90K Water Jet Accessories 20475874 Backup Ring Brass

The Backup Ring Brass 20475874 is one of water jet accessories in a 90,000 psi waterjet pump to provide additional support and sealing to the high-pressure water system.

The backup ring is typically located in the intensifier pump and helps to prevent leaks in the water system by providing additional support to the high-pressure seals.

1. Material

The Backup Ring Brass 20475874 is typically made of brass, which is a durable and corrosion-resistant material that is able to withstand the high-pressure and high-temperature conditions of the waterjet cutting process.

The brass material is also able to provide good sealing properties, helping to prevent leaks in the water system.

2. Function

The Backup Ring Brass 20475874 is designed to provide additional support and sealing to the high-pressure seals in the intensifier pump.

It is typically installed behind the high-pressure seal and helps to distribute the pressure evenly across the seal, preventing it from extruding or being damaged by the high-pressure water.

3. Wear and tear

The Backup Ring Brass 20475874 can wear over time due to the abrasive nature of the waterjet cutting process.

Wear on the backup ring can lead to leaks and other issues with the water jet accessories.

It is important to inspect and maintain the backup ring regularly to ensure optimal performance of the waterjet cutting system.
