Factors in safe water abstraction installations

Selecting components based purely on a pressure rating is very dangerous and you could possibly lose your equipment. Carl Hamm considers every variable. by Jaco Cilliers

Buying the cheapest products is often the most expensive option. Many companies offer cheap products that might end up costing you your borehole. Chris Munnick, CEO of Carl Hamm SA, explains: “People only take the pressure into consideration when choosing the pipes that they attach to their borehole pump. This can be fatal for the borehole. If the weight of the water, pipe, cable, pump, and motor

are not also considered, the coupling can fail, which means that all your expensive equipment will drop into the borehole.” This is why Carl Hamm provides a unique water abstraction solution to every client. They ensure that all the variables are taken into consideration and then multiply the results by two to three times to ensure safety.

For your own risk management the supplier must sign off the design incorporating: • Pump shut valve pressure • Pump and motor weight • Cable weight • Pipe and coupler weight • Water weight • Surge • Safety factor between 2 and 3 One of the reasons for Carl Hamm’s success is the ZSM connection coupling that they use, along with the quality of the pipes that can withstand pressures of up to 150 bar.

During the development of the ZSM coupling that joins the pipes, every stress point is identified and thoroughly tested to minimise accidental

failures. Carl Hamm specialises in industrial applications as well, and installs borehole water abstraction systems varying between 50 mm and 1 400 mm in size.
