Carl Hamm provides solutions to reach deep water

Carl Hamm provides Deep Water Abstraction Solutions

When you know there is water deep down under the soil and it can take your farm to new heights of production, then you need to speak to the experts. Most borehole drilling and irrigation companies on the agricultural scene reach their limit of predictable service at 120 to 150 metres deep. In Israel, water from ancient natural aquaducts more than 1,5 km under the surface changed the Hula Valley into a farming oasis in the middle of a desert. Some of the challenges of working that deep include the capability to drill deeper, the testing of the water and the soil stability, and the pure weight of the equipment being suspended in the borehole. Chris Munnick, CEO of Carl Hamm SA, says: “The equipment needed to service a hole that deep is expensive. You don’t want to lose it down there.” The specialised pipes and connections developed by Carl Hamm have been tested thoroughly in the mining sector where working at those depths are not so unusual. Chris says that if you are abstracting 100 to 300 cubic meters of water from over 350 m and you are suspending a 380 kW pump and motors, you have a suspended weight in excess of 20 tonnes. You need couplings that can carry weight and handle pressure. As example we can suspend a 1 mW pump at 1 300 m with a suspended weight of 131 tonnes handling in excess of 150 bar. Sleeves and pipes need to be thick, strong and as smooth as possible, and pumps need to be reliable.

Here are some of the solutions offered by Carl Hamm:

High pressure ZSM connector The specialised, pull-proof, tightsleeved Carl Hamm ZSM connector can replace the space-wasting traditional flanges. It can be used as a vertical riser pipe in open pit and underground mines as well as in deep wells. The patent-protected tight sleeve system is a unique alternative to other conventional connection systems due to its quick and easy assembly/disassembly and space-saving design. All of this ensures considerable cost savings through the whole life-cycle. No tools are needed to connect the pipes.

Spigot end (male part) O-ring to protect the chain grooves against impurities Chain entry Shearing elements to create the axial nonpositive connection

O-rings to seal against the internal pressure

Sleeve (female part)

Intricate technology is involved in the unique ZSM connector.

Drilling and pipeline solutions Carl Hamm designs, installs and manages pipeline solutions for above and below ground mining, water and waste-water treatment, and industrial sectors. Their solutions include probing technologies and machinery, as well as drilling equipment. For nearly 90 years, Carl Hamm has been recognised as a provider of superbly engineered products and topnotch technical expertise to the mining sector. Developed and made in Germany, their high-pressure (HP) connections and piping products prove their worth day in and day out in applications worldwide. They also offer a versatile range of quick couplings and other components which can be included as required to create the optimum solution for the specific requirements at hand. Without exception, all of their HP piping and products must pass rigorous cold-water pressurisation and other quality control testing before leaving the plant.

Geotechnics solutions The high-quality geotechnics Carl Hamm test systems are acclaimed and used worldwide. They conduct soil sampling and provide research equipment for site investigation and old neglected deposits. Soil sampling up to the depth of 15 m can be done. For nearly 20 years Carl Hamm has successfully manufactured and sold geological probing and control systems. Due to their persistent research and development, appropriate production processes and market-oriented sales structures, they rank among Germany’s leading providers. Their high-quality products are used all over the world by engineering geologists, the construction sector, agricultural institutions, and institutes of higher education.

The following services are provided: • Well support material • Water sampling • Water, air and gas analytics • Sample receptacles • Soil analysis • Concrete, cement and asphalt analysis • Laboratory equipment • Surveying technologies

Being smooth means fewer snags and more space for wiring and cables. To find out how Carl Hamm in South Africa can help you, contact Chris Munnick at +27 (0)72- 256-0926, +27 (0)10-900-2005, chris@carl-hamm.co.za, or visit www.carl-hamm.co.za.
