Disposable pump excels with wear resistant PPS compound from RTP Company
© RTP
AC Engineering has developed a sanitary disposable pump engineered with a wear resistant polyphenylene sulfide (PPS) compound from RTP Company. The material simultaneously satisfied difficult performance requirements while meeting the FDA-approved standards.
"Only as a result of the close cooperation between RTP Company engineers and AC designers was it possible to develop a product that meets all of our chemical, dimensional, and mechanical requirements," said Cameli Adahan, President of AC Engineering.
The custom RTP 1300 Series PPS glass fiber reinforced compound with PTFE lubrication using FDA-compliant polymers and ingredients has good wear resistance while maintaining low warpage and low creep at operating temperatures of 110 °C (230 °F). The material has low moisture absorption to minimize swelling, offers exceptional chemical resistance and dimensional control while the low coefficient of thermal expansion keeps the fit/gap between pump parts consistent over a wide temperature range. Additionally, the internal lubricants specified in this formula provide good plastic-on- plastic wear resistance.
Traditional metal pumps used in the food, dairy, chemical, medical, and pharmaceutical industries face contamination issues which create down-time for maintenance and high cleaning costs. AC’s scroll pump offers several key advantages over other types of pumps. External lubricants are not required, it does not contain valves, and pressure spikes are eliminated. The pumps bring significant value to their customers. The pump heads can be replaced without using tools, eliminating cleaning problems.
