Groundwater pumping system

overview

Conventional groundwater pumping operations involve connecting multiple pipes and suspending them vertically. Furthermore, maintenance requires disassembling the long pipes, lifting each one individually, and then reinstalling them, which poses a significant burden.

The solution to these challenges is a "groundwater pumping system" that utilizes the "Wellmaster" manufactured by Angus, a British company.
The "Wellmaster" has a robust structure and tensile strength that can withstand the weight of the hose and the pump, allowing it to be connected to the discharge end of a submersible pump and suspended directly. Compared to conventional piping, raising and lowering the hose during maintenance is much easier, resulting in significant reductions in time and cost.
Its reliability is high, and in Australia, which suffers from chronic water shortages, orders have flooded in, resulting in a proven track record of widespread adoption, with manufacturing plants operating at full capacity.
Furthermore, because it possesses sufficient tensile strength to withstand the weight of the hose itself and the water, it can be used not only for wells but also as a replacement for vertical piping.

In times of disaster, it also functions as a water supply line from the ground to the water tank on the roof.
"Wellmaster" is a hose specifically developed for wells, and it can serve the dual purpose of "suspending a submersible pump" and "discharge piping."

Features

01

ANGUS"Wellmaster Horse"

Compared to installation and maintenance using conventional piping, it can be manufactured up to 200m in length, significantly reducing work time and labor. Furthermore, it is highly resistant to twisting and bending, absorbs vibrations unique to submersible pumps, and boasts excellent durability, weather resistance, and abrasion resistance, allowing for long-term, maintenance-free use.

02

Streamlining maintenance

Using a dedicated mine entrance roller, the pump and hose can be easily lifted. The connectors are designed to withstand vertical loads, and the power cable securing straps on the side of the hose eliminate concerns about hose detachment or cable entanglement, thus reducing working time.

Excellent water delivery performance and cost-effectiveness

The hose's inner surface is extremely smooth, minimizing pressure loss due to its expansion characteristics during water transport. Because it can transport water more efficiently than conventional rigid piping, it contributes to improved energy efficiency.

04

Also suitable for drinking waterHigh safety

The inner material of the hose maintains the same quality as that of a PET bottle. It ensures clean water quality, making it safe to use for drawing drinking water.

Depending on the work environmentProposed installation plan

We will propose various installation options depending on the environment, such as the workspace.
