Double diaphragm pump with barrier chamber system
1" max. 135 l/min
Maximum safety for hazardous media: This special design was developed specifically for critical and hazardous media. The system is based on a double diaphragm construction: Behind the media-side diaphragm is a second safety diaphragm. The space between them is monitored by sensors, which immediately detect any diaphragm rupture. This enables the pump to be switched off automatically and reliably prevents any media leakage – without the use of an additional barrier medium. Monitoring of the air-side diaphragms is also available as an option. We offer these pumps with intelligent sensors for connection to the tim®LINK module as an option (details in the tim®TRON chapter). All information on the series can be found in the tim®CHEM chapter.
Added value of the barrier chamber system without barrier fluid
Operational safety and occupational health and safety
The barrier chamber system reliably prevents the medium from being released into the environment. The built-in sensors quickly and reliably detect even a small amount of medium entering the barrier chamber.
Media-independent applicability
Unlike established systems, this system does not use a barrier fluid in the locking chamber; power is transmitted mechanically with an optimised support disc.
contamination-free conveying
The barrier fluid-free design means there is no risk of the
barrier fluid-free
entering the media line.
Minimal operating & maintenance costs
By eliminating the need for a barrier medium, there is no need to select and fill process-compatible barrier media. Nor do the sensors need to be adjusted for specific media. The barrier chambers can be easily flushed, which simplifies decontamination.
Minimum
pulsation
The direct mechanical connection of the diaphragm, combined with the elimination of a barrier fluid, results in a significant reduction in pulsation.
start-up
reliability
Safe pump start-up is guaranteed even in critical operating situations. The bistable jump valve prevents problematic intermediate positions of the control valve.
