Where are self-priming pumps used?

Some pumps are partially or completely above the fluid level. In these cases, air can come into the suction line and must be evacuated before using the pump. Self-priming pumps can remove this air on their own before the pump begins operating normally.

Self-priming pumps do not allow air and water to mix by creating a partial vacuum to expel water while also removing air from the pump. This happens because the pumps mix air and water during the process of priming and then force the air to rise while pushing the water down or sink.

Due to gravity, the water from which air has been removed is forced back into the impeller. Then the water mixes with the remaining air present in the suction line.

The process goes on over and over till all the air is removed and a vacuum is created in the suction line.

After this, atmospheric pressure forces water into the suction line, and the process of pumping can begin.

Advantages of Self-Priming Pumps

They can handle different types of liquids

Self-priming pumps are a good option for slurries and corrosive liquids

These pumps continue to pump liquids even after they are not submerged in a tank or vessel

Dewatering pumps for mining application

Mining operations require dewatering and safe disposal of potentially contaminated water. Proper mine dewatering is a critical component to every successful mining operation, regardless of the type of mining that is being done,  generally, mining dewatering requires high head, i.e., 100 to 120 meters with solid handling size of 40 to 60 mm.

Mining pumps refers to the pumps that are required for dewatering as a part of the mining process. Mining pumps are bifurcated on the basis of fluid transfer and application needs. Mining pumps work for rough sludge dewatering, mineral processing, slurry transfer, reagent (acid and chemical) dosing, water supply, and boosting waste water management and tailing transfer.

Let's have a look at various mining pump options available.

Slurry pumps- These pumps are planned for liquids with a combination of solid particles.The design and and construction of the pump can be changed to adjust to various kinds of slurry that differs in the concentration of solids, size of solid particles, the shape of solid particles, and composition of the solution. The slurry pumps are more sturdy as compared to liquid pumps because of sacrificial material used and replaceable wear parts to withstand wear due to corrosion. Centrifugal pumps as well as positive displacement pumps can be used for slurry.

Self- Priming pumps- Self- priming pumps move debris with ease and ensure hassle-free operation. These pumps provide strong suction of mud and rock and draws liquid, solids and other material from construction sites and transfers everything to the designated area.

Auto- priming pumps- auto-priming pumps offer simple, reliable operation and easy maintenance. Auto priming pumps are beneficial as they can run dry for an extended period of time as compared to other conventional pumps. These pumps are suitable for nearly all dewatering applications, especially in mining, straight dewatering and sewer by-pass dewatering.

Gravel pumps- these pumps are most commonly used to move sand to a far distance. Gravel pumps can also be classified as sand pumps or slurry pumps. These pumps have multi-purpose but most common being in mining, metallurgy, coal washing, power plants, sewage water treatment, dredging, and chemical and petroleum industries.

Dredge pumps- Dredging is the process of transport of underwater particles from one place to another, mainly sand, gravel or rocks. This process is most commonly used for the reclamation of land, desilting, flood prevention, creation of new ports or expansion of existing ports, and this is possible only with the help of dredging pumps.

Submersible slurry pumps- these pumps have a sealed motor attached to the pump body. The entire device is submerged into the fluid that is to be pumped and then the liquid is pushed out  the surface. These pumps are more efficient as compared to the jet pumps.

Vertical slurry pumps- These pumps are also known as cantilever pumps. These pumps use a shaft that allows the liquid to fall within the pit as the bearings are external to the pit.

Horizontal pumps- These pumps include a minimum of two otherwise more impellers. Every stage is fundamentally a divide pump. On a single shaft minimum 8 or additional stages can be arranged. All kinds of pumps have been providing as well as servicing this type of centrifugal pump.

Water pumps- Water pumps are ordinary instruments that pushes coolant through the engine block and the radiator to cool down the heat that the engine produces. These pumps use the centrifugal force and removes the coolant that is trapped between the impeller blades. A suction (vacuum) is created in the center area of the pump housing. Coolant is drawn from the radiator via the lower radiator hose into the water pump. The main working of water pumps thus involves transferring coolant to the engine to remove the heat and then throwing the coolant to the outside air. The water pumps can be divided into single-stage pump, two-stage pump and multi-stage pumps.

Centrifugal pumps- The centrifugal pumps are used to transport fluids by turning rotational kinetic energy into the hydrodynamic energy of the fluid flow, and the rotational kinetic energy generally comes from an engine or the electric motor. Centrifugal pumps are preferable for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering.

The choice of pump should be made depending upon the application factors and for this it is essential to have proper guidance and knowledge with regard to the same.

The mobile high-head pumps at Udyog Engineering are vacuum assisted and available with diesel engine as well as electric motor for above mentioned surface pumps.

Useful Pumps For Dewatering Applications?

In a layman’s language, dewatering means the removal of water. This process is used in various industries but most commonly in construction and waste management where the water is separated from solid materials using various kinds of pumps. So what happens is that in construction sites, the water is pumped out to lower the ground level of water to ease excavation below natural ground level. The various types of pumps that can be used for this purpose are as follows- 1.  Openwell Submersible pumps- The main advantage of these pumps is that the pump is placed at the same level as that of water and also such pumps require less operating space. 2.  End-suction pump- Such pumps are placed upon the surface. Thus, a long suction pipe is required to be lowered down in the water. 3.  Self priming pumps- These pumps provide automatic self-priming. It means that they can manage air, water, or both without the help of any separate priming system. 4. Auto priming pumps- Such pumps simplify the normal pump startup process since it uses a single start sequence irrespective of the priming status. 5. Non- clog pumps- Such pumps are used mainly where high solids are to be transported. For example, in mining, sewage etc. 6.Cutter pumps- Such pumps are designed to handle tougher solids that ordinary sewage pumps cannot handle. It provides clog free operation by squashing those solids. For all surface pumps, the prime mover can be an engine as well as a motor which makes it feasible for pumps to operate without electricity, even in flood-affected areas. Based on your unique needs and requirements, our team at Udyog Engineering Ltd. guides you on the pump you should choose so that you get the best of your investment and your project needs are met to your satisfaction.

Centrifugal pumps are used to move liquids by using rotational motors called impellers. Fluid enters the impeller along its axis and is pushed out due to centrifugal force along the circumference. Impellers are required to increase the velocity and pressure of the fluid to guide it to the pump’s exit.

Priming a pump refers to removing air from the pump and suction line. It is the most important thing to do before actually operating a pump. Neglecting priming can cause issues in pump maintenance and impact the downtime of the piping system.

These are the two main benefits for priming in centrifugal pumps:

Priming is vital to reduce the chances of pump damage in the start-up phase. It prevents the pump impeller from becoming air-bound. If air fills in the pump it will not be able to pump desired liquid.

Priming eliminates the risk of the pump overheating and can even cause damage to critical internal pump components.

Here is how the process of priming takes place:

The suction pipe and impeller are filled with water.

The pump is started after the delivery valve is closed.

The rotating impeller forces the water to the delivery pipe, opens the delivery valve and the water is sucked through the suction pipe.

A pump can be primed in different ways. They are as follows:

Manual priming

To manually prime a pump liquid is poured into it. This can be done using a funnel or directly pouring into the suction pipe. The pump will be primed with the help of a gravity feed.

By using a vacuum pump

A small vacuum pump is used here to prime the main centrifugal pump. The suction line of the vacuum pump is connected to the discharge line of the centrifugal pump. The small pump removes all the air from the primary pump and suction piping.

Using a jet pump

Water from a high head is made to flow through a nozzle in this method. The pressure outside the nozzle is less than atmospheric pressure. So it is possible to suck water from the sump.

Installing a foot valve

In this method a foot valve is installed in the suction piping to make sure that liquid doesn’t drain from the casing of the pump once the pump stops operating. Once the pump stops and the foot valve’s port closes, the liquid can’t drain back into the suction pump because the valve is tightly sealed.  

There are some situations where priming a pump isn’t required.

Let us look at what those are:

When the pump is submerged

If the pump is at a lower elevation compared to the supply so that the pump suction will be filled with liquid all the time

In case of self priming pumps

With some basic modifications, centrifugal pumps can be made self-priming. This means that the liquid stored in the pump has the ability to generate a vacuum on the suction line. Even a self-priming centrifugal pump cannot operate when dry.

To get the most out of your investment while buying centrifugal pumps, make sure to get it primed at the right time. If you purchase from a reliable and well-established dealer, they will guide you on this process.

A sewage pump moves waste solids and liquids from one place to another. Residential sewage is typically made of soft solids with a diameter of up to 2 inches. The sewage goes from the sewage basin to a septic tank or sewer.

Since the sewage pump is often located at the lowest point of your sewage basin, it is submerged and is also known as the submersible sewage pump.

The pump can be manual, automatic, or dual-mode.

How does the pump work?

Sewage pumps have centrifugal pumps that allow the passage of solids through them without clogging up the pump.

The motor of the pump rotates the impeller which pushes the water due to the pressure created which then flows to the discharge pipe.

Sewage pumps are of three types:

Solid handling pumps- Also known as sewage ejector pumps, they are used to move raw sewage. Raw sewage has a lot of solids, which cannot be handled by all pumps. These pumps are ideal for handling solids and should be used for raw sewage.

Effluent pumps- These are small pumps that are placed using an on-site system. They are used for pumping the effluent that comes from septic tanks. Since the solids are left in the septic tank, the effluent is generally a clear liquid. Effluent pumps can pump out easily and efficiently since they don’t have to handle solids.

Grinder pumps- This pump is similar to the solids handling pump. The difference is, the motor in this pump has rotating blades. These can be thought of as garbage grinders. They take the solid waste and cut and grind them into smaller chunks before pumping them out.

Sewage pumps are helpful to remove water build-up from basements or spaces that are prone to flooding.

Here are their benefits:

They help prevent damage from flooding- In case heavy rains cause a flood in your basement, water can damage the floor and other furniture inside. With a sewage pump, this can be managed.

Prevent mildew and mold development- Mold can develop due to continuous dampness in an area. This can cause damage to property and pose serious health problems too.

Fire prevention- In case water floods the area where you keep your appliances like a washing machine or heating systems, there is a risk of short-circuiting. This can also cause a fire risk. A pump keeps the area dry and free from this danger.

Different kinds of facilities have varying needs and thus require pumps specific to those needs. Get in touch with us at Udyog Engineering, and we will guide you to the best suited pump for your business.

Fire pumps are among the most commonly used pumps for fire fighting in the world. These pumps are life and property savers. A good fire pump is easily portable and can be moved around to the affected area. They operate using diesel or electricity. Fire pumps are particularly useful in high-rise buildings or storage warehouses. Even in buildings that are lower-set, fire pumps are integral to fighting fire hazards.

To protect your assets it is vital to get a pump that is well-designed and is installed professionally. Let us understand the working mechanism of a fire pump:

These pumps are typically run using a diesel engine or electric motor. If a particular building needs power independent of their power grid then it is recommended to use a pump with an electric motor.

The pump starts when the pressure in the fire sprinkler system falls below a certain threshold. If more than one sprinkler is turned on at the same time, the pressure threshold tends to fall.

As part of the fire sprinkler system, a fire pump receives water from water bodies, or a water tank which is then supplied at high pressures through the sprinkler system and hose standpipes

Usually fire pumps have a horizontal split case. These are most economical and also easy to maintain and repair. They also have a long lifespan.

End suction fire pumps are another great option. These fire pumps have a casing where the suction comes in at one end and the discharge comes out on top. These are the most common centrifugal pumps and their configuration is the least expensive.

To determine which pump is best suited for your facility, get advice from your design engineer, or the supplier you are purchasing from.

Udyog Engineering Ltd. is among the most reliable and established suppliers of fire pumps in India. When you purchase from us, we also offer expert guidance on the kind of pump you should choose, keeping your unique needs in mind.

Fire protection systems must be reliable in their operation. They are essential for fire fighting particularly in high-rise buildings. Their perfect functioning ensures that water will be delivered properly to put a fire out. Udyog Engineering provides electric and diesel-driven fire pumps and other equipment that forms a fire-fighting system. The fire pumps begin to work when the pressure in the fire sprinkler system falls below a threshold.

Fire pumps fall into the following categories:

Hydrant Pump These are high-pressure electric and diesel-driven fire pumps made especially for fire fighting. They are best to use in a building and work by boosting the pressure in the hydrant service. They are the most common water-based suppression systems for fire hazards.

Sprinkler Pump A sprinkler pump is powered by diesel, electricity, or steam. It draws water from a water tank or water body like a lake. It could also directly be powered by diesel. Water is distributed from the sprinkler system of the pump due to the high pressure of water. The pump provides water flow at high pressure to hose standpipes.

Jockey Pump This is a small pump which connects to a fire sprinkler system so that pressure in the sprinkler pipes is maintained. Even if a fire sprinkler is activated a pressure drop is created and the jockey pump makes up for this pressure drop.

Booster Pump A booster fire pump is used to support the supply of water from a public or private source in case the pressure requirements of the protection system are beyond the capacity of the current supply. These pumps require regular inspection and testing to ensure reliable operation. These pumps are suitable to install in residential properties, malls, hospitals, refineries, and industries. Udyog Engineering is one such supplier of fire pumps and engineering products in India, who offer customized fire protection packages to their customers.
