1 HPDM Volute Casing PumpsAxially SplitSulzer Pumps - working with youfrom design to operationSulzer Pumps combines more than 135years of experience in pump develop-ment and manufacturing with a deepcommitment to fully understanding theneeds of our detailed process and applicationknowledge has allowed us to developinnovative pumping solutions for ourfocus segments including tailor madesystems if required. Our active research& development supports this customeroriented Pumps has a long history ofproviding innovative pumping solutionsto business partners in the followingindustries: Oil & Gas Hydrocarbon Processing Pulp & Paper Power Generation Food, Metals and Fertilizers Water and WastewaterWater and WastewaterAround the world, reserves of puredrinking water are being depleted.

2 Theneed for water conservation is growing,and better ways are being found toprocess industrial wastewater and treatsewage in urban areas.

Weoffer pumping solutions for modernreverse osmosis plants, where seawateris transformed into water fit for humanconsumption. Our Pumps are deliveringvast quantities of fresh water over longdistances to people in some of theworld s most populous Volute Casing Pumps , Axially SplitApplicationFor the transport of fresh water andseawater as well as other clean orslightly contaminated rangeThe overall performance range pro-vides for discharge rates of 1'000 to20'000 m3/h and delivery heads of130 to 680 rangeThe Pumps are designed for a testpressure of 150 bar ( ) and100 bar ( ).

3 Temperature rangeThe maximum allowable fluid temper-ature range for water is 0 to 50 fields ofapplication Pumping stations for pipelines trans-porting fresh water or seawater WaterworksPump Design is a single stage, hori-zontally Split , double Volute , and dou-ble suction pump. It is designed ac-cording to Sulzer the nuts to the Casing Split flangeare removed, the upper half of thecasing can be lifted off. The rotorconsisting of impeller, shaft and shaftseals can be checked and lifted outwithout disturbing the piping connec-tions or pump alignment. The pumpcan be driven from both Design is selected for higherhead applications. A single suctionimpeller is installed on each side ofthe double suction impeller. The flowis guided in the diffusers from the firststage to the second two suction branches are integralto the lower half of the pump casingand are connected by means ofbreeches pipe.

4 The suction branchescan be arranged either horizontally(inline with the discharge) or Casing is horizontally Split and ofthe double Volute type minimizing theradial forces acting on the shaft. Thesuction and discharge branches areinline, horizontal, located on oppositeside, cast integrally with the lowerhalf. Both Casing halves are boltedtogether and sealed with a double suction impeller is of theclosed type. It is keyed to the shaftand located Axially on the shaft bymeans of sleeves and shaft double suction impeller is hy-draulically balanced, has low NPSH performance and low disc friction loss-es, resulting in high ringsBoth, the impeller and the Casing haverenewable wear large diameter pump shaft forhigh stiffness combined with a doublevolute Casing results in small shaftdeflection and ensures good perfor-mance of bearings and shaft seal sleevesReplaceable shaft sleeves are provid-ed on each side of the impeller in thearea of inlet and shaft of PumpDouble-actingtilting pad thrust bearingSuction branchNDE journal bearingShaft sealBoth, mechanical seals and packingrings can be supplied.

5 The mechani-cal seal is generally of the cartridgetype. It can be removed and replacedas a single unit. The fluid properties,the shaft peripheral speed and thesuction pressure limit the use of pack-ing and lubricationForced feed or self-lubricated hydro-dynamic bearings are available.
