Flexibore® 120 is the lightweight, flexible riser hose engineered for mine operators, farmers, and contractors who need efficient and reliable bore water pumping up to 120 metres. Its unique ability to dilate under pressure improves hydraulic performance and prevents iron bacteria build-up, ensuring long-term efficiency. Unlike rigid poly pipe, it installs quickly, reduces manual handling risks, and delivers a low-maintenance, Australian-made solution for safe, productive pumping.

Flexibore systems are intended for upstream raw water transfer only, and it is assumed that suitable filtration and treatment are installed prior to connection to regulated potable water plumbing systems.
There are 3 recommended methods for safely installing pumps with Flexibore® : vehicle assisted, crane assisted, and hand assisted. The method chosen will depend on the bore depth, pump weight and access space.
Flexibore® couplings are designed to be fitted onto the hose during installation. Once the coupling has been attached to the pump, the hose is pushed onto the coupling tail; 2x 3-piece clamp sets are then securely fastened around the hose using an Allen key.
There are 2 methods to secure the power cable to the hose: Crusader Hose-approved heavy-duty cable ties & FlexiStraps.
As long as the total weight of the pump and cable falls within the safety margin of the max. tensile load, then no safety cable is required. If the total weight is higher than the recommended max. tensile load, please contact us to discuss safety cable usage.
