English Translation of Title:
Flat Washer – M12, for waterjet pump 1‑Liter Attenuator, Water Jet Cutting Machine Parts, Model No. 49898729-Flat-Washer-M12-Waterjet-Pump-1-Liter-Attenuator.842.3-1

Introduction, Application, Features, and Maintenance:

This component is a flat washer designed for water jet cutting systems. It is a thin, disc‑shaped fastener with a central hole sized for M12 bolts or screws, specifically used in the mounting or assembly of the 1‑liter attenuator on waterjet pumps.

Application:
Used under bolt heads or nuts in the mounting of the 1‑liter attenuator assembly to the waterjet pump or related components. It provides a smooth bearing surface, distributes load, reduces friction, and prevents damage to mating surfaces.

Features:

• Sized for M12 bolts or screws (12 mm nominal diameter).

• Distributes clamping load evenly over a larger surface area.

• Prevents surface damage to components from bolt heads or nuts.

• Manufactured from high‑strength, corrosion‑resistant material suitable for harsh water jet environments.

• Reduces friction during tightening for accurate torque application.

• Standard dimensions ensure compatibility with M12 fasteners.

Maintenance:

• Regularly inspect the washer for signs of corrosion, deformation, or wear.

• Check for proper seating under bolt heads or nuts.

• Replace immediately if the washer is deformed, cracked, or corroded.

• Ensure the washer is the correct size for the bolt being used.

• Use a new washer when reassembling components to ensure proper load distribution.
