Wellmaster Horse

overview

Wellmaster hoses are used to pump groundwater from wells and can also supply drinking water. They can also be used as an alternative to vertical piping. Their high tensile strength allows for the suspension of a submersible pump directly from the hose, saving space within the well. They are also highly resistant to deterioration, reducing maintenance costs. (Please contact us if the hose contains corrosive substances.)
Furthermore, thanks to quality control that complies with international standards, this hose is also capable of supplying drinking water.

Hose features

  1. Seamless, single-piece construction

    Each unit can be manufactured up to a maximum length of 200m, enabling long-distance installation. During pump maintenance, there is no need for disassembly/reconnection work like with riser piping, significantly reducing time and labor.
    Additionally, a strap is equipped on the side of the hose to secure the pump's power cable, allowing for smooth operation without the cable getting tangled.

  2. Robust structure

    ANGUS's unique "Through-the-Weave" manufacturing method integrates a highly elastic polyester jacket with a tough yet flexible polyurethane resin. This seamless, one-piece structure achieves extremely high tensile strength, safely supporting not only the weight of the hose itself and the lifting load, but also the weight of the submersible pump. While withstanding very large loads, the vertical elongation is kept to 2%. This robust structure allows for the safe delivery of water at extremely high pressures, with a maximum recommended continuous head of 150 to 400m.
    Furthermore, it is highly resistant to twisting and torsion, and can absorb vibrations from submersible pumps.

  3. High safety

    Manufactured in accordance with the BS EN ISO 9001:2000 quality management system, materials, components, and finished products are rigorously inspected and stored to ensure reliability. The water quality is maintained at the same level as bottled water, making it suitable for dispensing drinking water.
    Furthermore, it complies with the following safety and quality standards/specifications and is used by water utilities and drinking water manufacturers worldwide.

    • WRAS: British drinking water
    • NSF International: The International Foundation for Health Sciences
    • DVGW: German Water Association
    • AFNOR: French Standards Association
    • AS 4020: Australian standard
  4. Lightweight/Compact

    Conventional rigid piping requires ample storage space and heavy machinery for movement due to its weight, but Wellmaster hoses eliminate both of these requirements. The Wellmaster hose 250, with a diameter of 2 inches, weighs only 570g per meter and can be wound onto a reel, allowing for work in limited spaces without the need for heavy machinery.
