A submersible pump is a sealed water pump designed to operate fully submerged inside a borehole. Unlike surface pumps, submersible pumps push water upward rather than pulling it, making them far more efficient for deep water extraction.
These pumps are commonly used for irrigation, livestock watering, residential supply, and industrial water systems across Western Australia.
WA boreholes face conditions that many pump systems are not designed for. These include high mineral content, sandy water, fluctuating water tables, and extreme temperatures.
Using the wrong pump type often results in overheating motors, reduced pressure output, and frequent seal failures. Selecting a borehole-specific submersible pump ensures reliability, efficiency, and long service life in regional and remote WA environments.
Not all pumps perform the same underground. Understanding each option prevents costly mistakes.
The submersible pump is the most common borehole solution. It is ideal for deep bores and delivers consistent water flow with minimal energy loss. These pumps are widely used for domestic, agricultural, and commercial water supply.
A pressure pump is often paired with a submersible pump to regulate water pressure at the surface. While it is not installed inside the bore, it plays a critical role in maintaining steady pressure across irrigation systems and buildings.
A progressive cavity pump is the best choice for boreholes with sandy, silty, or abrasive water. It uses a rotating screw mechanism that handles solids better than standard impeller pumps. These pumps are common in agricultural and mining applications across WA.
A sump pump is not designed for borehole extraction but is sometimes confused with submersible pumps. Sump pumps are used for drainage and groundwater removal near structures. They are not suitable for deep bore water supply and should never be used as a bore pump.
Choosing the right pump starts with bore data. Depth, static water level, yield, and water quality determine pump size and type.
Flow rate requirements must match usage. Residential systems need stable pressure, while irrigation and livestock systems prioritise volume. Selecting an undersized pump leads to pressure issues. Oversizing wastes energy and increases wear.
Material quality matters in WA. Stainless steel construction offers better corrosion resistance, especially in coastal and mineral-rich regions. Motor cooling design is critical for long run times in hot climates.
Many pump failures are preventable. Running a pump dry damages seals and motors. Poor filtration allows sand to destroy impellers. Incorrect electrical protection leads to overheating.
Using the correct pump type, installing proper control systems, and scheduling routine inspections dramatically reduce failures. Borehole pumps are not fit-and-forget equipment in WA conditions.
Professional installation ensures correct depth placement and cable protection. Incorrect installation shortens pump lifespan regardless of brand quality.
Maintenance should include checking pressure levels, inspecting control panels, and monitoring flow consistency. Early signs of failure include pressure drops, unusual noise, and fluctuating water output.
Preventive maintenance costs far less than emergency pump replacement.
What is the best submersible pump for boreholes in Western Australia
The best option depends on bore depth, water quality, and usage. For sandy bores, a progressive cavity pump performs better. For clean water, a stainless steel submersible pump is ideal.
Can a sump pump be used for a borehole
No. A sump pump is designed for shallow drainage, not deep water extraction. Using one in a borehole will lead to failure.
Do I need a pressure pump with a submersible pump
Yes in most residential and commercial systems. A pressure pump ensures stable water pressure across taps and irrigation lines.
How long does a borehole submersible pump last
With correct sizing and maintenance, a quality submersible pump can last 7 to 15 years in WA conditions.
What causes borehole pumps to fail early
Common causes include dry running, sand ingress, poor electrical protection, and incorrect pump selection.
