Well pump systems are essential for moving water from underground sources, such as wells, to the surface where it can be used in homes, businesses, and other applications. However, maintaining and replacing these pumps when needed is critical to ensure optimal efficiency. While EV Pump specializes in servicing the surface pumps in these systems, understanding the entire pump setup is crucial for improving performance.
A well pump refers to the pump located at the bottom of a well, commonly known as a submersible pump. These pumps are designed to be submerged in the fluid within the well and are typically multi-stage centrifugal pumps. The primary job of a submersible pump is to move water from deep underground, up through the well bore, and into a storage tank located at the surface. Well pumps come in various types, each designed for specific well depths and water flow requirements. The choice of pump depends on the well’s depth, water yield, and the application for which the water is needed.
Submersible pumps are installed underwater in deep wells and are ideal for deep water systems. These pumps are highly efficient and are most commonly used for residential and agricultural needs.
In addition to their use in water wells, grinder pumps, a specialized type of submersible pump, are commonly used in wastewater systems. These pumps have built-in grinders that break down solids before pumping wastewater through small-diameter pipes to the main sewer system, reducing the risk of blockages and ensuring smoother operation in residential and commercial settings.
Jet pumps are used for shallow wells and are typically easier to install, making them ideal for homes with a limited water supply.
However, the submersible pump is only one part of the system. To move the water from the storage tank to where it’s needed - whether it’s for residential use, irrigation, or municipal supply - a second pump is required. This second pump, located above ground, plays a key role in ensuring the system operates efficiently.
Surface pumps are located above ground and are typically centrifugal pumps, which are designed to move water from the storage tank to its destination. These pumps are critical to the overall water distribution system and require proper maintenance to ensure consistent operation.
While submersible pumps handle the initial lift of water, the surface pumps ensure that water reaches its final destination. This division of labor between the pumps means that both systems must work in tandem for optimal performance. Weakness or failure in either the submersible pump or the surface pump can create inefficiency, leading to problems such as fluctuating pressure, inconsistent water flow, or even system failure.
These are the most common type of surface pump used in well servicing. They work by converting rotational energy, typically from an electric motor, into kinetic energy to move the fluid. Centrifugal pumps are highly efficient for applications requiring steady and continuous flow, making them ideal for transporting water or other fluids from the well to the surface and throughout the system.
These pumps move a fixed amount of fluid with each cycle, regardless of pressure. They are used in cases where precise flow control is needed. In well servicing, positive displacement pumps can be used for tasks that require high-pressure capabilities, such as boosting fluid into the well or ensuring consistent flow in a high-resistance environment.
A type of positive displacement pump, gear pumps are commonly used when handling viscous fluids or when high-pressure systems are involved. They are often used for moving oil, chemicals, and other thick liquids that need to be transported from the well to the surface or to processing equipment.
These are another type of positive displacement pump. Diaphragm pumps are ideal for transferring slurry, chemicals, or hazardous materials because they can maintain a sealed pumping environment and prevent contamination. They are frequently used for applications where dry run protection and leak-free operation are essential.
While not as common in larger systems, jet pumps are sometimes used in well servicing, particularly in smaller applications. These pumps use high-pressure water to create a vacuum and lift water from a well, making them suitable for shallow wells.
Even a minor issue in either the submersible or surface pump can have a cascading effect on the overall system’s performance. For example, if the submersible pump is not lifting water effectively or the surface pump is not pressurizing the water properly, the result is inefficient water delivery. Identify and address weaknesses as early as possible to avoid complications with the pumps.
If you're experiencing problems but you're not sure if you need a well pump replacement (the submersible pump) or if your surface pump (the pump above ground) needs servicing, there are several signs and indicators to help determine which one might be the issue.
Well Pump: If you’re experiencing irregular water pressure, it could be a sign that your submersible pump is malfunctioning. The submersible pump pushes water from the well to the surface, so a failure here might cause weak or fluctuating pressure.
Surface Pump: If you notice low or inconsistent water pressure but only when the system is running, the problem could lie with the surface pump. A surface pump that is clogged, worn, or experiencing mechanical issues will have difficulty maintaining constant pressure.
Well Pump: If your well isn’t providing any water at all, there could be a failure of the submersible pump at the bottom of the well. Common causes could include a burned-out motor, faulty wiring, or a pump that has become blocked or damaged.
Surface Pump: If you are surfacing water from the well but the surface pump is not delivering it, the issue could be with the surface pump itself. Common causes include damage to the pump, a broken check valve, or air trapped in the system.
Well Pump: If your well pump is making strange or unusual noises, such as grinding or vibrating, it could be a sign that the pump is failing or becoming clogged. This could indicate that the motor is under stress or the pump is encountering resistance.
Surface Pump: If the surface pump is making excessive noise, it could be struggling due to issues like airlocks, cavitation, or wear and tear. This might mean the pump is working harder than it should, potentially leading to failure.
Well Pump: Poor water quality, such as muddy or discolored water, could be a sign of submersible pump issues. If the pump has become damaged or has sucked in debris, it could be stirring up sediment in the well, leading to water contamination.
Surface Pump: While a surface pump usually doesn’t directly affect water quality, if it’s malfunctioning, it might be allowing air or debris to enter the system, potentially contaminating the water supply.
Well Pump: If your submersible pump is working inefficiently due to age or damage, it might consume more power to pump water, leading to higher energy bills.
Surface Pump: Similarly, if the surface pump is worn or malfunctioning, it may consume more electricity than usual, indicating a need for maintenance or replacement.
Well Pump: A submersible pump that runs continuously without supplying water or doesn’t start at all might indicate a failure in the pump motor or electrical connections.
Surface Pump: A surface pump that runs without effectively moving water or doesn’t start when it should could indicate issues with the pump’s motor, a clogged intake, or a malfunctioning control switch.
