The use of dosing pumps involves pulsations. The rule is: the longer the line, the larger the pressure peaks. These may impair the operation, in some cases even the pump and / or the line network may be destroyed.
The PDS inline pulsation dampeners from Lutz-Jesco is a simple and also effective way to reduce pressure fluctuations to a harmless level. Due to a choice of different materials it is possible to ensure chemical resistance even in the case of very aggressive media. As the unit is integrated directly into the line the diaphragm storage is flushed continuously, and extra costs because of difficult installation work are avoided.
When mounted close to the pump, optimum results can be achieved. The PDS can be installed on the discharge as well as on the suction side. On the suction side, it often makes reliable metering only possible due to the improved flow conditions. Thus cavitation is also avoided, for example.
The PDS is needed whenever pulsating flow is undesirable or rigid piping and long suction and discharge lines are used. Its maximum stroke volume is 1,200 ml/stroke.
