Vertical submerged slurry pump
ZLJ vertical submerged slurry pump is a China patent product of Zigong Pump & Valve, which adopts a stirring impeller at the pump inlet to solve the problem of quick sedimentation of medium. ZLJ series is cantilever and double-bracket structure, which increases the reliability and stability during operation. More than 10 kinds of materials are available for different applications. It is suitable to pump fluids with suspended particles, and is widely used in industries of power plant, chemical, petrochemical, mines and cement..There are various materials available for our vertical submerged slurry pump, including cast iron, stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
