Free Maintenance Resonator

Extending the mechanical life of valves, actuators and other hydraulic components and reducing vibrations and pressure pulsations into the system.

Where zero maintenance equipment is required for high pressure systems, free maintenance resonator would be an alternative to use. Free maintenance or better called resonator pulsation dampeners are typically installed on the suction and discharge sides of the API 674 reciprocating triplex process pumps, and are used, instead of bladder or diaphragm pulsation dampeners.

The manufacturing of maintenance free resonators is in compliance to the Pressure Equipment Directive PED number 97/23/CE, European ATEX Directive 94/9/CE, ASME Code VIII Div.1 or Div.2 U Stamp if needed, CU-TR 032/2013 and SELO, if required.

Contrary to the pulsation dampers, the operating principle of the resonator would be the resonance. The frequencies compensation generated by the pulsations are reduced by the internal design of the resonator and a key factor is the pumped fluid compressibility value (bulk modulus) that has to be considered while sizing the resonator.

Pulsation Dampers

Very high reduction of the discharge pulsation; the exact value depends especially on the pumped fluid features and piping connections. It is typically higher than 60%
