Talking About Ash Slurry!

As long-time manufacturers of slurry pumps, Darling Pumps realizes that the topic of ash slurry is a little complex. However, whether we talk about slurry pumps, or submersible dewatering pumps or any water pumps for that matter, no function of them is impossible to understand.

Therefore, in an attempt to help the people who are feeling a little lost when it comes to the subject of ash slurry, this blog explains a little about the same.

For starters, you should understand that in thermal plants, coal is used as fuel in order to generate electricity. Burning of coal leads to the generation of ash. This generated ash needs to be carefully disposed off from the thermal power plant.

Following are the types of ash generated in a thermal power plant:

1. Fly Ash- Out of the total of ash generated in thermal power plants, around 80% is fly ash. This ash is in the form of really fine particles. 

2. Bottom Ash- This refers to the ash that is being generated below the furnace of the thermal power plant. The bottom ash is about 20% of the total ash generated. Due to its coarse nature, bottom ash needs to be further crushed before it can go into the ash handling system.  

If you lost us at ‘the ash handling system’ then don’t worry, here’s a little bit which explains to you, what that refers to. 

The ash handling system is also known as the ash handling plant. This is used in thermal power plants to cool down the generated ash and bring it down to a manageable temperature.  Further, it is transferred to a storage facility or a disposal area and used in other industries.

The ash from the bottom ash handling system, when mixed with water in bottom ash silo, forms slurry. This new formed slurry is then transported to ash disposal area. From here the slurry is further pump out through slurry handling pump.

Although in doing this slurry pumps suffer through a lot of wear and tear. This wear and tear lead to its own set of problems, like the following:

1. Increase in maintenance and repair costs

2. Improper quality of pumping 

3. Replacement costs 

4. More time to get the job done right

Therefore, one should always focus on getting the right kind of slurry pumps, when it comes to dealing with something as complex as ash slurry.

Why the Need of Submersible Dewatering Pumps?

In this real world of competitiveness, time has truly taken over the value of money. Therefore, in these days, the construction sites have no time for any kind delays due to unwanted water. This fact paws way for the manufacturer who has high reliability quotient to this & has complete pumping solutions in his range.

This brings us to submersible dewatering pumps. A manufacturer who provides a great range of such pumps would know to make them for pumping out water in large volumes, regular dewatering, pumping out industrial waters, heavy duty pumping dewatering etc.

The high head submersible pumps are very critical for every Micro tunneling projects, Water supply projects, Underground pits, Big construction sites as well for mining sites. They can be used for pumping dirty water as well as for pumping this dirty / abrasive water to greater & higher distances.  Additionally, they come in very handy when the drainage needs to be done at narrow spaces. Being portable they can be moved to various locations as well.

This tells us that whether someone works in mining, construction, or tunneling the high head submersible pumps become their best insurance against any kind of water related downtime that they might face.

If you go for a reliable manufacturer, who promises to provide good quality water pumps, then they you can opt for some unique add-ons like pumps suitable to pump out hot temperature liquids as well as saline water.

Thus, the need of submersible dewatering pumps comes on various occasion. Apart from the wide range of applications that it serves, it also assists otherwise. For example, the don’t really require spending too much of energy in moving water into the pump. This is why they are said to be pretty efficient. In the process, the water pressure’s role is to push the water into a submersible pump. This is how it saves a lot of the water pump’s energy. In fact, it is seen that some submersible pumps are able to easily handle solids up to size of 25 mm as well. However, some are better for only liquids. These water pumps are quiet as well as smooth in executing their functions.

Therefore, the need of submersible dewatering pumps, becomes inevitable to people at work sites. However, one must always remember that the product quality plays a big role in the whole process!  

Choosing Pumps for Jobsite Dewatering

Whether we talk about solid handling submersible pumps or dewatering submersible pumps in India, we always have to know how we can wisely choose a pump. As the renowned providers of solid handling submersible pumps, we are here to help you with the same. As it is only when you know how to choose a pump, that you will be able to finally use it appropriately and get the required results for your benefit.

Following we have put down a few points that you should go through, before making the important decision of choosing a pump for jobsite dewatering.Pump Application Checklist When we talk about the first step that is involved in developing a jobsite dewatering plan, it is to identify the required capacity.Along with identifying that, you also need to analyze discharge head and suction lift at the site.

If you are wondering, what refers to the required capacity, it is the amount of fluid that is required to be moved and the rate at which it needs to be moved. This capacity is measured in gallons per min. However, suction lift refers to the vertical distance of suction which the pump has to overcome in order to bring the fluid into the pump. This distance gets measured from the top of the pumping fluid all the way to the height of the suction end of the pump.

When we talk about the discharge head, it refers to the vertical height of discharge pipe or hose. Once you have been successful in calculating these factors, it is possible to easily determine the appropriate pump that should be used for the application.

However, it is advised that before you select a pump for the job, you should carefully evaluate the site conditions and give an answer for the following questions.

 What has to be accomplished by the pump?

 What is the type of the liquid that requires to be pumped?

 How far would the fluid require to be pumped?

 At what rate will the liquid need to be moved?

 Will there be a need of any auxiliary equipment?

 Will noise be a problem?

 Where the pump would be placed?

 Where the liquid would be discharged?

 Will filtration be required by the application?

Once you analyze all of this, you are good to go. For the best dewatering submersible pumps in India, come to us at Darling Pumps.

Introducing SVT (Submersible Vertical Turbine) Pumps

In the last blog, we talked about vertical turbine pumps and their basics. We discussed various features of these pumps, what they are, their applications and their construction along with their limitations.

Although vertical turbine pumps are very popular for raw water pumping, but they comes with their own limitations like – they require dedicated pump house, are difficult to install, has limited operations during monsoon, prone to frequent maintenance post monsoon, high spares & maintenance cost, complicated & time consuming maintenance so on…

Add to this, at times Vertical turbine pumps cannot be used when they are needed the most i.e. summer time. As water level goes down normal VT pumps cannot be used & even if they are put to use somehow there is a huge risk of abnormal wear & tear if raw water has any sand content.'

So, what do the modern day engineers do?

Live with these limitations or opt for peace of mind….

The answer lies in “Darling Pumps” - who has introduced a new concept of -  Submersible Vertical Turbine (SVT pumps).

Darling - SVT Series pumps are equipped for turbid raw water pumping. They are an ideal replacement for conventional Vertical Turbine pumps & stand good where consistent & mass water supply is to be made. These pumps can be regularly seen in govt. water supply schemes / projects, Power generation plants etc.

The SVT (submersible vertical turbine) pumps do not only contain advanced features but also provide real value for money to its users. These pumps are ideal for various applications and situations.

If we go on exploring the advantages of the submersible vertical turbine pumps we discover that there are lots of them. Especially when we put up a direct comparison between the conventional vertical turbine pumps and the submersible vertical turbine series pumps, we understand why the latter is a better choice.

Therefore to make you understand this better, we will be sharing a detailed comparison between the two pumps, in the coming blogs.

The comparison would hold various basis including their cost, assembly, shaft, bearing, disassembly, civil work, routine maintenance, spares etc.

We think that the use of SVT (submersible vertical turbine) series pump would majorly benefit the users in terms of time, cost as well as ease of application.

All about Vertical Turbine Pumps

A Vertical Turbine Pump is also referred to as a deep well turbine pump. It is mixed flow type pump or a vertical axis centrifugal which comprises of stages. These stages accommodate stationary bowls that possess guide vanes. They also have rotating impellers.

When are they used?
When the pumping water level is below the limits of Vertical centrifugal pump that is the time when a Vertical Turbine Pump comes into use. They come with a higher initial cost and comparatively a difficult installation and repair process. When we talk about the pressure head developed, it depends on the speed at which the impeller is rotated along with the diameter of the impeller. However, when a single impeller is used to develop the pressure head it’s not so great. With the help of more stage or bowl assemblies, an additional head can be obtained.

The Way They are Constructed

A Vertical Turbine Pump is basically made up of three parts -

Discharge Column
The job of this part is to not only to connect the pump head and the bowl assembly but it is also to conduct water from the bowl assembly to the pump head.

Discharge Head
This part consists of the base. It is this base from which the shaft assembly, the bowl assembly, and the discharge column are suspended.

Pump Element
This element is made up of one or more stages or bowls. Each of the bowls that it is made up of consists of a diffuser and an impeller.

Limitations of the Vertical Turbine Pump

A Vertical Turbine Pump holds certain limitations to it. Here are few of them -

Maintenance
The vertical turbine pump requires quite a bit of attention when it comes to the regular maintenance of the pump. The pump also requires more spares to be maintained.

Disassembly
The vertical turbine pump is very difficult to dismantle. The pump also requires very expensive material handling equipment.

Assembly
The assembly process of a vertical turbine pump is as complicated as the process of disassembly. We hope the information above gave you a good idea about the vertical turbine pumps.

In the upcoming blog, we will discuss about Submersible vertical turbine pumps and how they overcome the limitations of vertical turbine pumps. To know more, call Darling Pumps at +91 99819 92838.

6 Benefits of using Submersible Pumps

Submersible pump, as the name suggests, can be completely submerged in the liquid that needs to be pumped. The ability to be immersed in water differentiates a submersible pump from a standard pump. Basically a centrifugal pump, submersible pumps push water to the surface due to the rotation of impeller. Depending on their application, submersible pumps can further be categorized into grinder submersible pumps, sewage pumps, waste water pumps and more. Darling Pumps is a pioneer in of submersible pumps industry in India. Through their innovative pumping solutions and quality product line, Darling Pumps has set a benchmark in the market.

 

 If you are considering whether to invest in a submersible pump or not, here are few advantages of submersible pumps that you should know –

 1. Priming – Submersible pumps are self-primed; you do not have to do priming separately before use. Thus, you do not have to spend time or money in preparing the equipment and get more time for completing your project.

 2. Repair Costs – As submersible pumps contain a water tight unit that keeps water out of the pump housing. This eliminates chances of leakage or electric shorts due to live wire. Thus, repair time and costs are reduced considerably. 

 3. Efficiency – Submersible pumps are placed at the point where fluid meets the pump so efforts required for pumping the liquid are less.  

 4. Convenience – Submersible pumps are light in weight compared to other types of pumps. They are portable, easy to move around and install.

 5. Variety – There is a wide variety of submersible pumps available in the market. From pressure sewage pumps to septic tank pumps, you can easily find a submersible pump that suits your application. 

 6. Insulated Power Cords – Submersible pumps are usually placed under water or fluid. So they come with long and insulated power cords.
