Submersible Pumps Are More Efficient
It is true of centrifugal pumps that, when they are immersed in the fluid that is to be pumped, they will perform far better than when they are used to apply a vacuum via a pipeline to transport fluids. One of the main reasons for this is that, when they work below the surface of the fluid, they do not have to work nearly as hard. As well as this, one of the biggest threats to these pumps is the damage that may be caused to the casing and impeller vanes by cavitation if excess volumes of air get drawn into them when under extra stress due to heavy loads.
The long term effects of cavitation may lead to breakdowns and working hours lost, and may also result in the need for costly repairs. Clearly then, using the right pump for the job and using it in the correct manner are important factors in keeping any vital pumping operation up and running.
Where large amounts of fluid need to be cleared quickly and with less risk of costly delays due to downtime such as in most routine mining and oil drilling operations, making use of submersible pumps will most likely prove to be by far the best choice.
When working submerged, there are other risks. The fluid pumped may be corrosive or abrasive as with ore slurries, or carry a risk of fire such as when pumping petrol or oil to bulk tanks. Where an electric pump is immersed in fluid for use, it is also vital that no fluid can reach an area where it could cause a short circuit and thus, one very crucial aspect of the design of all submersible pumps is that their electrical parts must be isolated from the fluids they pump. When the substance to be pumped is flammable, this need becomes greater and special flameproof pumps are called for.
Pumping is a science and choosing the right pump for the job can be crucial for safe and effective service. Contact us for sound advice on submersible pumps, top products and expert service.
