Dewatering Pump

Uses For The Modern Dewatering Pump

It would be something of a surprise for most people to learn just how dependent upon pumps and pipes our modern lifestyle has steadily become. Although their uses are many, these facilities remain largely hidden from the general public and are known only to those who work closely with them. However, should any of these major pumping operations, which includes the dewatering pump, fail at any time, the consequences would be noticed at once and could turn out to be quite dire.

The dewatering pump, for instance, plays many vital roles of which the majority of the population remain blissfully unaware yet, in many cases these roles may be crucial to our continued good health and even to our survival in some cases.

dewatering pumpsIn densely populated urban areas, sewage disposal is a major undertaking. It’s not simply a matter of putting enough distance between ourselves and our natural wastes but also one of processing to render it safe. A vital stage is the removal of liquid from the bio-solids by a dewatering pump.

With the growing concern for the environment, purification of the solid component of sewage and its conversion to natural organic fertilizers along with the treatment of liquid to provide potable water are vital processes made possible by their preliminary separation.

As with any pump used to transport solids, there’s a danger of damage to impellers and thus some ongoing programme of inspection and servicing is needed to reduce the chance of critical failures that might result in hazards to health. A dewatering pump will benefit greatly from this simple precaution and, as a result, its useful lifespan may be extended considerably while also cutting both operating costs and downtime arising from the need for repairs or replacement.

Often Needed to Operate Below Ground

Among the many industries that are of prime importance in maintaining our modern lifestyles, the two that most people are aware of are mining and oil. Both play a vital support role in other industries as well as in our domestic lives. Both also make use of the dewatering pump below ground.

Deep level mining in South Africa may occur at depths of several kilometres and flooding from deep level aquifers is a constant hazard that, if unchecked, could halt all progress and present a serious threat to life and limb. The centrifugal pumps employed for ongoing drainage of water in these situations are what make these deep level mining operations both feasible and safe from at least one source of danger that miners face daily.

The oil industry too makes use of the versatile dewatering pump. On a drilling rig, for instance, these units will be used in the separation of sea water from crude oil as well as in the de-oiling of waste water. Having become far more sensitive to the potential impact of crude oil contamination on the marine environment in recent years, and faced with the prospect of huge penalties, the oil companies now regard the latter process as being just as important as maintaining the flow of the black gold itself.

The dewatering pump has a place in the building business also. With land suitable for domestic and business development shrinking rapidly and rising even more rapidly in price, builders are eying sites that may once have been thought less suitable. These include areas where the natural surface drainage is poor and where it would be impossible to excavate the foundations without first removing the excess water.
Two techniques are used for this purpose. The first rings the site with deep wells, each with its own submersible pump while, in the well point process, narrow bore tubes are used to draw out the water using the vacuum created by a pump above ground.

Protect Productivity With Mine Dewatering Pumps

Mining has long been one of the most productive South African industries. The country is well known for its production of precious ores and minerals, such as gold, platinum and diamonds. As these mining operations reach maturity it has become necessary to delve ever deeper into the Earth’s crust in order to access this mineral wealth. These mining operations, which are today the deepest in the world require mine dewatering pumps that can cope with a variety of different adverse operating environments. The depths at which mining is today taking place in South Africa mean that the country has become one of the world’s leading authorities on mine dewatering pumps and the specialised solutions and expertise that have been developed in the country are today used all over the world.

The pumps that are used for mine dewatering must be able to operate in extremely hostile conditions that are characterised by high temperatures and the presence of large amounts of water, which is often contaminated by additives which can adversely affect the operation of the pumps. In addition the pumps are often situated deep underground where servicing is difficult and time consuming. Any downtime can result in significant losses for the mining operation and given the marginal nature of many mines in South Africa this downtime can result in lost revenue that can affect the viability of the mine.

Mine dewatering pumps are extremely robust pieces of equipment and the pumps such as non clogging cantilever centrifugal pumps which are used as sump dewatering units must be capable of pumping liquids with a high proportion of solids and extremely abrasive fine material. Slurry pumps are also used for mine dewatering purposes where these extremely heavy duty pumps can cope with a variety of different environments characterised by abrasive conditions, as well as environments where corrosion can negatively affect the performance of pumps. These slurry pumps can also be used for environmental cleanup purposes and are often used in the paper and pulp processing industries where the ability of the pump to cope with abrasive materials is required for proper operation.

In even more harsh operating condition low speed slurry pumps are used. These pumps can be used for mine dewatering purposes but also find use in the dredging industry as well as other pumping purposes in the mining environment, such as process pumping and tailings disposal. These pumps include variants such as end suction and horizontal pumps which can cope with severe heavy duty usage. These pumps are characterised by low maintenance requirements and extremely robust construction that enables the pumps to operate in even the harshest of environments without significant downtime which can characterise less robust equipment when it is used in high temperature environments and harsh ongoing pumping requirements.

Mine dewatering pumps are essential to the ongoing success of the South African mining industry as mines reach deeper than ever before to reach ore deposits that until the development of the latest in pumping technology had been inaccessible. Pumps similar to those used for mine dewatering purposes are also used in geological exploration where water needs to be removed from exploration sites. These dewatering pumps are specifically designed to ensure the safety of the mine personnel and provide access to valuable resources that keep South Africa at the forefront of mineral excavation and position the country as the innovator of globally competitive mining technology.
