A pump is used to supply anode material (carbon slurry) to a bead mill, where the material is dispersed.
Conventionally, a rotary volumetric pump was used, which posed the following problems.

• A screenless bead mill was used, so a small amount of beads may have been discharged. This may have led to emergency stops due to beads being bitten inside the pump, which may have resulted in pump damage.
• The pump parts wore out immediately due to the particles contained in the liquid, which led to frequent part replacement.
• Frequent disassembly and cleaning were necessary, but the shaft seal was difficult to clean, which caused problems.

We suggested that the customer use one of our Smoothflow Pumps, which have a successful history of transferring battery material slurry, and they agreed to this proposal.

• We customized the pump valve seat shape to match the diameter of the beads used to ensure that no biting occurs even if beads flow into the pump.
• There are no sliding parts, so the wear is minimal even when transferring slurry. This reduces the frequency of part replacement.
• There are no shaft seals, so the pump is easy to clean. This makes it possible to complete the cleaning work in a short period of time.
