Submersible water well pumps are a modern, efficient, and quiet solution for supplying your home with water well drinking water. The pump intake is set below the resting water level (static level) to allow the well's storage capacity to be maximized. A fitting is installed trough the well casing approximately 6 feet below ground surface, which allows the water line down the well to be attached to the underground waterlines. The fitting is accessible and detachable from surface, which allows the well casing to extend above ground level without the need for a well pit. This underground fitting makes this style of pump ideal for preventing possible contamination from common bacteria found in surface water, unlike jet pumps, which are generally work in conjunction with a well pit. A well pit makes your well vulnerable to contamination, water pools in the pit and usually finds a way into the well taking harmful bacteria with it. A jet pump system can be converted to a submersible pump, the well casing can be extended and the pit can be removed.
Grundfos 3" SQE Submersible Pumps
Grunfos SQE Model Pumps
Grundfos SQE model pumps are the preferred choice by Well Technicians in the water well industry. Grundfos SQE pumps are compatible with constant pressure systems as well as standard pressure systems, this versatile product allows for an immediate solution without compromising future development plans for your property. Grundfos offers a wide variety of models that are designed to suit specific water production and pressure demands.
Standard 4" Submersible Pumps
Franklin Electric 4" Pump
Submersible water well pumps were originally designed as a 4" diameter pump and are still in demand in the water well market. The pump and motor assembly is selected to suit the specific needs of your pressure system and water quantity demands. The most common and reliable 4" submersible pumps that we recommend are Franklin Electric, Berkeley and Grundfos, however there are many manufacturers that supply the water well industry with this style of pump.
Convertible Jet Pumps
Double and single line jet pumps are still very common but are slowly being phased out as they are generally considered "old technology". Jet pumps are usually found inside the house and draw the water from the well as opposed to pushing the water out of the well as a submersible does, this creates a loud noise inside the home every time your pressure system calls for water. There are some applications in which a jet pump may still be your best option, however, two line jet pumps are easy to upgrade and require little to no underground work in order to upgrade your system to a submersible style.
In order for a pressure system to function properly, it needs to be designed for your well specifically and how you want your home to function. Each water well produces water at a certain rate and not all pressure systems will work for your well. It is important to have your pressure systems sized by a professional, improper sizing can lead to substantial issues down the line. Designing the proper pressure system effects the lifespan of your water well, submersible pump, pressure tank, as well as other functions of your home that rely on the water supply.
Standard Pressure System
These are the most common pressure systems for country homes on water wells. The most important part of designing a standard pressure system is selecting the proper size of pressure tank. Pressure tanks come in a vast amount of sizes which can make this process difficult and can have an adverse effect on your submersible pump if sized improperly. The pressure tank acts as a buffer for how long your submersible pump is running for and how long it is off for. The idea is to have your homes running water pressure to cycle between 40 - 60 PSI, the submersible pump shuts off at 60 PSI and will not turn on again until the water pressure in the pressure tank drops to 40 PSI. The amount of rest time between the 40 - 60 PSI can be adjusted by selecting the right size tank, this allows your well to recover properly which reduces the chance of having problems with your water well.
Constant Pressure System
Not all water wells are compatible with constant pressure systems, these systems should only be used in conjunction with water wells that are capable of producing a large volume of water. These systems are designed to supply water on demand. For instance, if a faucet is turned on at a rate of 2 gallons per minute, the submersible pump will produce 2 gallons per minute as well, if another faucet is turned on and creates another 2 gallon demand, the submersible pump will increase the output to 4 gallons per minute to compensate for the increased demand. This system is the most economical and advanced option when selecting a pressure system. The system does not need the submersible pump to run at maximum speed to keep up with daily water demands, which in turn reduces wear on the submersible pump and reduces energy costs.
