Diaphragms, valve balls, valve seats and valve seat O-rings are called pump elastomers. WILDEN diaphragm pumps can be fitted with a wide range of elastomers to meet your specific application. What to consider when choosing a particular elastomer: temperature limits, chemical resistance, service life, abrasive suitability, cost, suction capacity and sanitary suitability.
The type of diaphragm has a major impact on the final performance and maintenance costs of your air-driven diaphragm pump. Need help choosing the right diaphragm? We are happy to assist you by phone.
