20498314 Attenuator for waterjet intensifier pump

Win Win waterjet provide many kinds of waterjet parts, OEM/ODM available 

The 20498314 Attenuator is a component of a waterjet cutting machine that is used to regulate the pressure of the water stream. The attenuator is typically located between the intensifier pump and the cutting head, and it helps to smooth out pressure fluctuations in the water stream to ensure a consistent and stable flow of water during the cutting process.


Waterjet cutting machines typically use a high-pressure water stream to cut through materials, with pressures ranging from 30,000 to 90,000 psi or more. However, these high pressures can cause fluctuations and surges in the water stream, which can lead to inaccurate cuts or damage to the machine.


The 20498314 Attenuator helps to regulate the pressure of the water stream by absorbing these fluctuations and providing a more stable flow of water to the cutting head. The attenuator may contain a diaphragm or other mechanism that can expand and contract to accommodate changes in pressure, helping to maintain a constant pressure in the water stream.


Proper installation and maintenance of the attenuator are important for achieving accurate and consistent cuts in a waterjet cutting machine. The attenuator may need to be periodically inspected and replaced to ensure that it is functioning properly and providing the necessary pressure regulation for the cutting process.
