020071-1 Check Valve Assembly for 87K waterjet pump

A waterjet pump with a rating of 87K typically means that it has a power output of 87,000 pounds per square inch (psi). A waterjet pump is a type of pump that uses a high-pressure stream of water to cut through various materials. It works by pressurizing water to a very high pressure and forcing it through a small orifice, creating a high-velocity jet of water that can cut through materials such as metal, stone, and glass.

Waterjet pumps with a rating of 87K are typically used for industrial cutting applications that require high precision and accuracy, such as in the automotive, aerospace, and manufacturing industries. These pumps are capable of cutting through a wide range of materials, including thick metal sheets, and are often used in applications that require high-speed cutting and intricate shapes.

It's important to note that the rating of a waterjet pump is not the only factor that determines its performance. Other factors such as pump efficiency, nozzle design, and water flow rate also play a significant role in determining how well the pump will perform in different applications.
