Industrial equipment endures chemical corrosion and high temperatures leading to wear and tear. Subsequently, demand for the equipment must be carefully weighed before making a purchase for higher efficiency, lower maintenance, and long-term cost savings.
The electric cables attached to the motor of the submersible pump are sealed hence they can be safely used in fluid medium or water. The pump and motor are tethered by a strong mechanical design and cannot be easily separated. Hence, if you have accurately measured the bore well diameter, finding a matching pump size, and installing it is easy and safe.
Analyze future requirements before purchasing the submersible pump; it will save significant money and time in energy bills and downtime, respectively. For instance, evaluate the purpose of the pump ' will it be used in a pond or for a watering hole that feeds a herd of dairy cows on your property? Perhaps, you need a heavy-duty pump to work efficiently in the wastewater industry? Since the durability of the pump depends on its run time hence installing a massive pump will be a waste of your money.
Understand the functioning of the motor to evaluate its effectiveness. Premium quality pumps work efficiently below their load limit. The full load amperage (FLA) rating is the best indicator to know how much workload the motor shaft can achieve. The impeller attached to the submersible pump must also be considered.
The pump head is another factor to evaluate. It is a measure of pressure a submersible pump can build. It's measured from the water/liquid surface that needs to be pumped.
Submersible pumps are either used for bore well or open-well purposes.
For bore wells, the equipment is used to pump water from 50 feet below the ground. Currently, these submersible pumps are used for depths feet below the ground. However, as the water table is rapidly decreasing, manufacturers are designing pumps for greater depths that match the size of the bore, such as 3', 4',5',6',7', or 8'.
Submersible cutter pumps are used for sewage treatment plants, drilling, water well and deep well dewatering. Other uses include residential apartments, industrial and municipal water circulation, commercial complexes, and irrigation systems.
An understanding of BS: with adequate structural waterproofing knowledge is essential to make a purchase for the basement. For instance, you should know how the water source flows through soil and interacts with your building. Usually, the selection of sump chambers is based on the expected water flow, soil structure, and area of the basement slab.
A sump pump removes accumulated water in a water collection system. A pump station refers to the pump chamber, internal pipe valves and working. It should have two sump pumps if used for groundwater purposes.
An electric motor is used in a submersible pump that can be oil or water-cooled. This pump can be any type, such as AC, DC, PMSM, Brushless DC, and/or SynRM.
Although submersible pumps are safely designed to prevent electrical shocks. For instance, electrical wiring and the unit's working parts are encased in cast-iron, cables sealed and shielded by rubber. However, this encasing cannot guarantee waterless contact of the submersible pump.
Hence, when installing the pump in your pond, water garden, or swimming pool, ensure that the pump is switched off and not connected with an electrical outlet; else you can be electrocuted. Always, take precautions, like wearing rubber boots and gloves, and the pump switched off when entering your pool for routine maintenance.
The life expectancy of the submersible pump depends on different factors, such as quality, electrical supply/voltage of the pump, and for how many hours it will be used. On average, for a residential 3-wire submersible pump, the shelf-life is 10-15 years, and for a 2-wire pump, it's 8-13 years.
You can continuously operate a submersible pump but be prepared to compromise on its shelf-life. Hence for better performance and higher durability, the submersible pump should operate intermittently.

If you are pumping liquids that contain solids, it is critical to select the right solids handling submersible pumps for your application to avoid motor burnout and clogs. In this article, Industrial Flow Solutions will help answer a few key questions to help determine which pump will solve your problems and prepare you to talk with your pump provider.
1. What Type of Solids Are You Pumping?
As IFS is focusing on wastewater in this post, they assume the solids are non-abrasive (note that abrasive solids require a hard metal, agitator pump). Most likely, these non-abrasive solids are large and soft or long and stringy. You also need to know if the solids need to be reduced to go into your system or to discharge, or if you just need to pass them.
Large, soft solids generally require a shredder pump that will shear the materials before pumping. Long, stringy solids generally require vortex pump that can pass the entire solid.
Understanding the type of wastewater is also helpful. These are generally categorized as municipal (including sewage) or industrial. While municipal wastewater is generally consistent from site to site, industrial wastewater solids and contaminants often vary based on the type of industrial site.
2. What Solids Loading Can the Pump Handle?
In order to keep the solids moving with the liquid, there needs to be sufficient liquid either in the sump or in the system; otherwise, the pump will clog. Most solids handling pump designs can handle approximately 5% solids by volume. If your wastewater has a higher solids concentration, you will likely need to change the system to allow more water to accumulate in the sump or to add water to the process.
The sump pump basin size is also a factor. The basin should be sized to minimize the number of cycles per hour but cannot be so large that solids will settle instead of being brought into the pump.
3. How Might Your Piping System Affect the Wastewater Pump You Need?
Understanding the design of your piping system will help your provider ensure there are no areas where the solids may settle, build up and cause clogs. This includes:
In some instances, your provider may conduct an inspection. If the entire piping system isn't visible, you may consider sharing the piping system plans or explaining where and how far the piping runs as well as explaining the piping connections and fittings.
4. What Is the Flow Rate Required for your System?
The flow rate is the amount of liquid that runs through the system in a given amount of time. The flow rate and pipe sizing determine the velocity needed to pass the solids downstream through the pipes. The flow rate also indicates if the sump Is properly sized. An undersized sump causes the pump to cycle too frequently and burn itself up.
If you don't know your flow rate, here are two options to help your pump provider determine it:
Translating Answers into The Correct Pump Selection
The answers to these questions provides the information your provider needs to make a recommendation. The type of wastewater and solids determine the type of pump type ' shredder pump or vortex pump. The flow rate and the amount of head in the system, will help determine the specific pump model required.
Additionally, you may have unique circumstances to consider, especially when dealing with harsh environments.
