Frequently Asked Questions

1. What is this Bürkle double-diaphragm pump used for?

It is used for transferring liquids in a compatible pumping setup. Suitability depends on the liquid properties, required transfer conditions and the materials in contact with the liquid.

2. Which materials are used in this pump version?

The housing and valve seats are PVDF, while the valve balls and seals are PTFE. Check the complete wetted-material specification when assessing the application.

3. How should chemical compatibility be assessed?

Check the actual chemical, its concentration and the operating temperature against the manufacturer’s compatibility information. Housing material alone is insufficient because diaphragms, valve parts and seals also contact the liquid.

4. Can this version be substituted for another Bürkle pump?

Confirm the complete material configuration, connections and operating requirements before substituting a pump. Similar-looking models may use different seal or diaphragm materials that change their suitability.
