Type ZJ and ZJLR pumps are vertical, centrifugal slurry pumps submerged in sumps to work. They are designed for delivering abrasive, large particle and high slurries. These pumps have no need of any shaft seal and sealing water. they can also be operated normally for insufficient suction duties. Wet parts of Type ZJL pump are made of abrasion-resistant metal. All parts of type ZJLR pump immersed in liquid are lined with rubber our liners. They are suited to transport non-edge angle abrasive slurry.
