Features and applications:

This series of pumps is a single-stage, single-suction horizontal centrifugal mud pump. The overflow parts are made of rubber material, which has a long life and is suitable for conveying corrosive slurry. The clearance between the impeller and the sheath and between the impeller and the shield can be adjusted. The shaft seal form has two structures of impeller and packing. When the impeller sealing structure is used, the inlet perfusion height shall not exceed 5m; When packing seal is used, the shaft should be injected higher than the working pressure of 1kg/cm²

Description of model meaning: 2PNJFB

2-- pump outlet diameter (inch); P-- impurity pump; J-- Rubber; F-- corrosion resistance; A-- one improvement; B-- The second improvement.
