Axial Split Case Double Suction Centrifugal Pump

Product Description Axial Split Case Double Suction Centrifugal Pump   Construction  200WN to 500WN dredge pumps are of single casing, single stage cantilevered horizontal centrifugal  pumps. Two types of coupling with gear box: frame and pump box.    600WN to 1000WN dredge pumps are of double casings, single stage cantilevered centrifugal pumps.  These pumps are equipped with frame and lubrication is force thin oil. The design of double casing the  pump working till the volute liner almost worn down and guarantee no leakage when volute liner is worn down.    Easy Uninstallation & Convenient Maintenance  WN dredge pump is of front uninstallation construction to make uninstall easily and convenient maintenance. And special tools are equipped for uninstalling the parts.  Standard four-head trapezoid thread connection between impeller and shaft can transfer powerful torsion and be convenient to uninstall. Impeller uninstall ring at shaft sleeve side also make the impeller  uninstallation much easier.    Good Performance Good NPSH can not only guarantee suction but also make deep dredge and high allowable suction  density. Minimum NPSH: 4m.  With wide impeller passage, pump can continuously pump gravel or high plastic clay without clogging.  Max allow particle size: 350mm.  Performance curves descend obviously to make pumps adopt pipeline distance changes.  By changing the impeller diameter or impeller rotating speed, it can easily change the discharge with  the same flow rate.    Material  Material of wet parts is high wear resistant high chrome alloy.    Considering the maintenance, wear resistant parts are nearly of the same wear life to reduce maintenance & interchange costs.  Low Hydraulic loss, High efficiency, Energy Saving  Efficiency of WN is 2 or 3 percentage higher than other common pumps.    Reliable Shaft Seal, No leakage  Shaft Seal types of 200WN to 500WN: Mechanical seal, packing, or combination of mechanical and packing  600WN to 1000WN uses helical casing L rubber seal which is made of 3 pieces of L seal ring and one  special thread shaft sleeve.    Turning  700WN to 1000WN can be equipped with turning to change rotating directions.       Features   *Adopted high chrome impeller, suction cover and agitator as standard supplies. *High efficiency and quality motor in a rigid structure ensures long durability. * Adopted top quality mechanical seal. *Easy operation, handling and maintenance.     Applications   *Dredging sand slurry gravel soil sludge mud paste mire slime slush at river, river mouth and sea floor *Transferring sand, slurry, gravel, soil, sludge at mine, civil works, construction sites, ready mixed concrete factory, Rock Wool Industrial ,Copper Mine Industrail, Petroleum Industrail, recruiting construction materials factory and power plant etc. *Removal sediment from sumps or basins.     FAQ *Can you supply pump qualified with ANSI and ASME standard?
