Water jet cutting systems
A highly concentrated water jet is ideal for cutting through materials cleanly and safely. For materials that are difficult to cut, abrasive agents are added to the water jet in a cutting injector. Firstly, a high-pressure water nozzle creates a water jet inside the assembly. This pressurized water jet travels through the mixing chamber into a focusing nozzle made from hard metal. This creates a vacuum in the mixing chamber, meaning air and abrasive particles are sucked in through a feed pipe on the side. In the mixing chamber, the high-pressure water jet accelerates the abrasive agent and transports it through the focusing nozzle.
The optimal use of available resources not only protects the environment, it is also a deciding factor for economic success. Fast-switching high pressure pumps from Hammelmann impress with their outstanding implementation of available energy and maximum reliability in daily operation.
Special advantages result from the combination of several pump units in a common rail system. The intelligent, central controller freely defines which pumps are used as pressure generators.
Mobile waterjet cutting combines the proven advantages of Hammelmann cutting systems and unique flexibility in one system. Configure your product with operating pressures up to 58k psi [4000 bar], volume flows up to 10 gpm [40 l/min] and many accessories such as guide rails, carriages or feed units.

Adapted power requirements and significant savings in energy costs
Adjusted power requirement
Hammelmann high-pressure pumps are particularly economical in terms of the energy used. When operating these high-pressure systems, there is the possibility of using only the exact motor power that is required for the current cutting process. Moreover, significant energy savings can be achieved as a result of the high mechanical and volumetric efficiency of the cutting pump.

Significant savings in energy costs
Water jet cutting systems often use hydraulically operated pressure converters. When controlling and providing the required power, only around 60 % of the energy taken is actually converted into direct cutting power. This represents an enormous loss of energy.
The directly driven Hammelmann plunger pumps feature up to 30 % higher efficiency compared to pressure intensifiers with load sensing systems.

Industrial water jet cutting
The optimal use of available resources not only protects the environment, it is also a deciding factor for economic success. Fast-switching high pressure pumps from Hammelmann impress with their outstanding implementation of available energy and maximum reliability in daily operation.
Hammelmann water jet cutting units with fast-switching high-pressure pumps have no need for complicated valve technology and are compatible with all cutting tables thanks to direct pressure control
The use of particularly fast-reacting reluctance motors in combination with the high efficiency of Hammelmann high-pressure pumps enables the simultaneous and demand-oriented supply of several cutting heads without pressure losses or start-up times.
The pumps are controlled by their own control unit and an intervention in the existing control of the cutting table is not necessary.
A retrofit or an exchange of pressure intensifier systems, is not a problem. Your cutting tables are ready for use again in a very short time and immediately operate more economically and energy efficient than before.
Common Rail system
Special advantages result from the combination of several pump units in a common rail system. The intelligent, central controller freely defines which pumps are used as pressure generators.
The intelligent, central controller freely defines which pumps are used as pressure generators. This ensures that use of all pumps takes place as uniform as possible and the pumps deliver the required power under optimal utilization.
As a result, there is a homogeneous load on all pump units on a daily average. In this way, the wear of individual components is reduced and maintenance intervals are maximized, which leaves a positive impact on service and repair costs.
Since individual pumps can be purposefully removed from the existing network, maintenance during operation is possible. This option also has a positive effect in the event of an incident.
If a pump fails in the system, the power it provides is distributed without any delay in the network, without system shutdowns occurring.
Master control unit
The master control is the control center in the common rail system. A touchscreen can manage and monitor up to eight pumps. Each integrated pump has its own data logger, which provides detailed information about the life cycle of the pump. Pumps can be conveniently taken out of the system by the central control unit to make these available for service, for example.
Specially designed submenus ensure intuitive operation and clear presentation of the information provided.

Configuration options
Cutting nozzles
Operating pressure:
22k - 58k psi
[1500 - 4000 bar]
Flow rate:
3 - 10 gpm
[10 - 40 l/min]
Applications:
Cutting concrete, cutting through steel structures, applications on the cutting table, e.g for cutting sheet metal, glass and tiles
Guide rail
To make horizontal cuts, the guide chain is attached to a 6.5 ft. [2 m] guide rail.
Carrier trolley
The carrier trolley speed is manually controlled by a pneumatic system. The cutting speed and positioning speed can be selected individually and are controlled separately.
Feed unit
The abrasive cutting head is mounted on a pneumatically driven carrier trolley that runs on a tensioned guide chain. A constant feed can be achieved in this way.
