Today, two types of pumps are used in waterjet cutting: linear booster pumps and rotary direct drive pumps. Both booster pumps and direct drive pumps can reliably deliver ultra-high pressure water, and both have been successfully used in industry. The two pumps have something in common. They all have motors, water filters, control systems and sensors, and other similarities.
Before starting to study the two pumps separately, let's take a look at how the industry defines the difference in pressure levels. Please note that the pressure range follows a typical high-pressure pipeline operation (water pipeline, T-shape, elbow, etc.).
• Low pressure is a pressure below 10,000 psi (69 MPa).
• The medium pressure is between 10,000 to 15,000 psi (69 to 103 MPa).
• The high pressure is between 15,000 to 40,000 psi (103 to 276 MPa).
•Ultra high pressure is between 40,000 psi and 75,000 psi (276 to 517 MPa). For waterjet cutting, most pumps are between 55-60,000 psi (379 to 413 MPa).
Linear booster pump
Linear booster pump is the original technology used for waterjet cutting, and it is also the most common technology. The booster pump uses the elegant "pressurization principle" to pressurize the water. Let's take a look at how this theory works.
The hydraulic oil is pressurized to a pressure of 3,000 psi (in this example). The low-pressure oil pushes toward the piston biscuit, and its surface area is 20 times larger than the surface of the high-pressure plunger pushed toward the water. Therefore, the oil pressure of 3,000 psi was "enhanced" twenty times, resulting in a water pressure of 60,000 psi. The "strengthening principle" or ratio uses the difference in biscuit/plunger area to intensify or increase pressure.
The main components of the linear booster pump complete system are as follows:
• Electric motors between 25 to 200 hp (18 to 150 kW). For water jet cutting applications, the most common is 50hp (37 kW).
• The hydraulic pump connected to the motor sends the hydraulic oil to the booster.
• Supercharger, which uses the supercharging principle (as described above) to transfer the energy of the oil to the water.
•Inlet water treatment prepares ordinary tap water for the pump.
• A control system for controlling the start/stop of the pump, water pressure output and monitoring the integrity of the pump through sensors.
Rotary direct drive pump
Rotary direct drive pumps are first used for field applications in paint removal, mining and industrial cleaning. About 20% of the sprinkler systems installed worldwide use direct drive pumps. Today, this pump technology is also used in factory cutting and field cleaning applications. Unlike pumps based on boosters, direct drive rotary pumps do not have hydraulic pumps. Sometimes called a three-cylinder pump, an electric motor rotates a crank with three pistons to produce ultra-high pressure water. If you are fully familiar with the high-pressure washer, which is used to clean the gum on the sidewalk or to wash the house before painting, you should treat it as the same type of pump.
The main components of the rotary direct drive pump complete system are as follows:
• Electric motors between 25 to 500 hp (18 to 370 kW). For waterjet cutting applications, the most common is 30 hp (22.4kW).
• Power plant, including crankcase (usually with gear box) and three-cylinder ultra-high pressure fluid end.
•Inlet water treatment prepares ordinary tap water for the pump.
• A control system for controlling the start/stop of the pump, water pressure output and monitoring the integrity of the pump through sensors.
Booster pump comparison
The real comparison should be left to the experts who sit down with you to review your application. I will only provide some general high-level opinions.
• Booster pumps can provide higher pressures than direct drive pumps.
• Direct drive has higher electrical efficiency.
• The maintenance interval of the turbocharger is longer.
• The size of the direct drive is small.
• The booster is more suitable for applications where the cutting head has many on/off cycles.
Most importantly, these two pump technologies have their pros and cons. When you are ready to add a waterjet, it is best to discuss your special needs with an expert who has experience in the application of two pump technologies in order to find the right component for your work.
