Central Pump Station

Our services are based on competence, experience, innovative thinking, modern production equipment and motivated employees.

Numerous certificates and approvals give you the security that applicable rules and regulations are observed throughout the entire production processes.

Our product range is focused on above and below-ground applications in water and waste water management, the power industries, tunnel construction, well sinking, domestic installations and mining.

Benefit from a strong, competent partner who fullfils your special requirements: from design planning and professional production to punctual delivery.

The concept of a „central pump station“ has been used all over the world to supply the hydraulic face support with HFA fluid for many years. In principle, this concept involves the use of rapid-action connecting lines to transport the hydraulic fluid over several kilometres without major pressure losses.

More and more projects are being implemented where a „central pump station“ supplies HFA fluid to several faces at the same time. As a result, even greater cost savings can be achieved. Moreover, this concept is also installed to supply cooling water and combat dust at the face.

The transport of hydraulic fluid is not the only use for this system. It is also suitable for the transport of concrete, water, spraying lines and other applications outside the mining industry.



The High Pressure system is a product of Carl Hamm, which has been operating successfully in the mining industry for over 90years. Our high-quality products are recognized throughout the world.

The High Pressure System is used for the entire emulsion circuit:

  • As a supply line from the pump station to the hydraulic system
  • As a return line from the hydraulic system to the pump chamber

Every project starts with the planning of the volume and pressurerequirements and the preliminary planning of the pipe routing.

The second stage involves calculating the pressure losses and determining the optimum nominal sizes to achieve the performance required. The final stage comprises the detailed planning; valves are positioned and the routing adapted to suit local conditions / peculiarities. The entire procedure is coordinated with the customer and, if necessary, a site tour is also not a problem.

Efficiency, quality and safety are not just empty words for us. As we are aware of our responsibility, we test 100% of our tubes and fittings with a cold-water-pressure test.
