Choosing the right bore pump is essential for maintaining a reliable water supply on your property. Whether you're supplying water to your home, irrigating crops, watering livestock or maintaining a rural property, the right pump can make a significant difference to water pressure, energy efficiency and long-term running costs.
With different bore depths, flow rates and pump types available, finding the right solution can feel complicated. This guide explains what to consider when choosing a bore pump and how to select a suitable Grundfos pump for your water requirements.
1. Understand Your Bore Depth and Water Level
Before selecting a bore pump, it's important to understand the characteristics of your bore.
Two key measurements are the static water level, which is the depth of the water when the pump isn't operating, and the pumping water level, which is the depth the water drops to while the pump is running.
A deeper pumping water level generally requires more pressure from the pump to lift water to the surface.
You should also consider the bore's internal diameter to ensure the pump can be installed safely and operate correctly.
2. Calculate How Much Water You Need
Different properties have different water requirements. A household supplying bathrooms, kitchens and laundry facilities will have different demands from a farm using water for livestock or irrigation.
Consider how many outlets may operate simultaneously, how much water you need during peak periods and whether you're filling a storage tank or supplying water directly to a pressurised system.
Flow rate is commonly measured in litres per minute (L/min) or cubic metres per hour (m³/h). Your pump should meet your required flow rate without exceeding the sustainable yield of your bore.
3. Choose the Right Pump Pressure
Flow rate alone isn't enough to select the correct bore pump. You also need to consider the total dynamic head (TDH), which represents the pressure the pump must overcome.
This includes the vertical lift from the pumping water level, the elevation difference to the delivery point, friction losses through pipes and fittings, and any additional pressure required at the outlet.
Choosing a pump based only on bore depth can result in poor water pressure or inefficient operation. Matching both flow rate and total dynamic head to the pump's performance curve is essential.
4. Consider a Grundfos Submersible Bore Pump
Grundfos offers submersible bore pump solutions designed for different residential, agricultural and commercial water supply applications.
Two product ranges worth considering are:
-
Grundfos SQ and SQE: Compact submersible pumps commonly used for domestic water supply, irrigation and pressure-controlled applications, subject to model suitability.
-
Grundfos SP: Stainless steel submersible bore pumps available across a broader range of capacities for agricultural, commercial and demanding water supply installations.
The best choice depends on your bore dimensions, water quality, required flow rate, operating pressure and power supply.
5. Check Your Power Supply and Energy Efficiency
Before purchasing a bore pump, confirm the type of electrical supply available at your property.
Some installations require single-phase power, while others may use three-phase systems. Solar-powered pumping may also be suitable for remote properties, depending on the system design.
A correctly sized pump can reduce unnecessary electricity consumption and minimise wear caused by inefficient operating conditions.
6. Consider Water Quality and Long-Term Reliability
Bore water can contain minerals, sediment and other substances that affect pump performance.
Water quality should be assessed before choosing a pump, particularly where sand, corrosion or mineral deposits may be an issue.
Selecting appropriate pump materials and installing suitable protection equipment can help extend service life and reduce maintenance requirements.
7. Get Expert Advice Before Purchasing
Selecting the wrong bore pump can lead to inadequate pressure, excessive energy use and premature equipment failure.
Before ordering, gather your bore depth, pumping water level, bore diameter, available power supply, required flow rate and intended water use.
