The buffer chamber system with diaphragm monitoring is available in the following models:
BC 1 – Buffer chamber system with diaphragm monitoring, with sensors
BC 2 – Buffer chamber system with diaphragm monitoring, with sensors and switching device
BC 3 – Buffer chamber system with diaphragm monitoring, with sensors, switching device
and an intrinsically safe isolating amplifier (potentially explosive areas)

Note:
The maximum permissible operating temperature for pumps with buffer chamber system with diaphragm monitoring is +70 °C for PE pumps and +80 °C for PTFE pumps.
