Long Length Well Riser Layflat Hoses Connecting with Heavy Pump Through the Weave Extracting Groundwater 8 Inch
Welline HP is made from extruded thermoplastic polyether based polyurethane (TPU) with excellent wear & tear properties and is approved by NSF 61 standard.
The reinforcement is made from circular woven filament polyester yarn. The extrusion through the weave production method gives a very strong bonding between cover and lining as well as firmly encapsulating the woven polyester.
Welline HP is chemical resistant, acid resistant, and corrosion resistant. These hoses are connected with submersible pump and are very easy to be installed and retrieved.
Advantage
►Lightweight, layflat coilable construction
►Easy to handle, reducing the time and cost involved when installing submersible pump
►Easy to store and transport
►Free of maintenance
►Resistant to corrosion and microbiological and internal scaling
►Self-supporting layflat riser
►Easily installed in irregular wells
►Higher water flow in narrow wells
►High safety margins in both tensile and hydraulic performance
►Compatible with all types of submersible pumps
►Rapid installation and retrieval methods resulting in substantial labor and cost savings
