1. Submersed in the slurries, the MF series froth pump is typically used to convey abrasive or corrosive frothy slurries.
2. A typical feature of this vertical centrifugal slurry pump is the double-casing design which allows the case to be split open along its centerline. Wet-end parts are replaceable and made of abrasion-resistant high-chrome. Depending on your specific pumping task, we can rubber and polyurethane to construct the internal pump liner and impeller.
3. The impeller vanes and hopper are specially made to remove any foam produced during pumping operation.
4. Eliminate the need for any shaft seal and sealing water.
5. Parts submerged in the slurry can be made of metal or rubber.
1. Simple pump system layout allows easy installation.
2. Transmission parts of this submersible pump are interchangeable with those of MV series. Installed above the bearing assembly is a motor mounting base or support frame.Flexible coupling or V-belt is used to connect the motor shaft and the pump shaft. Pump shaft speed is easily adjusted by changing the grooved pulley so as to suit the varying pumping applications.
3. The hopper features a steely structure, complete with the tangential inlet and overflow box. The overflow box can easily send the excessive slurry back to the recycling tank. The tangential inlet allows the frothy slurry to enter into the froth pump while separating the air out of the slurry.
4. The pumping unit is interchangeable with the MA series. According to the kind of medium to be pumped, we can use metal, rubber, or other non-metallic materials to make the wet-end parts of this froth pump.
5. The pump is able to function properly when there is insufficient suction.
Hydraulic Modeling
1. Air is separated from the slurry in a vortex created by the specially designed impeller and the tangential inlet.
2. Vertical cantilever design eliminates the need for shaft seal or sealing water.
Transmission
Grease lubricated bearing assembly: The double-row tapered roller bearing is attached to the pump shaft while the single-row cylindrical roller bearing connects to the motor shaft.
Installation Types
DC: The motor mounting base is set above the bearing assembly, so it is easy to replace or repair the motor parts.
BD: A V-belt is used to connect the motor shaft and the pump shaft. The motor support frame is installed above the bearing assembly, allowing easy replacement of grooved wheels. The purpose of swapping grooved wheels is to change the rotary speed of the pump shaft in order to suit varying pumping applications or conform to the worn-down pump.
