Top 5 tips to choose the right water pump for your place
Posted by Daniel Hopkins on 26th Aug 2016
Water is scarce. Approximately, over a billion people (one-sixth of the world's total population) living in the developing world still don't have access to clean and safe water , yet somehow we have come to take it for granted. In some parts of sub-African territories, people still spend entire days looking for sources of fresh water to use, and is one of the prime reason’s that limit the growth of civilization in the area. Scientists have long since proclaimed that water is the lifeblood of our environment, quintessential for the survival of all living beings, including us. So why is it that the most abundant commodity present in the world, is also rapidly diminishing to be the most scarce?
Considering two-thirds of our planet’s surface remains occupied with water, sometimes it becomes unfathomable for us that only less than 3 percent of that water quantity lies in fresh water. Fresh water is the water that is usable by us for domestic or household purposes in our homes like drinking water or pool water, etc. Around 68 percent of this fresh water is stored in the icecaps and glaciers, only about 0.3 percent of it is encompassed within surface-level bodies of water like the lakes, rivers, and swamps, and just over 30 percent of the remaining fresh water is found in ground water. It seems extraordinary to comprehend that the same water that sustains all terrestrial and aquatic life on our planet is actually so scarce.
Australia— ‘the continent of extremes’ , lives up to its name in context to water resources as well. Virtual profusion noticeable in the scarcely populated north is in sharp contrast to the comparative shortfall in the more populated south. In addition, both are impinged by seasonal conditions and declining rainfall. Poor governance in the past have led to the over allocation of groundwater supplies and there is an increasing competition for the same water sources for agricultural, urban, and industrial usage. As a consequence, marking along with this startling realization is the consciousness that we have to operate this resource very carefully. And also the fact that this immensely important commodity to survive, is also becoming increasingly harder to dig up.
Living as part of the developed world, we have grown to be evidently nonchalant towards the benefits of fresh water accessibility we are offered every day. You might not have realized this, but a simple water pump has been helping improve your life, giving you the privilege of a commodity many till today find illusive. Water pumps can extract water from deep within the earth’s surface, and transfer them via hoses, powered by some mechanism or the other to satisfy our daily needs. Water pumps come in various makes including electric water pumps, that uses electronic energy to power itself, as well as petrol or diesel powered pumps. Pumps can also be portable or submersible, depending on your needs and comes in multiple price choices for variable budget requirements.
Importance of Water Pumps in various walks of life
Water pumps are the boon that impedes us from walking long distances to salvage water, or to dig up our own wells. Owing to the effectiveness of water pumps, now filling up water into any storage container is just a mere push of a button away. Water pumps have found ubiquitous adoption across agricultural, residential, industrial, and commercial utilization, for this very reason. Water pumps can also be used to deliver and transport various other forms of liquids as well. With that said, let us take a look at the various avenues in a little that water pumps have found employment in, and highlight its importance for the same:
- A water pump is one of the most important pieces of equipments deployed in your house. It takes the water from storage tanks or water wells and supplies them uniformly to your bathroom or kitchen sink. Water sprinkling systems in your garden can also be automated via water pumps to supply adequate amounts of water in your lawn. It can also be used is to pump out collected rain water that might have accumulated in your building’s basement.
Utilization in Farming
- Around 2.5 billion of the 6 billion population of the world is involved in farming-related activities, mostly based in rural areas. Being a major producer as well as an avid exporter of agricultural products, Australia has around 325,000 employed in the domain. Australian farmers cover over 135,000 farms, encompassing around 61 percent of Australia's landmass.It is safe to say, none of this demographic would be successful without adequate water supply throughout seasonal changes. An efficient water pump plays a significant role in the water supply system required for irrigation. Water pumps transfer water from various water sources like wells, lakes, rivers, and streams to farm lands and animal sanctuaries. They can also be used to spray liquid fertilizers on your harvest.
- Industries are major consumers of water, possibly all manufactured products utilizes water in some form or the other during some element of the production process.At the heart of any industry thus, lies adequate water supply. And any water supply system needs to be aided by a robust water pump to transport water from the tank to the required spot or to maintain ample water levels in their tanks to handle all operational activities seamlessly.
- One of the first images that come to mind, when one talks about putting out a fire, is that of a fireman attaching a hose to a fire hydrant that will enable him to spray water over the fire. Water plays an immense role in stopping a fire from propagating, as when water reaches a flame, it reacts and vaporizes to form water vapor. This water vapor increases in volume and takes the air out of the flame. This helps in negating the combustive nature of the blaze. Any sprinkler system for example, is fitted with a water pump that when asked to can suck water out from the storage reservoir and apply force to transport it uniformly throughout all the floors of a building.
The various components that make up a Water Pump
Water pumps allow you to meet the diverse water requirements for manifold utilization options at different levels. Their competence and performance depends on the effective functioning of their combined components. It might hold you in good stead to know a bit more about the varied components of a water pump before deciding to invest in one:
5 principal components of a water pump
- It is the name referred to the outer covering that offers a shield to the pump. Traditionally, this component is made up of robust metals like aluminum or cast iron, although some modern pumps do sport tardier stamped-steel housings.
- The impeller is the name given to the rotating component of a pump . The water is forced through the impeller, beyond which it is guided by the housing. Typically made up of steel, iron, brass, or bronze, impellers are accountable for rotation and allocation of the water all over.
- A water pump bearing is a ready-to-fit unit that consists of a shaft held by numerous rows of rolling elements in a through hardened outer ring. Bearing assembly tenders the requisite motorized support that allows steady rotation of the impellers.
- This is the part that is fixed firmly to the bearing assembly and delivers control for the rotation of the impeller. The measurement from the mounting gasket surface to the outer area of the hub, where the pulley is bolted can be referred to as the hub height. This is especially helpful if you wish to know your water pump is in a long or a short style.
- Just as a water pump serves as the heart of any water supply system, the seal is often regarded as the heart of the water pump machinery. The main purpose of a seal within a water pump is to protect the bearing assembly from a variety of exterior pollutants and contaminations. This function is highly critical as if these contaminants are not stopped from entering the bearing assembly, the bearing’s lubricants are washed away, and the pump becomes more prone to damages.
The importance of a water pump seal
As mentioned previously, the efficient performance of a water pump depends upon the seamless functioning of the various components involved in a water pump in ‘sync with each other. Even though the breakdown of any part of a pump can lead to an amalgamation that eventually results in the pump being hindered in its quest to transport water from a source to its destination, the pump seal is often considered the most pivotal part of a pump. The seal is tasked with the significant functionality of the protection of the pump’s bearing assembly. Premature failure of the seal from this primary duty thus almost always coincides with the shortening of the lifespan of your water pump. Thus, it becomes gravely important to understand the causes that might lead to the failure of the pump seals, in order to keep the pump functioning for as long as possible.
The primary reasons for water pump seal failure
Without proper supervision of the seal alignment, a water pump seal can prematurely fail to live up to its lifespan and it all goes downhill in a short space of time. With advancements in technology coming up leaps and bounds every day, contemporary seals have evolved from the two-piece ceramic designs that were used previously, to the more up-to-date silicone and carbide composite substances. Most seals in production today are shaped into an element and spring-loaded in order to exert the exact amount of pressure on the seal. This ensures that the working height of the seal does not get affected by mechanical tolerance levels.
However, here are some of the most common causes that can lead to premature pump seal failures:
High operating temperatures
- Uncontrolled levels of high operating temperatures for prolonged periods can lead to seal leakage and eventually, failure to function. This can happen for a number of reasons including heat aging (-a test to analyze the degradation of physical properties of an element as a result of exposure to high temperatures) of the elastomeric (-displaying both viscosity and elasticity) components, wearing down of the fluid film between the seal faces, and the potential deformation of the seal evenness.
- Considering the primary role of a seal within a water pump is to stop the contamination, it should be of no surprise abrasive contamination is the most common cause for the failure of a pump. The most common contaminators that work as an enemy for your pump are little particles of debris such as sand or rust. Other times, even processes like adhesive transfer from one seal to another can create a leakage gateway. As your pump ages, this will affect the functionality of your pump, but you could regularly check for contamination to increase the lifespan of your pump.
- Improper mechanical co-ordinates can also contribute to the premature end of your water pump’s life. Some of the common causes of such failures are— erroneous shaft or bore concentricity (-a compound tolerance used to establish a tolerance zone for median points of a spherical trait), bearing radial or axial play, mistaken seal installation procedures, as well as misalignment of components like pulleys or belts that leads to failure.
Avoiding premature water pump seal failures
Having identified the major causes of the premature failure of water pumps, contemporary manufacturers have devised several plans in order to negate or limit the possibilities of the same. The following are the steps involved in the manufacturing process, that aid in elongating the life of a water pump seal:
Since most faulty issues in water pump seal failures begin with the inability to comply with temperature standards for operational functionality, modern manufacturers use high-end elastomeric materials of the bellows design. Heat aging is a critical issue for pump efficiency and longevity, and the usage of the best possible materials help in negating the effects of the same.
The seal face materials that are preferred are adjudged on operating parameters, system concerns, as well as elongated pump life.
By exposing the seal’s mating ring to the coolant flows, the core temperature of the seal is kept under control while in use under operating environments.
Modern pump seals also come with Teflon-coated retainers that help in simplifying the installation process as well as minimizing the bore press fit leakage.
In conclusion, it is safe to say water pumps are amongst the basic necessities of life. Choosing the right water pump can help you in alleviating the pains involved in all your water transportation needs.
