Almatec Barrier Chamber System: E Series

Almatec Barrier Chamber SystemThe Almatec Barrier Chamber System for E Series pump sizes 10-50 meets high safety requirements. The standard single diaphragm set-up is replaced by two diaphragms arranged in tandem with a barrier chamber of conductive Polyethylene between them, and filled with non-conductive liquid.

The barrier chambers must always be filled entirely to transmit the air pressure to the pumped fluid, therefore, it is monitored by a level sensor. If the diaphragm on the product side fails unexpectedly, the pumped fluid enters the barrier chamber and the non-conductive liquid flows into the pumped fluid. The change in conductivity of the barrier liquid is detected by sensors and signaled to a controller which triggers an alarm or cuts off the air supply to the pump
