Restore the original productivity of water extraction systems by up to 100% with our material-friendly high-pressure internal flushing.
KAMAT offers modular high-pressure components for mechanical well regeneration. The system enables the complete removal of incrustations and biological deposits (e.g., iron bacteria) through hydromechanical high-pressure internal flushing. KAMAT technology allows for a reactivation of productivity by up to 100% with operating pressures of up to 500 bar. The core components of the system include the mobile KAMJET high-pressure unit, a special double rotation nozzle for well rehabilitation, and, if required, powered hose reels.
The Challenge: Performance Loss due to Well Aging
Production wells form the backbone of many water recovery systems in industry, agriculture, and water supply. During operation, these systems are subject to a natural aging process that continuously deteriorates the hydraulic connection to the aquifer:
- Chemical and Biological Incrustations: Oxidation leads to deposits of iron and manganese oxides, while iron bacteria (e.g., Gallionella) clog filter pipes and filter gravel.
- Physical Blockages: The entry of fine sands and clays (particle migration) and the caking of the grain structure reduce the pore volume in the filter gravel.
Economic Consequences: Falling flow rates and rising energy costs endanger the profitability of water extraction. Specific performance often drops by more than 50%.
Technological Advantage in Well Rehabilitation
Efficiency in water extraction is measured by the recovery rate and the service life of the systems. With KAMAT high-pressure technology, you rely on a system developed for the highest demands in professional maintenance.
Instead of relying on costly chemical processes with complex approval procedures, KAMAT offers a purely hydromechanical, material-friendly solution based on high-pressure water technology. Our process is particularly advantageous in drinking water protection zones, as it functions entirely without environmentally harmful chemical additives, meaning no costly flushing or approval procedures are required.
Why this system defines the standard:
- Maximum Depth Effect: While simple cleaning methods often only reach the inner pipe walls, the KAMAT double rotation nozzle reaches deposits deep within the filter gravel pack through targeted cavitation and pressure pulses.
- Environmental Compatibility: The process works purely hydraulically. This not only saves costs for cleaning chemicals but also enables use in sensitive drinking water protection areas without complex approval procedures.
- Robust Modular Principle / Efficiency: Minimize downtime through the standardized KAMAT modular system. Thanks to interchangeable components, spare parts inventory is lean, and service is possible without special tools.

FAQ – Professional Well Rehabilitation
According to DVGW Worksheet W130, a distinction is made between chemical, mechanical, and combined methods. While chemical methods use acids or oxidizing agents, mechanical methods rely on brushes or hydromechanical high-pressure technology. KAMAT focuses on hydromechanical high-pressure inner flushing, which removes deposits purely physically through kinetic energy and cavitation.
High-pressure inner flushing is considered particularly effective because, unlike simple brushing, it achieves a deep cleaning effect in the filter gravel. By using a double-rotation nozzle, not only is the inner pipe wall cleaned, but the “clogged zone” in the aquifer is also reactivated by pressure wave impulses. This method is 100% chemical-free, protects the well construction material, and does not require complex approval procedures in water protection areas.
Three core components are essential for a high-performance overall system: High-pressure unit: A mobile system such as the KAMJET (e.g. with a K18000 pump) delivering pressures of up to 500 bar at high flow rates. Well cleaning nozzle: A self-propelled double-rotation nozzle that rotates by recoil force and cleans the filter section continuously. Automatic hose reel: It ensures precise guidance of the high-pressure hose and enables documented cleaning cycles at depths of up to 500 m.
Professional regeneration usually restores well yield to 80% to 100%. This avoids the high investment costs of building a new well while also reducing ongoing operating costs. By lowering the entry resistance at the filter slots, the specific energy demand of the feed pumps can be reduced by up to 50%.
Yes, the equipment is highly adaptable. With the KAMAT modular system, nozzle extensions and centering guides can be matched to well diameters starting from 150 mm. Thanks to its robust design and high pressure reserves, the system is suitable for both shallow horizontal drains and vertical deep wells in municipal and industrial water management.
The system is highly flexible and can be adapted to different pipe diameters from 150 mm upward by using interchangeable nozzle extensions.
It enables precise and even hose guidance down to depths of 500 m, protects against kinks, and significantly improves operational safety.
Yes, the KAMJET is designed as a mobile high-pressure system that is either mounted on a trailer or installed in a vehicle, allowing it to operate fully autonomously.
An integrated spacer system ensures that the nozzle remains centered inside the well pipe during operation, preventing mechanical damage.
