Submersible pumps are not easy to source, especially if you do not know anything about the technology.
A little knowledge of common pitfalls may save your time, money, and frustration.
Here is a comprehensive guide to steer you through the process effectively.
Ignoring Application Requirements
Pump Type
If you use the wrong type of submersible pump for your application, there is serious performance consideration that may be affected.
There is, in general, different submersible pumps, such as dewatering ones, sewage handling, and industrial applications.
Each style has its characteristic and fitted for each specific application.
Type of Fluid
The characteristics of the fluid to be pumped depend on the type of consideration in the selection of the pump.
The viscosity, temperature, and chemical composition impact the material and feature requirements of the pump.
For example, the necessity to pump corrosive liquids necessitates that the pump be made from special materials like stainless steel or plastic.
Apart from such characteristics, it leads to short life spans of the pump and inefficiency and increased maintenance costs.
A close analysis of the fluid characteristics will ensure that the pump performs well and will last long.
Operating Environment
The operating environment is yet another critical factor that has to be considered.
The conditions for extreme temperature ranges, pressure variables, or potential contact with corrosive materials will be vital in modifying the performance and lifespan of the pump to a great extent.
For example, if the pump is submerged under water that is extremely cold, it would either require insulation or to be made from special materials such that it does not freeze.
Also, if the pump is exposed to abrasive materials, its need for enhanced protection features would arise.
Knowledge of the operating environment gives scope for better selection of pumps so that reliability and efficiency can be ensured.

Overlooking Quality Standards
Certification and Compliance
This is the prime thing while sourcing submersible pumps they must be conformed to the relevant Industry standards and regulations.
Look out for ISO certification or Conformité Européene among others; these are indications that the product has met minimum standards assured by the organization on quality and safety.
To be in compliance with internationally accepted standards will not only assure the reliability of the pump itself but also protect your investment by limiting the chances of its failure and possible liabilities arising out of such failure.
Always request the suppliers to provide documentation that proves their product meets the essential quality standards.
Durable Materials
The durability of materials of construction used in the pumps is an important investment in ensuring that the service life of the pumps is sufficiently extended, reducing maintenance costs.
Normally, submersible pumps are found in pretty harsh conditions; hence, materials used must be able to resist corrosion, wear, and abrasion if at all they are to perform optimally.
As a matter of fact, waste water plants use pumps whose construction material is able to withstand corrosive elements.
The use of hardy materials will greatly minimize incidences of breakdowns while increasing the life expectancy of such a pump.
Failing to Consider Total Cost of Ownership
Price of Purchase
While one can easily be seduced by desiring the lowest price possible, a single-minded fixation on that purchase price alone can become very costly in its own right.
For example, the low upfront cost can mean higher maintenance, lower energy efficiency, or a short useful life may result in money spent.
Total cost of ownership analysis enables you to make an informed decision.
Consider not only the cost of purchase but also the operation costs, maintenance, and replacement that may be needed in due course.
Maintenance and Repair Costs
Other important aspects to be considered in any assessment that is to be made on the economics of the submersible pump are the maintenance costs and repairs.
Some pumps, for instance, will need servicing now and then or may require special parts that are difficult to locate, thus increasing chances of longer downtime and increased costs.
You must consider the replacement parts; pumps using common parts would be simpler and cheaper to fix instead of those using special ones.
A well-maintained pump can greatly reduce your general cost.
Power Consumption
The energy efficiency is one of the key factors that most people overlook during purchase.
Submersible pumps can be power hungry, and their operating costs depend on that.
You can minimize this by opting for more efficient pumps.
This will go a long way in saving your money over time.
Seek out models that are designed to operate efficiently at your specific flow rate and head requirements.
Moreover, many pumps will provide variable speed options that can further optimize energy efficiency by tailoring the performance of the pump to exactly what the application needs.
Not Consulting with Experts
Technical Support
Professionals or suppliers in the area of submersible pumps can provide inputs that often remain ignored.
These professionals will be able to guide you through the selection based on your requirements and ensure that you avoid the common pitfalls made by all when attempting to minimize the risk of very expensive errors.
They can suggest pumps based on their past experience so that you can be certain you have selected a dependable pump for your application.
You are welcome to consult industry pros at any time to advise you in the selection process.
Installation Guidance
The proper installation of your submersible pump will ensure that you have the best performance and longest life out of your product.
An expert’s advice will keep you out of common installation mistakes, where both efficiency and pump life are mainly affected.
The professionals can advise on alignment, electrical connections, and safety measures that entail the best installation practices.
With this professional advice, you can minimize any possibility of issues arising due to poor installation, thus letting your pump be effective right from the beginning.
System Compatibility
Before sealing your deal on a pump, make sure the model you choose will work in harmony with your systems.
This encompasses everything from electrical specifications to plumbing connections, down to the general system design.
Expert consultation will bring forward any kind of issue related to the integration with systems so that the pump fits well in your set-up.
Compatibility ensures the best performance and eliminates post-purchase expensive modifications.
Neglecting Performance Specifications
Flow Rate vs Head
Every application has its flow rate and head demands, which, upon provision, the application will work accordingly.
Poor performance with unsatisfactory results is attained in case of failure to meet specifications.
Consult always the performance curve of a pump, which states or shows the ability of the pump to deliver a particular flow rate at different heads.
That is how you know whether your application’s flow and head demands will fall within the operating envelope of the selected pump.
Power Consumption
The review of the energy consumption of the pump is a key factor that determines decision-making.
In relation, pumps that have high energy efficiency levels improve operation costs and cause less pollution to the environment.
With such information, one can compare different models by inquiring about their power consumption ratings.
In such a case, opting for a pump that is designed for optimal energy use could entail saving money or reducing the carbon footprint of operations with huge savings over time.
Duty Cycle
The other important factor to consider is the expected duty cycle of the pump.
Duty cycle describes the frequency at which the pump will continuously run or in jolts.
Different pumps handle different types of duty cycles; selecting one that matches your operation is very vital.
For example, a pump meant for constant use must be strong enough to bear longer hours of operation without overheating or breakdown.
The duty cycle helps in understanding what could be expected from the pump application and subsequently helps you in picking up a pump that can bear the demand your application can place on it.
Disregarding Warranty and Support Options
Customer Support
Consider the level of customer support available from the manufacturer or supplier.
Great customer service will go a long way if issues arise past your purchase date.
Look for companies with prompt support, technical expertise, and effective communication.
Good support will help you sort out the problem in the shortest time possible to minimize your downtime and ensure smooth running of operations.
Replacement Parts Availability
Ensure the replacement parts for the pump are always available from the manufacturer or local suppliers.
A pump is only as good as it is maintainable; easy availability of its parts can minimize down-time, in the event of a failure.
At the time of selecting a pump, the availability of common replacement parts should be inquired from the person as well as the supply chain behaviour of the manufacturer.
This foresight will go to help you save a lot of precious time and money when repairs are necessary.
Conclusion
Sourcing the right submersible pump is not a straightforward endeavor, with quite a few factors to consider.
Avoiding frequent mistakes, you’ll manage to get the one best for your needs, running just effectively and efficiently as you’d want.
