When investing in a waterjet cutting machine, the most critical decision you will make concerns the "heart" of the system: the high-pressure pump. Two main technologies dominate the market: the Intensifier Pump and the Direct Drive Pump.
At YH waterjet, we understand that choosing the right pump affects your operational costs, cutting speed, and maintenance schedule. Here is a technical breakdown to help you decide.
1. The Intensifier Pump: Unmatched Power and Thickness The intensifier pump is the most commonly used type of waterjet pump in the industry due to its robust design and longer maintenance intervals. It is ideal for heavy-duty industrial applications.
- Extreme Pressure: YUANHONG has developed ultra high pressure water jet pumps capable of reaching 87,000 PSI (and up to 94,000 PSI) based on industry demand.
- Deep Cutting: This immense pressure significantly increases the maximum cutting thickness, allowing you to cut materials up to 400mm~500mm thick.
- Multi-Head Operation: Intensifier pumps maintain stable water pressure even as the flow rate changes, which is critical if you plan to operate multiple cutting heads with a single pump to boost productivity.
2. The Direct Drive Pump: Efficiency and Simplicity Working similarly to a car engine, a direct drive water jet pump uses a motor to rotate a crankshaft connected to pistons, generating pressure directly in the water.
- Energy Saving: The yuanhong Direct Drive Pump is designed for high efficiency. Our 30hp motor can reach the cutting pressure equivalent to a standard 50hp motor, making your equipment significantly more energy-saving.
- Low Maintenance: With a simpler structure and no attenuator, there are fewer parts to maintain or replace, reducing your downtime.
- Application: These pumps are typically used in lower-pressure applications (55,000 PSI and below) but are powerful enough to cut metal, stone, and glass with ease.
Verdict: Which One Should You Choose?
- Choose the yuanhong Intensifier Pump if: You need to cut very thick materials (up to 500mm), require ultra-high pressure (87k+ PSI), or plan to run multiple cutting heads simultaneously.
- Choose the yuanhong Direct Drive Pump if: You prioritize energy efficiency, have a limited power supply, or prefer a machine with a simple structure and lower maintenance complexity.
