Wellman 120 is a permanent alternative to traditional materials such as steel, fibreglass, PVC and polyethylene in water wells with electric submersible pumps.
BEST OPTION FOR WELLS WITH ELECTRIC SUBMERSIBLE PUMPS
Designed as a permanent alternative to traditional materials such as steel, fibreglass, PVC and polyethylene in water wells with electric submersible pump
- Rapid installation & retrieval.
- Low maintenance.
- Superior hydraulic performance.
- Easy to store & transport.
FLEXIBLE RISING MAIN
Is designed as a permanent alternative to traditional materials such as steel, fibreglass, PVC and polyethylene in water wells with electric submersible pumps.
Suitable for pump settings up to 120 metres, Wellman 120 is used in applications such as domestic, light industrial, remote areas and well test pumping.
A one-piece composite, giving excellent stability and removing any risk of delamination.
A reinforced cable attachment strap prevents the power cable stretching the strap which can lead to full detachment.
• Domestic systems
• Light industrial applications
• Environmental monitoring
• Well testing
• Golf Courses

RAPID INSTALLATION & RETRIEVAL OF THE SUBMERSIBLE PUMP
Supplied in a single length to the required pump setting, there are no flanges or joints, except at the pump and headworks. Depending on the specific conditions, installation may be carried out by hand, crane or vehicle allowing for rapid restoration of service in the event of routine maintenance or pump failure.
All hose materials used result in zero corrosion and no scale build up. The high-grade polyurethane lining and cover material is resistant to hydrocarbon fuels, certain chemicals, ozone and UV, abrasion and microbial attack.
The textile reinforcement is designed to swell under operating conditions up to 15%. This feature gives a nominal increase in riser diameter, reducing friction loss and improving hydraulic performance.
Wellman has a small storage footprint compared to rigid pipe, allowing transportation by smaller vehicles and require less manpower. In certain circumstances, Wellman 120 can be installed by hand. Particularly useful when installation is required in remote locations with poor access.
Designed for use with pump settings up to 120 metres, our unique manufacturing process allows drums of up to 1,000 metres in a single length to optimize efficiencies for stocking distributors.
Wellman 120 is manufactured using -Through-the-Weave- technology, where the high grade polyurethane lining and cover are formed in a single process to provide a tough composite riser. The textile reinforcement is designed to support the weight of the submersible pump, the column of water, the power cable and the riser itself, with a minimum 2.5:1 safety factor.
Additionally, torque on pump start-up is accommodated without damage to the riser. The Mandals company also manufactures the textile weaving looms used by all major hose manufacturers throughout the world so their understanding of textile design and technology is unparalleled.
