Type LBP and LBPR pumps are vertical centrifugal sump slurry pumps submerged in sumps for operation. They are specifically designed for delivering abrasive, large particle, and high-density slurry. These pumps eliminate the need for any shaft seal and sealing water, and can operate normally even during insufficient suction duties.

The LBP series features wet parts made of abrasive-resistant metal, while the LBPR series is lined with rubber, making them ideal for non-edge angle abrasion slurry. The 'L' extension shaft series is available for deep-level applications, featuring an added guide bearing for steady operation.
