This product is applicable for feeding such media as water or liquid similar to water at the temperature from -10o C to 80oCWater inlet and outlet are all installed in pump body. Just hoist the pump cover when overhaul, greatly facilitating maintenance.Primary-stage double-suction and secondary-stage single-suction of impeller adopted, greatly improving anti-cavit-ation performance of pump and decreasing axial dimensi on of pump.At rotary speed of 1480 rpm, avoiding vibration caused by high rotary speed.In parison with single-stage pump, the products have same performance and smaller impeller diameter and stable operation.The pumping chamber adopts double-volute design, redu-cing radial force.Applying rolling bearing and lubrication with grease or thin oil and facilitating the maintenance of bearing. Designing in virtue of international advanced hydromech-anics software, modeling by using 3DM software, and ch-ecking the strength with finite element software, ensuring high efficient, stable and reliable operation of pump. Fully mechanical seal ensures no leakage within 8000 h, and packing seal is customizable.The pump turns clockwise, and anticlockwise turning is customizable.This product has applied for national patent (pate nt num-ber: ZL200520046059.0)SLOW 250 - 610 22 Two impellersNominal diameter of impellerOutlet diameter of pumpDouble-stage and double-suction centrifugal pumpShanghai LianchengPartMaterialPartMaterialCast ironHT250Carbon steel40CrPump bodyMagnesium ironQT400-18ShaftStainless steel2Cr13Cast steelZG230-450Cast steelHT250Cast steelHT200Pump coverMagnesium ironQT400-18Stainless steel2Cr13Seal ringCast steelZG230-450Magnesium ironQT400-18Cast ironHT250Magnesium ironQT400-18ImpellerStainless steel1Cr18Ni9TiCast steelZG230-450 denotes general supply, to be supplied as request.clockwise normalWater inlet Clockwise rotation of motorWater outletABC Water outletThe pump can also be manufactured as per A, B and Cturning directions, which shall be specified in contract.Clockwise rotation of motor Water inletABCWater outletWater inletAnticlockwise turningAnticlockwise turningof motorof motorWater inletWater outlet16 1718 19SLOW150-570 2 SLOW200-530 2Structural diagram 1 (for SLOW150-570 2 and SLOW200-530 2)12Pump3Secondary-456Interstage7Shaft89Primary-10BalancingPump casingstageSeal ringShaftSeal ringstagecoverimpellercoversleeve Aimpellerwater pipe11Water-sealed12Mechanical13Gland of14Bearing15Bearing16Bearing17Shaft18Releasing19Clutchpipesealmechanicalbodysleeve Bcoverseal。
