To minimize pipe vibrations it is necessary to design pipe runs so that the &#8220;acoustic length&#8221; of the pipe run does not create a standing wave that adds to the pressure pulsations in the system. The acoustic length is the total overall length from endpoint to endpoint including all elbows, bends, and straight pipe runs. [...]]]></description>

In many instances where the sizing recommendations previously discussed are used, there is not need to install dampeners to reduce liquidpulsations. However, in most instances, it is possible to further reduce pulsations and thus reduce pump maintenance costs and piping vibration with the use of pulsation dampeners. Dampeners are recommended for all major multipump installations, [...]]]></description>

		<description><![CDATA[It is absolutely imperative that the suction piping be sized to assure that the NPSH available exceeds the NPSH required by the pump. Often, this can be arranged by elevating the suction tank or by providing a lowhead centrifugal charge pump to feed the reciprocating pump. If the NPSH available is too low, valve breakage [...]]]></description>
