What Is Borehole Pump?
A Borehole Pump Is one that is placed in a water source, such as a groundwater well, from where it is able to pump water under very high pressure through the delivery outlet. This model pump is better suited for this job than the self-priming ones (such as garden/booster pumps), which means it is ideal to be used at a water depth that exceeds eight metres. A borehole pump is characterised by its long, narrow pipe, which is suitable for wells/boreholes with a minimum diameter of 4” (10 cm).
What Types Of Pump Are Used In Boreholes?
Submersible borehole pumps are a type of submersible pump. They are centrifugal pumps driven by a submersible motor. As they usually draw in the fluid directly without a suction line, they must constantly be submerged in the fluid handled.
How Deep Should A Borehole Pump Be?
Put simply the borehole should be as deep as is required to reach the aquifer (water bearing rock). The average depth of a borehole is between 80m and 120m but this can be less as well as significantly more.
How Long Can A Borehole Pump Run For?
The best answer is that a borehole pump should last at least eight to ten years. A modern borehole pump that has been correctly installed by certified professionals, like Jordan Pumps, should last for many years.
Can A Borehole Pump Run Continuously?
Submersible pumps can run continuesly for years together without any interruption. They don’t need any rest.
What To Know Before Drilling A Borehole?
Ensure that there are no electrical cables, sewage or water pipes buried below ground where the drilling will take place. Drilling should also take place a safe distance away from buildings, substations and other surface infrastructure. The safe distance will largely be based on site-specific conditions.
Buying a Borehole Pump?
A borehole pump is set up in a water well, and is used mainly to spray/irrigate a garden or lawn as well as, for example, to recycle rainwater. It is used for pumping water from a depth of a few dozen metres, which can then be used to irrigate your garden or for other purposes in and around the house.
Installing a Borehole Pump
The borehole pump is immersed just above the bottom of the water well, where it immediately draws in groundwater or rainwater. The greatest advantage is that a borehole pump is practically silent, unlike garden and booster pumps, because it is submerged in the water, which absorbs most of the noise. A disadvantage may be that borehole pumps are generally more expensive than other water pump models. However, if you are willing to invest a bit more to get a practically silent pump, a borehole pump is definitely the one to choose.
Re-Use Stored Rainwater
More and more people install a water well in their garden to collect rainwater, which is then filtered and can be reused. Rainwater is a natural way of irrigating without having to use drinking water, which will save you a great deal of money on a yearly basis. The pump will pay for itself in no time. We have a whole selection of borehole pumps in different price ranges, which are generally offered at competitive prices.
Which Borehole Pump?
Now that you know what a borehole pump is, and how it works, you can choose one of the models from our collection. In terms of what you need to be aware of when choosing a borehole pump, this depends entirely on your situation. It is important to know at what depth the pump will be hung, and how wide the passage is to and in the well. If you have this information at hand, choosing the right model will be much easier.
How Does A Borehole Pump Work?
Borehole pumps consist of three parts: the motor housing, the pump body, and the suction grid. The motor housing steers the pump body, allowing it to pump water, which enters it through the suction grid. The pump body is fitted with several impellers. The more impellers, the higher the pressure and flow rate it can provide. After passing through the impellers, the water will exit the pump through the delivery outlet. A hose/pipe can be connected to the delivery outlet, through which water can be pumped under high pressure.
The selection of a borehole pump depends on your situation, and is based on the following variables: How wide is the passage to/in the well? How deep will the pump be immersed? How much flow rate and pressure do you require? For answers, please refer to our pump configurator (blue bar), and we will then suggest one or several borehole pumps that may be suitable.
Borehole Pump With Booster;
A borehole pump with booster, also known as an underwater booster pump, is used mainly in rainwater harvesting systems to recycle water: for example, to flush a toilet or to supply water to a washbasin, a washing machine, or a dishwasher. In these situations, this type of pump is the most practical solution because it can be installed ‘invisibly’: namely, in the well. This will save a great deal of space. In addition, the pump’s noise level will be very low because it is positioned under water. Furthermore, the borehole pump with booster is activated/deactivated automatically depending on the water requirement. When a washbasin tap is opened, the borehole pump switches on automatically, and switches off when it is closed again. We supply the following borehole pumps: the DAB Divertron series, the Tallas D-ESUB, the DAB Kit Pulsar Dry, and the EJ6 Plus.
Borehole Pump With Speed Controller;
Ideally, a borehole pump with speed controller is used for larger irrigation systems. The speed controller (e.g. the DAB Active Driver) controls the pump, allowing it to increase and decrease its speed gradually, until the required RPM has been reached. This is particularly important with regard to the larger irrigation systems, because without a speed controller the pump would consume several kilowatts all at once, which would significantly reduce its lifespan. We therefore advise that you always equip heavier borehole pumps with a speed controller. Furthermore, this combination pump is also ideal for irrigation with different sprinkler groups, because it is able to provide each group with a pre-set pressure level, and will increase and decrease its RPM speed automatically to achieve this.
