What questions should be answered, before selecting sewage pumps?

When it comes to sewage pumps, everyone’s dream and necessity is to own a properly working one. This stands true especially for homeowners who have basement toilets. 

The role of sewage pumps is to lift flushable waste into a septic tank or the sewer line. There are many people who often go for replacing their water pump with the same model as before. Before making the decision, you should always ask yourself, how long should your pump last?

Similarly, when selecting the right sewage pumps for your needs, there are some questions that you should ask yourself! The following is a list of those questions, along with the answers to the same:

1. How much flow is required?

To know what type of flow rate is required, it’s important to know the number of users that would be feeding the sewage basin as well as the number of drains. If you want to know a great rule of thumb, then its 50 gallons per person per day for residential use.

2. What about the vertical lift’s distance?

If you are familiar with the pumping industry, then you would have questions like “what is the total dynamic head?”  and “what is the head?” or something in these lines. All of these questions are asked to help in determining the amount of force or pressure needed for “pushing” the liquid up to where it’s required to go. Considering whether the system lifts to a septic tank, in the absence of any back pressure or to a sewer system with pressure pushing back, is imperative.

3. What are the requirements when it comes to solids handling?

Such type of requirements might be easily determined by the local codes. A sewage pump should have the capacity to handle spherical solids that are up to 2” in diameter, unless otherwise stated.

4. What is the size of the pump basin required?

Normally, the flow rate determines the size of the basin that is needed. A properly sized basin allows the water pump to run for longer on each cycle. It would also help to cycle less times each day. Generally, the larger the motor, the less cycles each day are recommended and the longer becomes the run time that is needed. Usually, the owner’s manual indicates the max number of cycles in a period of 24 hours. Taking this into account, with the flow rate, would help in determining what would be right for you. With higher flow rates, the basin’s diameter needed increases. 

Therefore, if you’re looking for the right sewage pump for your system, then make sure to answer these questions beforehand.

Understanding the importance of water pump safety

Whether you are using sea water pumps, or any other kind of pump, it’s important to remember to take out the extra amount of time for learning about the pump safety. When it comes to submersible water pumps, they do not really seem dangerous. However, if they aren’t fitted & operated properly they can cause personal injury, which at times can be fatal.

Therefore, this blog is devoted towards sharing a few tips on water pump safety. Although, this blog does not include every tip there is to know, but it is intended for reminding you of some of the basic ones.

Have a look at the following:

1. Owner’s manual

It does not matter whether its seawater pumps, or dewatering pumps, or which brand’s pump you have decided to purchase. Every company out there, has the information on how to operate their own manufactured pumps, that too with the highest level of safety possible. Although you may think that the safety fundamentals are always the same, and it is true, the specifics of it, often differ. This is where it depends on which brand as well as what type of pump you are getting installed. Therefore, you should make sure that you read the owner’s manual provided with the pump & comply with the procedures laid down therein.

2. Safety guards

When you are dealing with water pumps, it is highly crucial to always make sure, that all the safety guards both mechanical as well as electrical, are in place while the pump is being operated. Not only should you make this sure with the safety guards, but also with the shields of the water pump being operated.

3. Control device

All pump manufacturer will advise you to install safety device like control panel along with its pumps. Many a times this suggestion is treated as an optional thing. However, it is advisable not treat this as an option, but to look at it as necessity, as it will help you in long run if there is any malfunction with the pump. Many reputed manufacturers have features which gives you inbuilt protection against Overheating, Mechanical Jamming, Dry running etc, when connected to control panel.

Apart from these three basic tips, there are a few others, that teach to never use a water pump for fluids that it wasn’t designed for, to always keep the pump at least 3 feet away from the walls and other equipment during its operation, to never use a pump in an explosive or flammable surrounding etc.

All in all, beware of the pumping accidents, and stay safe by applying these basic safety tips. For reliable dewatering submersible pumps and other submersible pumps in India, call 9981992833.

Exploring the world of Submersible Pumps

When it comes to the world of water pumps in general, there are many options. Each pump has a different design and serves a different purpose. They differ in sizes, shapes, capacities, prices etc. They also differ in quality depending on which provider the customer chooses to go for.

However, in this large world of water pumps, there is also a unique category of pumps i.e. the submersible pumps. The general perception is that submersible pumps are good or are available only as sewage pumps. Is it so?

No, today there are few good companies who are offering Submersible pumps for all kind of water processes. i.e. from pumping Clear Water to Pumping Slurry. In this article, we’ll be sharing the very basics of a submersible pump.

• How does it get its name?
A submersible pump is called so because of its ability to operate in fully submerged condition, in water. It is also known by the name of an electric submersible pump.

• The motor of a submersible pump
The motor of a submersible pump is close-coupled (mounted on common shaft) to the pump & is like a heart of the pump. Sealing forms a very important aspect of motor, sealing can be either mechanically sealed or it can be hermetically sealed.

• The basic function of a submersible pump
A submersible pump basically aims at pushing the water to the surface. It functions in this way by converting the rotary energy into kinetic energy and further converting that into pressure energy.

• How does the pump execute this process?
This process is executed by pulling of the water into the pump. Firstly, it goes in the intake. This is where the rotation of the impeller starts pushing the water through the Volute. And then, from here, it finally goes to the surface.

• Why are submersible pumps advantageous?
Few of the major advantages of a submersible pump is that it is self-priming, no suction lift limitations, no negative suction & less power consumption.

Add to this there is no noise pollution, no wastage of surface space, pump is not necessary & last but not the least it also acts as a protection against possible theft.

• A tip of caution for using submersible pumps
The pumps must be fully submerged into the water, as it actually helps to cool the motor of the slurry pump. However, if the pump is used out of water, it may lead to overheating & burning.

In the end, if you are planning to go for a pump, its always advisable to check whether you have an option in submersible pumps & chose are the type that suits your purpose, keep these advantages in mind and go ahead about it. You should however, make sure that the quality you are attaining is great and reliable. For our product details get in touch at 99819 92838.

Tips to Save Energy on Pumping System

As renowned drainage submersible pump suppliers and providers of dewatering submersible pumps in India, in the first part of this blog, we managed to share with you 3 great tips on saving energy on your pumping system. 

Taking the same discussion further, here are 4 more tips to save energy on pumping system -

1. Minimizing the system pressure drop

When you think about minimizing the system pressure drop, the best way to do so is through pipe-sizing optimization. The hydraulic friction loss would create a decrease in pressure from one end of a straight pipe to the other end of the pipe. The factors that influence the system pressure drop are pipe size (diameter), flow rate, pipe characteristics (material, surface roughness, etc.), properties of the fluid being pumped and overall pipe length.

2. Implementing proper control valves

The control valves are used in controlling pressure and/or flow. They can assist in reducing energy losses over non-controlled systems like multiple locations with different elevations and distances as well as irrigation systems that have a fixed-speed pump. However, The main functions of control valves are bypassing flow or throttling flow. The throttling process decreases the flow. On the other hand the process increases the pressure. Minimizing excess pressure is possible by bypassing excess flow back to another location or the reservoir.

3. Implementing (VSDs) variable speed drives

The drivers are used for variable-speed operation or fixed-speed. Energy can be saved for many applications simply by implementing variable speed drives. With the help of a variable speed drive, the rotational speed of the pump can be adjusted. This helps in achieving the appropriate head and flow that is required for the process. A variable speed drive often gets added to an existing pump motor system. This helps in slowing down the pump to fulfill actual requirements as compared to the theoretical requirements that come out at the beginning.  When a VSD is finally installed, it can accommodate changing system demands, that include a lot of potential future expansion plans. This proves to be a great method as it results in the lowest life cycle costs and the highest energy efficiency.

4. Eliminating unnecessary uses

Do not overlook this simple method of saving energy by eliminating all the unnecessary use. Such measures include using pressure switches to control the number of pumps in service as well as shutting down any unnecessary pump.
