South African Paper Mill Overcomes a Long-Standing Issue with MasoSine Pump
The Watson-Marlow Fluid Technology Group, a world leader in niche peristaltic pumps and associated fluid path technologies, has replaced the progressive cavity pumps with its MasoSine pump at a leading paper mill based in South Africa. The new improvement solves the long-standing problem of viscosity at the paper mill.
The cooked starch that is used to gloss paper at the mill has a viscosity of 15,000 cP at 90 degrees Celsius, which can cause major problems. In addition, the starch tends to crystallize as it comes in contact with the atmosphere, or if the temperature drops below 30 degrees Celsius.
The paper mill pumps starch from both industrial and food applications from the boiler tank to the paper machine. There, it is sprayed on the paper with nozzles. In order for this process to be successful, consistent and reliable pumping at 15,000 l/h is needed.
In order to deal with the challenges associated with the paper mill, it replaced its existing PC pumps with a MasoSine SPS250 sine pump.
MasoSine products were the perfect choice for the paper mill. They offer very little internal friction and minimal fluid deformation, which makes them more efficient than other rotary pumps, in addition to offering excellent power density. MasoSine pumps tend to require less electrical power, especially with high viscous products. The pumps are therefore able to utilize a smaller motor, which leads to less energy consumption and a reduced carbon footprint during the pumping process.
In addition to its improved viscous product handling capabilities, the paper mill has also witnessed a marked reduction in suction blockages thanks to the suction capabilities of the MasoSine SPS250. The pump also has a lower pulsation than the previous PC pump, improving starch quality.
Due to the success of the new pump, the paper mill is now looking at installing MasoSine pumps at other plants. The mill has paper and pump manufacturing operations on three continents.
