It is intended as a guideline to be used with all available information to determine suitability of elastomers and wetted portions of Wilden Pumps for various applications. We suggest thorough research which should include known applications when determining pump construction. This chart is to be used at your discretion and risk.

These conditions will vary depending on the abrasiveness of your process fl uid, temperature, size of diaphragm, pumping media, and lift conditions. Consult your authorized Wilden distributor regarding which diaphragm material will work best for your application A GENERAL RULE:1. Neoprene or Wil-Flex diaphragms should gener-ally be used unless the chart shows them to be u nsatisfactory.

3 Even though Buna-N, Nordel and Viton may show A ratings, if neoprene or Wil-Flex have at least a B rating, it will probably be the most economical choice on a cost of diaphragms per gallon pumped This is especially true when considering the use of Viton diaphragms due to their replacement cost being over six times that of neoprene. Viton should only be considered for aggressive media at extreme temperatures if it shows an A rating and neoprene, Buna-N and Nordel show an unsatisfactory guides for best diaphragm selection do not hold for the valve ball material. Because the diaphragms are securely gripped by their inner and outer beads, they can stand up to 20% swell without affecting pump performance.

4 If the valve balls swell even a very small amount, they cannot function properly. Therefore, there will be cases where Neoprene diaphragms will be the best selection but Tefl on , Buna-N, Nordel or polyurethane balls will be required. CAUTION: Temperature limits are based upon mechanical stress only. Certain chemicals will signifi cantly reduce maximum safe operating temperatures. Consult engineering guides for CHEMICAL compatibility and temperature must be emphasized that none of these fi gures are absolute and are only general OF PLASTIC MATERIALSMany factors can affect the CHEMICAL RESISTANCE of plastics. These include, but are not limited to, exposure time, extremes of temperature and pressure, frequency of temperature and/or pressure cycling, attrition due to abrasive particles, and the type of mechanical stress imposed.

5 The fact that certain combinations of chemicals and mechanical load can induce stress cracking in many otherwise chemically resistant materials, both metallic and non-metallic, is of particular signifi CHEMICAL /temperature ratings presented are based on well-processed or well fabricated test specimens being essentially resistant to either CHEMICAL attack and/or severe swelling which would normally impair their performance under moderate mechanical parameters are dependent upon the particular application of polypropylene or PVDF and may differ from those experienced in either laboratory testing or apparently similar fi eld service. Because corrosive fl uids or vapors are often mixtures of various individual chemicals, it is strongly recommended that trial installations be evaluated under actual service example, immersion testing in individual chemicals at a specifi c operating temperature doesn t predict the performance of polypropylene or PVDF should an exothermic reaction take place when mixtures of chemicals are ratings given on the following pages are a guide and do not constitute a warranty of any kind, expressed or implied, with respect to the performance of the materials Wilden offers in any specifi c 2005 Wilden PUMP & ENGINEERING CO.
