Long shaft submerged slurry pump
CL long shaft submerged pump is deriving product of CLWⅡ series, it was designed to meet the special requirements of long shaft submerged pump, like no stale clean water(for pump lubricating) at site, or only needs to pump clean water, and the cost problem.There are various materials available for our long shaft submerged pump, including cast iron, stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
■Flow rate: Q=140～9400 （m³/h）
■Total head: H=12～68 (m)
■S.g.: γ ≤1.15
■Pump diameter: 150～1000mm
■Adopted advanced structure and hydraulic models to enable long life operation of high efficiency and stability.
■Compact structure takes smaller space,saving the construction cost.
■Standardized sectional length of pump shaft to meet different submerged depths, which is up to 25 m.
■Grease lubricated bearings can work properly even if the bearings are slightly soaked.
■Secondary impeller design to reduce the pressure, and there are holes on the impeller to balance the fluid pressure to ensure the sealing performance.
■Sectional combination structure enables the sectional maintenance to save the cost of operation.
■Guide vane type submerged pump,impeller is immersed in the fluid,the guide vanes in the middle section pushing the fluid all the way up along the main shaft.
■Impellers can multiply work in series,and the shafts and water guide pipes can be connected to enlarge the usage scale of pump.
■Shafts are connected by a special method with high precision to ensure the alignment and smooth operation of pump.
■The pump shafts are supported by roller bearings;the fluid is separated with shafts by the guard plates.
■Vertical installation with horizontal pump outlet; The rotary part is driven by the motor through the couplings.
