Multihead Installations. Diaphragm Pumps for High Pressure & PTFE have Puls Dampeners with PTFE double layer membrane and secondary containment seal. High Pressure Diaphragm Head Process Pumps that are also hermetically sealed, must be matched by the same considerations for safe features in the pulse dampeners design. The design below is single connection.
A diaphragm pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or Teflon diaphragm and suitable non-return check valves to pump a fluid. Sometimes this type of pump is also called a membrane pump.
