Description
Flexibore is a flexible style riser pipe used for the installation of Submersible Pumps. The Hose is produced by integrating thermoplastic polyurethane into a woven textile fabric of high tenacity polyester. This process gives the hose flexibility while supporting the weight of a submersible pump.

Typical Applications 
These include mine site de-watering, domestic and municipal water supply, test pumping, rural and industrial water bores and similar ground water projects. 

Easy Installation 
On site Flexibore is attached to the pump with the patented couplings. The pump, with hose and cables attached, is lowered into the bore by hand or using either a simple rolling wheel or a crane.

Compatibility 
Flexibore will suit many water bore applications and is compatible with most submersible pumps. The sizes range from 40mm to 200mm internal diameter and depths of up to 250m.

Benefits and Cost Saving Features 
  •  Quick and easy installation and retrieval 
  •  No internal scaling 
  •  Totally corrosion resistant 
  •  Reduced head losses and improved flow rates due to swelling under pressure 
  •  Reduced transport costs due to light weight and easy handling 
  •  Custom lengths made to order 
  •  Potable water approved: AS 4020 
  •  All hydrostatically tested 
General Application 
Flexibore has been specifically designed to replace rigid riser pipes such as steel which is subject to rust and encrustations. This internal scaling reduces flow rates and pump efficiency. Other risers such as fiberglass and polypipe can be brittle or kink and are easily damaged. They are also generally heavier and hard to handle.

Transportable 
With its continuous length, the hose can be installed with less time and labour than rigid systems, this includes poly pipe. The same advantages apply to pump retrieval.
