Waterjet Pumps

Powered for Performance, Efficiency, and Uptime

Every cutting operation relies on a steady, reliable supply of high-pressure water. Choosing the right waterjet pumps comes down to finding the perfect balance between pressure, water flow, and motor power for your specific manufacturing demands.

Whether you run a single 2D cutting head or a high-volume gantry with multiple cutting heads running simultaneously, our high-pressure pumps deliver continuous, stable pressure day in and day out. As your long-term technical partner, we ensure your pump setup fits both your current production goals and your future growth.

High-Pressure Pump Technologies

Understanding pump performance helps you optimize your cutting speed and lower your cost per part. We offer two primary pressure classes depending on your material and cycle time requirements:

1. 4,000 Bar Waterjet Pumps (Direct Drive & Intensifier)

Proven Industrial Reliability: The standard workhorse for a wide range of job shops and industrial cutting setups.
Cost-Effective Versatility: Delivers predictable, stable high-pressure water for everyday 2D abrasive cutting and pure water applications on thin-to-thick materials.

2. 6,000 Bar High-Pressure Systems

Maximum Cutting Speed: Higher pressure accelerates the waterjet velocity, transferring significantly more kinetic energy to the abrasive media.
Boosted Productivity: Increases cutting speeds dramatically on hard metals and thick plates, helping you cut parts faster and reduce cycle times.

Key Performance Factors: Pressure vs. Flow

When selecting a waterjet pump, understanding how pressure and flow work together helps you maximize machine productivity:

Waterjet Pressure (Bar / PSI)

Primary Impact: Controls the velocity and energy density of the water stream.
Core Benefit: Higher pressure accelerates abrasive particles, allowing you to cut through hard materials significantly faster.
Best Used For: Reducing part cycle times, improving edge finish quality, and slicing through tough, thick materials.

Water Flow Rate (Liters per Minute)

Primary Impact: Controls the total volume of high-pressure water available.
Core Benefit: Higher flow rates provide the volume necessary to feed larger orifice sizes or run several cutting heads at once.
Best Used For: Operating multi-head waterjet systems and maximizing part output per cutting cycle.

Frequently Asked Questions

What is a waterjet pump?

The high-pressure pump is the heart of a waterjet cutting system. It generates the pressurized water that is forced through a small precision orifice, creating the high-speed waterjet used for cutting.

Pump pressure, flow, and power directly influence cutting performance, productivity, and how many cutting heads can operate simultaneously.

How do I choose the right pump for my waterjet cutting machine?

Start with what you need to cut – material, thickness, required cutting speed and number of cutting heads.

A 4,000-bar system is a proven solution for a wide range of applications, while 6,000 bars can provide significantly higher cutting performance where productivity is important. The right choice is finding the best combination of pressure, flow, and power for your production.

It is also important to consider energy consumption, maintenance requirements, available floor space, and possible future production needs.

What is the difference between 4,000 bar and 6,000 bar waterjet pumps?

Higher pressure creates a faster and more concentrated waterjet.

In abrasive cutting, this transfers more energy to the abrasive particles and can significantly increase cutting speed. The actual improvement depends on material, thickness, nozzle configuration, abrasive flow and required cut quality.

The best choice depends on the material, thickness, cut quality requirements and overall production goals.

Pressure or flow – what is the difference?

Pressure and flow describe two different characteristics of a waterjet pump. Pressure determines the velocity and energy density of the waterjet, while flow determines how much high-pressure water is available.

Higher pressure can improve the performance of each cutting head, while higher flow allows larger orifices or multiple cutting heads to operate simultaneously.

Can one pump support multiple cutting heads?

Absolutely – as long as the pump has enough flow and power. Every cutting head requires a certain amount of high-pressure water. When adding more heads the total flow requirement increases.

Correct pump sizing ensures that the required pressure is maintained when all cutting heads are cutting.

Does a bigger pump mean higher energy costs?

Not necessarily. A larger or higher-pressure pump may use more power while cutting, but if it cuts the part significantly faster, the energy consumption per produced part can still be lower.

That is why productivity and cost per part are often more useful measurements than motor power alone.

What maintenance does a waterjet pump need?

High-pressure pumps work under extreme conditions and require regular preventive maintenance. Typical service includes high-pressure seals, valves, filters and inspection of high-pressure components.

Water quality is also important. Good filtration and correct water treatment can significantly increase component lifetime and reduce unplanned downtime.
