Type MF
Qmax=240m3/h – Hmax=37,5m
APPLICATION
MF pumps are designed to handle slurries containing high concentration of fine solids.
Typical application include:
- Copper ore processing plants
- Hydraulic transport of sand
- FGD installations in power plants
DESIGN
Stationary, horizontal, single-stage rubber lined slurry pumps with rubber impellers and spiral casing. The entire rotating assembly can be shifted in axial direction in order to adjust the sealing gap between the impeller and the front liner. The axial thrust is absorbed by roller bearings. The suction flange is situated horizontally at the pump axis. The delivery flange can be directed vertically upwards, horizontally or at an angle of 45o. The pumps are powered by motor by v-belt transmission. The pumps are equipped with a special frame allowing for moving the bearing casing and one half of the pump casing which enables rubber liners and impeller replacement without disconnecting the pump flanges from the pipelines. A stuffing box with gland water led to the lantern ring is applied as a standard for shaft sealing. Version with mechanical seal is also applicable.
MF pumps can be made in a vertical version.
