Pulsation dampeners
A diaphragm pump can not produce a continuous flow rate, as opposed to a centrifugal pump. If, however, a very exact delivery speed and quantity is required, a pulsation dampener is used.
The following models can be used for various types of air operated diaphragm pumps from our JP-800 series.
Standard:
II 3/3 GD c IIB T135 °C (Ex Zone 2)
Conduct:
II 2/2 GD c IIB T135 °C (Ex Zone 1)
avantages
High-viscosity media have a continuous flow rate.
The pumps are relieved by the dampener.
A dosing system is much quieter.
Pressure surges in the systems are damped or avoided.
