Benefits and Drawbacks of Submersible Pumps

The primary disparity between a submersible pump and any other type of pump is that a submersible pump is fully submerged in the liquid that it is required to pump. These pumps can be used in numerous pumping applications. They also have their benefits and disadvantages, which should be considered when making a pump selection. Competent Engineers is an exclusive Kirloskar pump dealer in Delhi, India. Their submersible pumps have a unique design which makes them superior pumps for submersible applications. Ksb submersible pump in Delhi is capable of handling wastewater, sand, mud, gravel, slurry and more.

Submersible Pump - As the name implies, a submersible pump is created to work with the whole assembly, consisting of a pump and motor, completely submerged in the liquid or medium to be processed. This sort of pump has a hermetically sealed motor. This motor is close-coupled to the pump body. The water-tight chamber around the motor is filled with oil to save it from damage by stemming the entry of any liquid which may cause a short circuit.

After the pump is submerged there is favourable fluid pressure at the inlet of the pump and this condition can create more significant efficiency due to less energy needed to push the fluid through the liquid path of the pump. A submersible from Kirloskar pump dealers Delhi pump works by pushing, as opposed to drawing, liquid during the pumping cycle. This is incredibly efficient because the pump operates using the head of liquid in which it is submerged to operate and no energy is consumed in drawing the liquid into the pump. A buoyant effect from the pump being submerged is that the engine is cooled by the liquid around it, preventing it from damage due to overheating.

Many submersible pumps in the oil and gas industry work according to the Electric Submersible Pumping (ESP) principle. This cost-effective method of lifting large volumes of fluids from deep wells using the motors of an ESP system is planned to operate under high temperatures and pressures. They need special electricity cables from valve supplier Delhi India and can be costly to run.

Submersible Pumps - Advantages and Disadvantages

The submersible pump offers significant advantages over other types of pumps:

Priming: They don’t require priming. They are self-primed since they operate below the surface of the fluid being pumped.

Cavitation: As these pumps are fully submerged, submersible pumps are not inclined to cavitation. This can be a concern with centrifugal pumps and other kinds of positive displacement pumps.

Efficiency: When a pump is submerged there is favourable fluid pressure at the pump's inlet. This situation can increase efficiency as less energy is required to push fluid through the liquid path of the pump.

Noise: These pumps are very quiet in most applications since they are completely submerged in the liquid.

There are also some drawbacks to confront with:

Accessibility: Submersible pumps are usually not readily accessible for regular inspection or maintenance, especially in deep-well applications. This makes it hard to complete preventative maintenance and in many applications pumps are left to run until they stop functioning. This arises a need for replacement.

Corrosion: Prolonged exposure to a liquid of any type will lead to corrosion. The liquids used in submersible pumps are often corrosive and abrasive. Seals are particularly prone to corrosion leading to leaks and damage to the motor. To compensate for corrosion these pumps ought to be made of corrosion-resistant material. This can make them more expensive as compared to other types of pumps of the same capacity.

Submersible pumps should be examined as often as possible so that necessary repairs can be carried out to extend the life of the pump.

You should always contact a leading submersible Kirloskar fire pump dealer in Delhi India to ensure you have the right pump for your application to discuss your needs.

Types of Fire Pumps

Fire pumps are of paramount importance in many water-based fire protection systems. These fire pumps available with Kirloskar pump dealers enable the increase in water pressure (measured in psi and bar) from a water source when that source is not adequate for the system it’s supplying. These issues are very common in high-rise buildings that tend to have a high-pressure demand.

There are various types of fire pumps available. It is very important to have the correct pump installed in order avoid excessive costs and also to avoid excessive pressures which can damage the pump. It’s best to keep all factors in mind during pump installation that does not achieve the necessary pressure requirements. There is a possibility of where it could require a new pump to be installed.

Following are the two categories of pumps available in the market:

Positive Displacement Pumps

These pumps are characterized by a method of producing flow by capturing a specific volume of water per pump revolution and pushing it out through the discharge line. For example – a bicycle tire pump is an example of a positive displacement pump we commonly see. They create high pressures but have limited flow volume as compared to the centrifugal pumps.

Centrifugal Pumps

These are the most common fire pumps and are used with most systems. Here the pressure is developed by the action of centrifugal force or spinning. Water in centrifugal pumps enters the suction inlet and passes to the centre of the impeller.

These pumps can handle large volumes of water while providing high-pressure boosts.

Let’s understand how does a fire pump work?

A fire pump is an integral part of a fire sprinkler system, as it provides high-pressure water accessibility to the fire sprinkler system, increasing the flow rate of the water.

The full system is made up of the motor - or driver - and the controller. A fire pump receives water from underground water supply or a water tank, and is powered by electricity or diesel fuel.

The high-pressure supplied by the pump distributes water through the sprinkler system and hose standpipes.

Common types of fire pumps include the horizontal split case, vertical split case, vertical in-line, and vertical turbine. Deciding which Kirloskar pump dealers in Delhi, India have the right pump appropriate for any given facility should be discussed with the design engineer, a fire safety professional, and the Local Authority Having Jurisdiction (AHJ).

The most common type of fire pump is the horizontal split case.

Most economical for higher flow applications

Easily accessible for repairs or maintenance.

Long lifespans and size availability

Vertical split case fire pumps

Similar to horizontal split case fire pumps

Take up less space due to their vertical design, which also protects the pump from potential flooding damage.

The vertical in-line pump

A single-stage centrifugal pump designed, as the name implies, for vertical installation.

With suction and delivery in line with each other, this pump provides a smooth flow of water throughout the system

Makes it ideal for small spaces.

The design does require the pump to be removed for any repairs or maintenance.

The vertical turbine

A centrifugal pump designed for fire pump services where the water source is located below ground.

This fire pump comes in varying types such as oil-lubricated enclosed-line-shaft and water-lubricated open-line-shaft pumps.

Both types of turbines are designed for installation in drilled wells, lakes, streams, open swamps, and other subsurface sources.

Different pumps can be used in a variety of situations. When demand of your  system exceeds, what your water supply can provide than it’s the time to look at what a fire pump can do to bridge this gap. Competent Engineers are well-known Kirloskar fire pump dealers in Delhi.

Pumps and Valve Dealers

In the industrial sector, industrial pumps and valves by Kirloskar Pumps Dealers in Delhi, India are essential components for fluid transfer. Pumps move enormous amounts of fluid from one location to another mechanically. Valves are used to control the flow of fluid in a specific location by opening, closing, or partially blocking the flow. The fluid handling method differs depending on the industrial sector. As a result, there are many different types of industrial pumps and valves, each with its function and purpose.

Here are a few reasons why Competent Engineers should be your first choice for pumps and valves:

Design expertise: They specialize in producing a wide range of pumps and pump parts, including casings, critical impellers, diffusers, glands, covers, and bodies of all types of pumps for a variety of industrial applications. They've all been meticulously designed to survive a variety of pressure and corrosion tests.

Excellent research and development: The R&D department has built a solid reputation for developing unique and indigenous binder formulations throughout the years.

Some of the numerous types of pumps offered are:

Centrifugal Pumps - Pumps of this sort are the most frequent in use around the world. This pump is sturdy, efficient, and relatively inexpensive to construct. The fluid pressure will rise from the pump's input to its exit whenever the pump is in operation. The liquid will be pushed throughout the system by the change in pressure. By passing mechanical power from the electrical motor to the liquid through the spinning impeller, this type of pump increases force. The liquid flow enters the impeller's center and leaves through its blades. The centrifugal force increases the fluid's velocity and allows kinetic energy to be converted to force.

Vertical centrifugal pumps - Because the bearings are external to the pit, these pumps have a unique shaft and maintenance design that allows the volume to fall within the pit. This type of pump does not employ a filling container to cover the shaft, instead opting for a throttle bushing. A parts washer is a common application of a parts washer.

Submersible pumps - Stormwater, sewage, and septic pumps are all terms used to describe these pumps. Building services, domestic, industrial, commercial, rural, municipal, and rainwater recycling applications are the most common uses for these pumps. There is a wide range of options available for various uses, including high flow, low flow, low head, and otherwise high head.

Fire-extinguishing pumps - Hydrant boosters, fire pumps, and fire water pumps are all terms used to describe fire hydrant pump systems provided by Kirloskar Fire Pump Dealers in Delhi. These are high-pressure water pumps designed to increase the capability of construction firefighting by raising the force within the hydrant service when mains are insufficient. Irrigation and water transmission are two of the most common uses for this system.

Valves are mechanical devices that open, close, or partially restrict the flow of water to control, direct, and regulate it. They can be made of a variety of materials, including bronze, PVC, brass, and other metals. Valves are used to guide the flow, shut off water access, prevent backflow, and control water pressure in residential and commercial buildings, water supply systems, wastewater treatment plants, and chemical factories. The type of valves by Valve Supplier Delhi, India, that are mostly used:

Gate Valve - In plumbing systems, the gate valve is the most common form of valve. It has a wedge-shaped metal gate that may be lowered to stop the flow of water or elevated to enable the flow to continue using a twist-type lever or knob. Because gate valves are designed to be fully opened or fully closed, they cannot control the water flow. It can wear out the valves if used to alter the water flow. All types of fluids, including air, fuel gas, feedwater, steam, lubricating oil, and hydrocarbons, can be circulated using gate valves.

Butterfly Valve - This valve is known as a butterfly valve because it contains a rotating metal disc that enables and inhibits water flow, generating an image like that of a butterfly. These valves are substantially lighter than the other types since they are small, light, and short. The hole in the sphere is aligned with the pipe in the open position, allowing water to flow through it. When the sphere is closed, the opening in the sphere is perpendicular to the pipe, preventing water from flowing freely. The lever handle also functions as a status indication for the valve, indicating whether it is open or closed. The valve is closed when the lever is perpendicular to the pipe.

Valve Globe - In plumbing applications where the flow must be regulated regularly, the Globe valve is widely used to regulate or limit the water flow. A stopper on the end of a valve stem that is raised and lowered by the valve's twist knob is one of the interior design characteristics. Globe valves acquire their name from the shape of their bodies, which resembles a globe or a ball. Globe valves are commonly used for outdoor faucets and other utility faucets because they are good at regulating flow.

The Pressure Relief Valve is a valve that is used to relieve pressure. Pressure relief valves are used in the plumbing system to reduce water pressure to a safe level and prevent the bursting of equipment or piping systems. The mechanism is made comprised of a spring and a diaphragm that is adjusted to a certain limit based on the water pressure.

Choosing the right kind of industrial pumps and valves by Kirloskar Pump Dealers in Delhi for your unique demand will be the best choice. All the pumps and associated parts are manufactured of the highest-grade alloys, including ferrous, duplex stainless steel, nickel, and chromium. The valves and valve castings have also proven to be quite durable.

Fire Protection Systems

A fire can double in size every 15 seconds for a very fast-moving fire and up to every 2 minutes in a slow-moving fire. However, this time also varies based on what is burning, and if it is a controlled area (heat is trapped and burns faster). Depending on the size of the space, the fire grows much faster than most people realise. Kirloskar pump dealers in Delhi, India have the best quality fire protection pumps available.

All fires can be extinguished by cooling, smothering, starving or interrupting the combustion process to extinguish the fire. extinguishing a fire by cooling it with water is one of the most common methods.

Fire can be very dangerous. It is impervious to ascertain that you do not endanger yourself or others while attempting to put out a fire. 

For this reason, when a fire is discovered, the following Rules for Fighting Fires work the best:

Sound the Alarm Systems - If you discover or suspect a fire, sound the building fire alarm. If there is no alarm system found/installed in the building, warn the other occupants by knocking on doors and shouting (creating noise) as you leave for a safe escape. Kirloskar fire pump dealer in Delhi provides all kinds of fire protection systems.

Escape to a safe place - Rescue yourself through the fire before attempting to rescue others. Move away from the building and ensure you are out of the way of the fire department. Never block the escape route or the area from where firefighters are entering. Don't go back into the building until the fire department says it is safe to do so.

Alert and acting on impulse - Call the fire Safety department immediately. 

Total and immediate evacuation is safest. Only use a fire extinguisher if the fire is very small and you know how to do it safely.

If you can't put out the fire, leave immediately. Make sure the fire department is called -- even if you think the fire is out. However, before deciding to fight the fire, keep these rules in mind:

Never fight a fire if  (Rules)

You don't know the source of the fire burning. 

The reason is -if you don't know what is burning, you don't know what type of extinguisher to use. 

There is a danger of explosion or producing toxic smoke if the right fire extinguisher is not used.

Fire will spread rapidly beyond the spot from where it started. The time to use an extinguisher is in the incipient, or beginning, stages of a fire. If the fire is already spreading quickly, it is best to simple evacuate the building, closing doors and windows behind you as you leave.

Let the experts do their job - call the firefighting team

The final rule is to 

Always position yourself with an exit or means of escape at your back before you attempt to use an extinguisher to put out a fire. 

In case the extinguisher malfunctions or something unexpected happens, you must be fully prepared to move out quickly instead of getting trapped. Just remember, always keep an eye on the exit and escape fire to ensure help can be called. 

The best way to safeguard yourself from getting trapped in a fire incident is to install a fire safety system. Some types of fire protection systems available with Kirloskar pump dealers have the automatic dispatching of emergency services. These systems will work to immediately suppress the fire, while also notifying the authorities to send emergency professionals to your location.
