Borehole Piping

The perfect way to access pure and natural underground water is to use a borehole. boreholes have a narrow shaft that is drilled vertically and horizontally into the ground so you can access water underground, this will probably be the purest water you have ever had.

A borehole is used as a water well and is completed by using vertical pipes and screening to keep the borehole from caving in.

Boreholes can be used for a variety of reasons, like the extraction of water, you can use it as a sprinkler system on your property.

Boreholes can be used to measure the temperature, or it can also act as an underground storage for unwanted substances. Boreholes prevent surface contaminations from entering the borehole and protects any installed pump from bringing in sand.  What is a borehole without borehole pipes?

Benefits of borehole pipes

In order to design a water pump, you should account for protective measures, things that will keep your pump running for longer, corrosion and age. PVC piping can ensure that this job will be done and will provide this kind of protection.

  • Corrosion resistant – PVC piping being made from certain and specific materials, it is completely corrosive resistant, making it perfect for borehole pumps which will provide the kind of environment where corrosion thrives.
  • Durable, liable and long-lasting – PVC piping is a long-lasting product, which is why it is used all over the world in buildings and most homes. PVC piping is resistant to wear and tear and other damages.
  • Simple to install – PVC is a very easy material to maintain and very easy to install, thus little tools will be needed to install your borehole piping.

borehole pump

A submersible pump is a mechanical device that serves multiple purposes and is one the most of the most extensively used automatic devices. A submersible pump , also known as a an electric submersible pump or sub pump , is a pump that can be fully submerged in water . The motor is hermetically sealed and close-coupled to the body of the pump.

Advantages

The main advantage of this type of pump is that it prevents pump cavitation , or the formation of an air bubble , a problem associated with a high elevation difference between pump and the fluid surface. Sub Pumps push the fluids to the surface as opposed to jet pumps having to pull fluids down. Thus making sub pumps more efficient than jet pumps because they don’t use a lot of energy moving water , water pressure pushes the water into a submersible pump which in turn saves a lot of the pumps energy. The pumps are also very quiet due to the fact that they are submerged under water , which also helps with cooling the motor down.

How it works

A submersible pump pushes water to the surface by converting rotary energy into kinetic energy and further converts to pressure energy. This takes place when water is pulled into the pump as an intake , where the rotations of the impeller push water through the diffuser and from there it goes to the surface.

Uses

Submersible pumps are used for used for many things. Single stage pumps are used for drainage , sewage pumping , general industrial pumping and slurry pumping. Multiple stage pumps are usually lowered down into a borehole and most typically used for residential , commercial , municipal and industrial water extraction.

Also whilst the pumps themselves aren’t very versatile , the selection definitely is. Some submersible pumps can easily handle solids , while some are better suited for liquids only.

Sewage pump

Side-channel pumps offer the best of both worlds in terms of water pumping solutions, operating somewhere in between displacement pumps and centrifugal ones. They offer a unique and safe way for the transfer of clean fluids, and are used for a wide range of applications across a number of industries. They offer a number of advantages when compared to pumps for other types of fluid control systems, offering enhanced safety, more effective flow properties, as well as reduced NPSH requirements.

Enhanced Safety through Self-Priming

When they are initially run, side-channel pumps function much in the way that displacement pumps do. As the side channels are filled with liquid, however, they start to collect liquid from the outer regions of the side-channels and impeller cells, which allows it to act like a centrifugal pump. This facilitates an important function, namely self-priming. This makes them much safer to use than other pumping solutions.

Gas Transport with Uninterrupted Fluid Flow

Some processes require pumps to evacuate gas at essential points, and this needs to happen without interrupting the liquid flow. Pulsed pressure build-ups in side-channel pumps create an internal multi-stage effect which facilitates gas transport without interrupting liquid flow. This stops the pump from being damaged as a result of dry running, which in other systems, tends to damage pump bearings.

Reduced NPSH Requirements

NPSH requirements describe the minimum pressure required at the suction port in order to keep it from cavitation. Side-channel pumps produce pulse pressure build ups that result in an internal multi-stage effect that lowers potential pump speeds. This is thanks to higher pump heads and slower pump speeds. This increases expected lifespans for these pumps, and also offers greater control over noise.

gravity sewer

While gravity sewer pumps have been a staple of homes and buildings all over the world, they are not necessarily the most effective solution for removing water-waste. They come with their own set of advantages, but when compared to more carefully designed, modern sewage pumps, they do leave a lot to be desired.

Sewage Pumps Save Money

Sewage pumps are designed to be dependable, and works by rejecting materials that are too hard to be broken down. This allows them to work without any undue pressure that may cause them to break-down or become ineffective as time goes on. This means that you will be spending less time and money on maintenance in the long-run.

Sewage Pumps are Environmentally Friendly

The right sewage pump works by reducing the amount of harmful chemicals in sewage water. These compounds, with more traditional gravity systems, will generally find their way into natural eco-systems, contaminating them, water and even food sources, where they can pose a risk to human, animal and plant life.

Installation is Simple

Sewage pumps are compact and designed to be installed with relative ease, even in tight spaces. Furthermore, installing them with the help of a technician (which is advised) is generally inexpensive.

Works with High Sewage Lines

In buildings and homes where high sewage-lines make it impossible for gravity pumps to push water-waste uphill, sewage pumps are actually essential for correct removal of waste products. Even when high sewage-lines are not a problem, sewage pumps allow water to be pumped sustainably and evenly.

Water Pump

When it comes to harnessing the resources around us, doing it in a fast and effective manner ensures that we get the best results and optimum functions for those resources. One way we can harness the resources around is through the use of borehole motors available in Johannesburg.

This is done is through the use of a long cylindrical pipe that is installed into the Earth’s surface. This pipe reaches a section of underground water that can then be used for personal or industrial use. Through the use of electrical water pumps, many methods of extractions can be utilised, all for different purposes. Take a look at what kind of water pumps are available.

Pump it

When it comes to extraction of water in a confined space there are certain factors that come into play; electric water pumps come in all shapes and sizes depending on the task at hand. A Zuwa pump is used mainly for personal use and external threats such as flooding due to rain or a burst pipe.

When an area at home has flooded a room or more, the use of a zuwa pump extracts the water thoroughly, until it is completely dry. If a carpet has been flooded, the use of a suction mat allows all water to be extracted. Through the use of rotating propeller, it causes air to be pulled very quickly from the entrance to the exit thus creating a high volume vortex affect.

No.2

When it comes to our personal time on the loo, we do not like speaking about what happens after the whoosh of the leaver. Unfortunately, sometimes it springs up on us when a pipe gives in. luckily through the use of a sewage pump it is just one big slurp and then there is no longer an issue. The sewage pumps work in the same rotary motion as the electrical water pumps, which allows for maximum suction power.

The help of videos and tutorials goes a long way to help enlighten anyone about what the capabilities are of these incredible extraction machines. With that being said, water extraction or similar removals need to be done by professionals.

Other Water Solutions   

Sometimes, water leakage may not be the problem, but looking for better ways to utilise water is a great solution nonetheless. South Africa is often affected by droughts and various water shortage problems have become an environmental problem for individuals and our country itself.

Installation of borehole motors in Johannesburg, offers families their own personal supply of water when droughts roll in, whilst affording advancements on the environmental whole with sustainable solutions.

A contribution

South Africa has a very high poverty rate, sitting at 55.5%. it is clear that the majority of the country does not receive basic human needs. One of the most important human needs include the supply of uncontaminated water. Through the help of borehole motors in Johannesburg, there is a chance to give every South African the basic human needs that they deserve.

German engineers and products that hail from Germany are almost indisputably considered to be the best in the world. But what is the rationalization behind this? This article will focus on 4 key points that prove that if you want something that is well engineered, as a rule German goods are likely to be top of their class.

How and why does Germany have such an impressive engineering culture?

A Reputation that Speaks for Itself
German engineering companies are world famous for their production capabilities. Examples can be found in the automobile world in brands such as Mercedes, Audi, Porsche and BMW – companies that are well respected and known all over the world. German engineers are also world leading innovators and have invented some of the most technologically advanced products the world has even seen. As a rule, people who buy German products are more than likely looking for cutting-edge technology or a highly special design that probably cannot be found anywhere else. This has allowed Germany to dominate many markets.
Investing in Innovation
Aspirin, magnetic tape, x-rays and the electron microscope were all invented in Germany by Germans? German ingenuity is based on very deep technical expertise, which allows even the smallest German firms to become market leaders in very narrow segments. Investments in research and development activities is a very serious matter, and the industry spends billions to advance its interests. German companies continue to improve and advance in sectors such as the chemical industry, medical engineering, electrical equipment industry, automotive industry, and mechanical engineering. By investing heavily in innovation, Germany has managed to keep ahead of the rest of the world and supply markets with distinctive and in-demand products.
High Quality Education
Germany’s engineering education system has a very well regarded reputation around the world. Germany’s system includes a combination of classroom and business, theory and practice, learning and working. It is embedded deeply within the society and has close ties with leading players in the industry. The cooperation between mainly private companies and public schools has made this system one of the most attractive in the entire world when it comes to engineering. Private companies often bear the costs of the training, and this in turn helps them to save significantly on recruitment costs as they are able to identify and hire the best talent as soon as they have completed the course. Internships and apprenticeships are offered even to high school students to encourage their interest in engineering courses from an early age.
Quality that Speaks for itself
Products such as German submersible pumps, as a rule, simply last longer. This is a point that is difficult to prove with statistics, but many will readily corroborate the fact that products that have a German origin generally enjoy longevity. This is likely due to a mixture of the three points discussed above.

Electric motor units perform a great amount of work in today’s times. They keep many different electronic devices working and running properly. Various types of electric motors are used to make our lives run smoother, however, they can cost a pretty penny to replace. Luckily, electric motor rewinding can be done in order to get your motor working again without the high price tag.
There are many factors and reasons to consider when deciding whether to have your motor rewound instead of purchasing a new one. Professional care is needed when rewinding an electric motor as it is delicate. Even a small error throughout the process could result in quite a loss. It is by no means a simple task to rewind a motor, it is best to have a professional take a look and handle the rewinding process. At Ernest Electro we have professionals who are happy to help rewind your electric motors.
How do you know electric motor rewinding is for you?
When a motor’s insulation is damaged or ruined, the electricity will begin to transfer from winding to winding which will cause excess heat and damage the motor. Power problems often also result in the motor being damaged. Ensuring you take care of the routine maintenance which includes rewinding when necessary is going to extend the life and the productivity of your electric motor.
When rewinding a motor, first the motor housing is removed in order to expose the windings. Then the wire from the tabs on the brush pads is carefully removed. The wind free coils then get cut from the motor. The insulation is inspected to ensure it is still in good shape, then the armature is rewound. The exact same winding pattern is recreated and the number of coils around each of the windings. The windings are then connected and the wires double checked to ensure that the tabs aren’t touching. Once all of the above is done, the motor housing is then reassembled.
To rewind an electric motor is very tedious and quite difficult. Unless you are experienced, having a professional in the field take on the task is the way to go. At Ernest Electro we specialize in the rewinding of many different electric motors. Visit our website on www.ernestee.co.za/ for more information.

The side channel pump is a niche product that is somewhere in between a centrifugal pump and a displacement pump. Initially, these types of liquid ring pumps we designed to pump gas, air and liquid mixtures. A side channel pump can be used for many different applications.
A side channel pump will generally have these following characteristics:
• Offer the ability to transport gas without any interruptions to the fluid flow or damage to the bearings.
• They have automatic self-priming capability
• Offers maximum power consumption that its highest head and lowest flow rate.
• Narrows columns (side channels) are not suitable for abrasive particles in the fluids.
• A very low suction head (NPSH) is required.
• A steep capacity-head (Q-H) curves ideal for pressure-dependent system regulation.
When the pump is started, it initially functions just like a displacement pump because of its self-priming capability, but once the side channels are filled with liquid, it will begin to operate like a centrifugal pump does. The centrifugal effect will then cause a collection of liquid in the outer region of the side channel and in the impeller cells, this forms the liquid ring that is necessary for the self-priming process. The inner region is where the gas builds up. A side channel pump is also able to operate as vacuum pump for a certain amount of time before the auxiliary liquid starts to heat up and then finally evaporates.
Besides the pumps self-priming capability, it has the added advantage of also being able to handle big gas flows with the liquid. In some processes, it’s essential that the pump can, as least temporarily, evacuate vapours and gasses from the process without the liquid flow being interrupted. The standard radial centrifugal pump has a very limited capacity to transport gas within the medium. Even with a lower gas content, the liquid flow can immediately damage or interrupt the pump bearings because of dry running.
The pressure build-up that is caused by the sum of the individual pulses during the liquid movement will create an internal multi-stage effect, even when there is only one impeller. A lower potential pump speed is possible because of higher pump heads thus helping to reduce the pump’s NPSH requirement compared to a high-speed pump. With a lower pump speed, you will have the additional advantage that part load performance, mechanical loads and noise can be controlled better and the pump’s expected service life is then generally increased.
