Peristaltic pumps for biodiesel plant

21st February 2013


The design consultant for a new biodiesel plant in Argentina faced the challenge of selecting a pump for the metering and transfer of aggressive chemicals and slurries used throughout the ethanol production process. The pump must handle a range of harsh products and provide precise dosing capabilities, ensuring that the set flow is maintained regardless of system pressure fluctuations.
 
Conventional progressive cavity pumps and diaphragm dosing pumps are often recommended for similar applications but the possibility of a decreasing flow with pump wear meant that flow meters would have to be installed as a safety measure to avoid costly, inaccurate dosing.

Given the demanding nature of the application the designer chose the Verderflex peristaltic pump range. This particular design of pump not only addressed the specific concerns of the designer but also provided significant savings on auxiliary products.

The seal-less design of the Verderflex peristaltic pump, with no valves or moving parts in the product stream provided an impressive list of cost saving and performance benefits for the end user.
 
Verderflex peristaltic pumps were successfully selected to pump sodium methylate, water and soaps, fatty acids and HCL during the first stage of the production process.
