Type GPD pumps are vertical, centrifugal slurry pumps submerged in sump to work. Wet parts of type GPD pump are made of abrasion-resistant metal.They are designed for delivering abrasive, large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.

which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of the standard pump, so the pump is with both more steady operation and wider application range, but flushing water should be attached to the guide bearing.

Design features

Impeller一Double suction impellers (top and bottom entry) induce low axial bearingloads

Bearing Assembly一The bearings, shaft and housing are generously proportioned to avoid problems associated with the operation of cantilevered shafts in the first.The assembly is grease lubricated and sealed by labyrinths; the upper is grease purged and the lower protected by a special flinger. The upper or drive end bearing

is a parallel roller type whilst the lower bearing is a double taper roller with preset end float. This high performance bearing arrangement and robust shaft eliminates the need for a lower submerged bearing.
