 511: Cooled stuffing box. Temperature range: up to 284° F ( 140 º C) [ refer factory for higher temperatures] - Mechanical Seal Code BK3/ BKS/ BKU: Unbalanced single mechanical seal with rubber bellows, lubricated by pumpage. Temperature range: 14 to 230° F ( -10 to 110 º C.) – [ refer factory for higher temperatures when mechanical seal is required.] SIHI HALBERG HEGA Page 2 Reserved the right to make modifications SIHI Pumps, Inc. / June 2007 Materials of construction Materials of construction( 1) Pos.
