Wellmaster Layflat Hose
Often Imitated, Never Equalled
About us
Since its formation in the 1970s, Angus Flexible Pipelines has been at the forefront of layflat hose technology through continuous investment in research and development, carried out at the company’s Technical Centres of Excellence in the UK and Australia. With a range of flexible hose, Angus’s Wellmaster is recognised the world over as the premier flexible rising main for deep ground water extraction.
Angus Flexible Pipelines has third party accreditation to ISO 9001 Quality Management System and ISO 14001 Environmental Management. All raw materials, components and finished products are rigorously tested and inspected to ensure consistent reliability and performance.
Every metre of Wellmaster layflat hose is rigorously tested before it leaves our factory.
Why Wellmaster hose?
-
Long continuous lengths can be quickly deployed and retrieved using light duty trailers, flaking boxes or power-driven reels. High flexibility and kink resistance allows natural ground contours to be followed without putting stress on the pipeline and eliminates expensive path-cutting work. Fewer joints and faster connections mean reduced labour and equipment costs. A comprehensive range of handling equipment is available.Description text goes here
-
Lighter and more compact for economical storage. A standard pick-up truck may be used instead of a flat-bed truck or fork lift. This reduces transport costs and enables direct routes inaccessible to larger vehicles and cranes to be taken.Description text goes here
-
Superior hydraulic performance with lower pressure loss for efficient pumping. Swells in use up to 10% beyond uncharged diameter at maximum operating pressure enabling more fluid to be pumped.
-
Capable of operating continuously at high pumping pressures with minimal maintenance in even the harshest environments. Tough and durable with exceptional resistance to abrasion and cutting for use on a wide variety of ground conditions. Unsurpassed resistance to weathering. Suffers no corrosion or scaling. Resistant to heat, fuels, chemical, ultraviolet, ozone, weathering, hydrolysis and microbiological attack.
-
Maintenance and repair can be completed in a fraction of the time required for rigid pipe. This means lower labour and equipment costs in addition to reduced downtime.
Wellmaster hose v rigid pipe
Why layflat hose?
In many applications involving fluid transfer the use of rigid pipe introduces severe limitations which can be overcome by the use of layflat hoses. The speed of deployment and retrieval, the small storage foot print and the ability to adapt to changing topography are just a few examples.
Additionally, the reduction in the number of joints delivers environmental and cost saving benefits. The ability to install certain products without the use of cranes brings significant health and safety benefits.
Minera Yanacocha, Cajamarca, Peru
-
Minera Yanacocha is one of the largest and most significant mining operations in South America, located in Cajamarca, Peru. Specialising in gold extraction, the site operates at high altitude under challenging environmental conditions, requiring highly reliable and high-performance water management systems to ensure continuous operation.
-
Minera Yanacocha required a robust and efficient pumping system capable of operating at a depth of 400 metres, handling high flow rates of 70 to 85 litres per second. The demanding conditions of the mine posed operational risks, and the client needed a solution that would ensure minimal downtime, high reliability, and a long service life in a remote and harsh environment.
-
The client needed a flexible riser system offering:
High pressure resistance and long-term durability
Rapid installation and removal to minimise labour and downtime
Consistent performance at depth with high flow
A clear return on investment (ROI) through operational efficiency and reduced costs
The selected solution was Angus Flexible Pipelines’ Wellmaster 400 – 6”, providing:
Excellent strength-to-weight ratio
Corrosion resistance, essential in mining water applications
Fast deployment, reducing installation time and costs
A proven global track record in mining applications
-
Angus supplied and installed Wellmaster 400, 6-inch, at a depth of 400 metres.
This solution enabled Minera Yanacocha to pump between 70 and 85 litres per second efficiently and safely.Product: Wellmaster 400 – 6”
Installation depth: 400 metres
Flow rate: 70–85 l/s -
The installation fully met Minera Yanacocha’s objectives, delivering outstanding and reliable performance. The client highlighted the ease of installation, operational efficiency, and durability of the Wellmaster 400 system. Minera Yanacocha continues to use Wellmaster 400 (6”) and 4” variants across various sites and is now a repeat customer, trusting in the quality and long-term value of Angus products.
Minera Pucobre, Copiapó, Chile
-
Minera Pucobre, located in the city of Copiapó in northern Chile, is a well-established mining operation primarily focused on copper extraction. The site operates in an arid and demanding environment, where efficient and reliable water management is essential to maintain continuous operations.
-
The operation required a durable and effective pumping solution for a borehole presenting chemically aggressive conditions, with water characterised by high pH and elevated hardness. While high temperatures were not present, the combination of chemical factors posed significant risks to conventional pumping systems. The goal was to ensure efficient water extraction, with minimal installation time, low maintenance, and strong chemical resistance.
-
The client needed a solution that would deliver:
High chemical resistance to aggressive water conditions
Proven durability in harsh mining environments
Safe and rapid installation with minimal equipment
Hydraulic efficiency and long-term reliability
Reduced operational costs over time
The selected solution was Wellmaster 250 – 4”, offering:
Outstanding resistance to corrosion and elevated pH levels
Easy handling and quick deployment on-site
Consistent hydraulic performance under stress
A globally proven track record in similar mining applications
-
Angus supplied and installed Wellmaster 250, 4-inch, at a depth of 250 metres, allowing for a flow rate between 15 and 19 litres per second.
The system was installed successfully, operating reliably and efficiently under aggressive water conditions.Product: Wellmaster 250 – 4”
Installation depth: 250 metres
Flow rate: 15–19 l/s -
The solution fully met the operational goals of Minera Pucobre, proving to be efficient, reliable, and resistant under harsh conditions. The client expressed satisfaction with the system’s performance and ease of use, highlighting its reliability in a chemically aggressive environment. Minera Pucobre continues to use Wellmaster products and remains a repeat customer, placing their trust in the quality and performance of Angus Flexible Pipelines.
