Submersible pumps are used across several industries, including water supply and distribution, construction, irrigation, wastewater treatment, oil, mining, agriculture, and more. They are preferred over centrifugal pumps because they help prevent cavitation, which is the main cause of damage in pumps. Submerged in water, submersible pumps push water to the surface quietly and safely
Submersible pumps have plenty of applications beyond industries and can also be used in small-scale residential projects. For example, you can use them to transfer water from deep wells and boreholes into storage tanks. You can also use submersible pumps to drain the water out if your home got flooded.
Once you’ve decided that a submersible pump is right for you, be sure to get yours from a reputable brand such as Jung Pumpen. This website is the sole supplier of Jung Pumpen pumps in the UK. They can also help you pick the right pump for home or industrial use.
Submersible water pumps are designed to be fully submerged in the fluid they are pumping. This allows them to operate efficiently without the need for priming. These pumps are used for various applications such as draining water, pumping water for drinking, irrigation or firefighting, and handling dirty water, slurries, or solids. There are models tailored for specific applications such as sewage treatment plants, seawater handling, and oil wells. Submersible pumps are highly advantageous because they do not require priming, are efficient due to water pressure pushing the water into the pump, and are quieter than pumps that operate above water. However, they must be fully submerged to function properly. If used out of water, they can overheat and damage the motor. These pumps are available in various models, such as single-stage pumps for home and light industrial use, and multiple-stage pumps for oil wells and water wells. They are also available with different impeller designs to handle specific types of fluids, such as those containing sand or other solids.
The submersible pump is used for draining water: for example, for reducing groundwater, pumping groundwater to be used as drinking or fire-fighting water, pumping dirty water, and draining wastewater.
If you have a swimming pool in your garden, this pump can be used for draining it if you want to reduce the water level or add clean water. If you are dealing with a flooded cellar, for example due to leakage, this pump can be used to drain the water.
The pump has a suction grid fitted to the bottom, through which water is drawn directly into the pump. The water is then transferred through the pump body to the delivery connection, through which the water can leave the pump. The delivery connection has a discharge hose or tube attached to it so that the water can be drained. The pump can be partly or completely immersed in water because it cools itself with the water it pumps. As a result, running dry can damage a submersible pump. This is why no submersible pump is capable of draining a surface completely dry in automatic mode (using a float), but some models are able to do so in manual mode. They drain to the point that just a few drops need to be mopped up. In principle, it is the most simple model in this category of water pumps. The hose is screwed onto the pump, the plug is inserted into the socket, and the pump does its job, or starts as soon as the float is activated.
There are different types of submersible pumps that can easily be tailored to the type of water/fluids needing to be pumped. Situations may arise that make draining water difficult, but there is usually a solution. For example, if a space needs to be drained completely dry, a submersible puddle pump is perfect for the job. Sometimes these spaces are very limited in terms of size, and therefore special internal floats/float switches have been developed so that the pump can continue operating automatically. These pumps have also been kept small in size so that they can be placed in a sump pit.
Another specific model in this range is the FEKA submersible pump. They are often used on farms for draining faecal matter, and there are many additional solutions for problems involving these situations. Because faecal matter contains caustic substances that may affect the pump and its rubber seals, these special submersible pumps are fully protected against these substances.
If you are looking for a submersible pump and want to make sure it is worth the investment, the following four tips may come in handy for determining the best model:
Tip 1: Check pump capacity. One pump may have a capacity of 7,500 litres per hour, while another one is able to process 18,000 litres per hour. Ask yourself what capacity you require, and look for a pump with this capacity.
Tip 2: Check the delivery head. The delivery head refers to the maximum height at which a pump can raise water. Some pumps have a delivery head of eight metres, while others have one of five metres. Check again what you need, and find a pump that meets your requirements.
Tip 3: Consider whether the pump needs to switch on and off automatically. This is done with a float. In automatic mode, pumps are not capable of pumping a surface completely dry. This is only possible in manual mode, and you need to switch it off in time.
Tip 4: Check which accessories are supplied with the pump. Some pumps are more user friendly than others, simply because they come with more accessories. If you consider ease of handling very important, we advise you to check which accessories are standard with the pump.
With the above tips in mind, you will definitely find the submersible pump most suitable for your needs.
