Customized Wear Resistant Compound Improves Chamber in Popular Sotera Chemical Pump


WINONA, MINNESOTA, USA - (May 13, 2008) - When Tuthill Transfer Systems, a manufacturer of pumps and meters for the fast transfer of petroleum fuels and agricultural and industrial chemicals, wanted to improve the plastic chamber of their popular Sotera chemical pump, they chose a customized wear-resistant PPS compound from RTP Company.

The Sotera(r) pump is designed to transfer thin to thick products including slurries and encapsulated chemicals. Fluids and chemicals such as weed and insect control chemicals, automotive fluids, mild acids and a variety of industrial materials can easily flow through the Sotera system.

Re-designing the plastic chamber required rugged chemical compatible materials.
Wear resistance was also a critical requirement for improving the life of the product. "We were able to work closely with RTP Company and discuss exactly what we needed in terms of functionality," said Dick Curtin, President of Tuthill Plastics Group. "RTP Company customized a wear resistant PPS compound with the best additives to meet the product needs. Our customers now have a better, longer-life product."
