Overview:

GD-and D-type pump for delivery of solid particles in water. DF-and Dll-type pump for mine is the carriage of PH 2 to 4 acid mine water. Transmission medium temperature shall not exceed80 ℃.

Flow range: 0 = 100-515m. / H (GD D-type

0 = 27-346m. / H (DF DII type

Head range: H = 66 ~700m(GD D-type

H: 66 ~459m(DF D1 "type

Structure:

This pump is a horizontal, single-suction, multistage segmental centrifugal pump. Intake can be horizontally or vertically upward, the outlet is vertically upward. With eight out wear bar to smoke, and spit out the middle section connected into one.

Pump rotor mounted on the shaft of the impeller, balance disc and other parts, the rotor mounted on the pump by the end of the two roller bearings to support. Bearings with grease lubrication. By the rotor axial thrust balancing disk balancing.

Seal:

Shaft at both ends of the stuffing box. Soft packing seal. There is a certain pressure of water from the water seal stuffing box through eight role. With the seal at the sleeve can be replaced to protect the shaft.

Transmission:

Pump motor through flexible coupling from the direct drive. Look at the pump from the drive side is clockwise.
