GOLLMER & HUMMEL dewatering hoses are designed for draining mines combined with mobile pumps and suitable as a compact solution for this demanding task that a rigid pipeline cannot fulfill: Flexible GH flat hoses can be quickly and easily rolled out and laid over long distances using a hose reel system and reeled up after use to save space. Short lengths can be uncoiled and recoiled with little manpower.
We know this challenge in mining and design GH hoses for draining as durable and resilient flat hoses: TPU (thermoplastic polyurethane) is pressed (extruded) through the tightly circular woven polyester. During this step, we make sure that the polyester fabric is positioned centered in the TPU during extrusion - the TPU inner layer and TPU outer layer are of uniform thickness.
In open pit well drilling and dewatering wells, water is brought to the surface by a riser pipe and pumps. In open pit mining, well drilling prevents the mining site from filling with water. If the well water has a high mineral content, corrosion will occur in normal riser pipes where the individual sections are connected to each other. Here, too, the aforementioned advantages of a flexible hose solution come into play!
When developing wells from which drinking water is pumped, GH drinking water flat hoses serve as flexible risers! They are also flexible, safe for users, easy to lay and roll up.
In addition, thanks to special drinking water TPU that is evenly extruded through the polyester fabric insert, they protect water quality from microbes and contamination.

We normalize our PU hoses after extrusion. In other words, actual hose usage is simulated. Consequently, GH PU hoses are smoother and more flexible to handle and can be wound up small.
The hose is endowed with its absolute resistance during production: when extruding PU or rubber hoses, we take meticulous care to ensure that the jacket lining is centered in the hose body. This way, the inner and outer protective layers are uniformly thick – the jacket layer is the well-protected core. Ready for a strong hose performance!
