Product Details

1 inch to 8 inch Layflat Submersible Pump Hose NSF61 approved

Welline is one type of through-the-weave polyurethane (PU) covered hoses which are made of PU materials approved according to NSF 61 standard.

Welline hoses shall be made from 100% high tenacity virgin synthetic yarn circular woven and completely, totally embedded in the PU compound, excellent protected against mechanical damage, forming a single homogenous construction without the use of any glues or adhesives of any type.

The structure of Welline ensure that exposure to seawater and contamination by most chemical substances, hydrocarbons, oils, alkalis, acids and greases must have no effect on the short or long term performance of Welline hose.

Features

A simpler, safer and more efficient way to install Submersible pumps. Offering greater cost savings and superior hydraulic performance advantages over Poly Pipe / PVC Pipe, Fiber Glass and Steel Riser Pipes.

Superior abrasion resistance

Extremely hardwearing and durable for long service life

Resistance to oil, fuel and a wide range of chemicals (see resistance table in technical appendix)

Resistance to weathering and ozone

Flexible, lightweight and good handling

Excellent cold flexibility

Advantages

Lightweight, layflat coilable construction
Easy to handle - reducing the time and cost involved when installing submersible pumps
Easy to store and transport
Free of maintenance on rising main
Resistant to corrosion and microbiological and internal scaling
Absorbs vibrations, rapid changes in pressure and unwanted noise from the installation
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 labour and cost savings
Long operational life with a 10 years warranty

Installation

■ Assembly hoses with HPHC BSP coupling
■ Swivel HPHC BSP coupling onto submersible pumps
■ Attach power cable using Welline Cable Straps
■ Hang Welline hoses and pumps
■ Lower Welline hoses and pumps into well
■ Assembly the other end of hoses onto HPHC BSP coupling
■ Swivel top HPHC BSP coupling onto Well Head Base
■ Fix Well Head Base
■ Install elbows, valve and other output pipes

For some large boreholes, vehicles and cranes are required to assist installation.
