Water Split Case - Brochure

SPP PUMPSSplit Casing PumpsSPP’s Lowest Life-cycle Cost Series of Horizontal Split Casing pumps have been specifically developed to meet the requirements of the 21st century pump user. The best of SPP’s existing, well-proven designs, have been fine tuned with the aid of three-dimensional computational fluiddynamics, to attain the optimum performance minimisingpower consumption and internal re-circulation.Mechanical designs and standard materials of constructionhave been substantially upgraded, in order to offer the enduser unrivalled longevity and the lowest cost of ownership.• Water treatment and supply• Water extraction• Booster pumping• Cooling tower circulation• Process and industrialutility duties• Petrochemical utility duties• Hot Water circulation• Sea water liftTypical Applications:Component Life IncreasedEnergyCostReduced MaintenanceCostsReducedDownTimeReducedLOWEST LIFE-CYCLE COST SERIESSPP’s LLC Series pumps set the standardfor low life cycle cost pumping equipment.LLC Split Casing Portrait_v3 14/6/11 17:21 Page 1Performance and Capacity Flow Rates: Up to 6500 m3/hrHeads: Up to 270 mLiquid Temperature: -10ºC - 120ºC Standard Build (Optional up to 160ºC) Ambient Temperature Range: -10ºC to 45ºCMaximum Solids Content: 1,000 ppm (fines)Maximum Suction Pressures: Mechanical Seal 14 barg,Soft Packed Gland 5 bargStandard Materials of Construction Casing Cast iron*Impeller Stainless steelWear Rings Cast iron / Zinc free bronzeShaft Stainless steel* Non-standard material options available, consult SPP for alloy irons, bronzes or stainless andduplex steelsConfigurations • Horizontal - bareshaft or baseplates mounted with prime mover• Vertical direct mounted*• Vertical open Shaft** Vertically mounted pumps incorporate a drinking water approved, product lubricated bottom bearing as standard.Impeller positively locked and key to pump shaft.
