Use the Standard Deep Well Pump System if your well specs meet one of these scenarios:
|Static Water Level:||250′ or less|
|Electric Submersible Pump Installed:||No|
|Well Casing Outside Diameter:||4″ or less|
|Static Water Level:||250′ or less|
|Electric Submersible Pump Installed:||Yes|
|Well Casing Outside Diameter:||5″ or more|
|Water Exits Well Through:||Pitless adapter|
The Bison Pumps Standard Deep Well Pump System is a Side-By-Side system that installs in the same well casing as your electric submersible pump system. It is a Freeze Proof pump system that can deliver you with Pressurized Backup Water when used in conjunction with the Pressurizing System. This provides you with water inside your home accessible to any water feature such as a toilet or sink! It can lift water from 250 feet deep using the standard handle or up to 300 feet with the addition of the Heavy Duty Pump Head option. The Standard Deep Well Pump System is recommended when there is sufficient space inside the well casing and the water from an electric submersible pump system exits underground.
The Bison Pumps Side-By-Side Deep Well Pump System with the Standard Deep Well Pump Adapter welded on is used for the vast majority of pump systems. This system applies to cased wells either with no electric submersible pump installed or, if one is installed, it uses a pitless adapter to exit the water from the well. Most, but not all, of the wells look like the one below before installing the Bison Pump. The pitless adapter must be one that hugs the inside of the well casing similar to the one in the photo below. Some pitless adapters consume all of the space available inside the well casing as seen in the photo below. If that is the type of pitless adapter that you have, then it must be replaced with the other style in order to install a Bison Pumps Side-By-Side Deep Well Pump System.
Well Pump Adapter
This system works with well casing diameters from 4” up to 8” (special order above that size). However, if the well has an electric submersible pump installed and the well casing is less than 5” in diameter, in most cases the Standard system will not fit inside the well casing. In those cases, we recommend one of our Stacked Deep Well Pump Systems.
This well pump adapter replaces your well cap and provides a seal to protect your well water from contaminants. The adapter has one 3/4” NPT threaded port for wires from an electric submersible pump to exit the well. Another port, 1/2” NPT (3/4” if pump is installed in Michigan) is for the Vent Plug. There are four bolt holes for the bolts that hold the bottom plate kit to the well pump adapter.
The bottom plate kit provides the seal for the well. It consists of a rubber gasket and stainless-steel bottom plate. The rubber gasket is compressed by the bottom plate when the four bolts that are attached to it and the well pump adapter are tightened. This gasket can expand up to 1/4” to create a seal. Therefore, we must resize the gasket for every 1/4” change in the inside diameter of the well casing. This is why it is so important to provide us with an accurate inside diameter measurement.
Wires from your electric submersible pump, if you have one, must exit the well. They can exit through the side of the well casing if permitted in your area. If not, then the wires can exit through the port hole provided in the top of the well pump adapter. Bison Pumps offers a conduit system for either approach: Conduit El – Top Mount or Conduit El – Side Mount.
Each well pump adapter covers a range of outside diameters of the well casing. For example: the 6” covers from just below 6” to just over 7” in diameter. Four all-thread Socket Set-Cup Points with Covers are provided to address these size differences. When the well pump adapter is mounted to the well casing, you will thread the bolts through the four holes provided in the side of the adapter. These will apply pressure against the well casing, providing more stability for the pump head. Plastic covers are provided to protect the all-thread Socket Set-Cups.
Additionally, to further protect your investment, we can add a Tamper Proof Kit to this style of well pump adapter. The adapter will be connected directly to the well casing with security bolts. This system protects against unwanted removal of the pump head.
Drop Pipe and Rod
Each Bison Pumps Side-By-Side Standard Deep Well Pump System comes with enough eight (8) foot sections of Drop Pipe and Rod to reach approximately 20 feet below the static water level. This depth allows for fluctuations in the water table and ensures that the cylinder will be below the water’s surface. The standard size of the Drop Pipe is 1 1/4” but we do offer and recommend 1” for certain applications such as when the inside casing space availability is a concern, or the static water level exceeds 160 feet.
Note that the deeper the static water level is, the more drop pipe will be required. This directly impacts the cost and design of the system. This is why a fixed cost for a pump system cannot be provided. Each pump system is unique to the customer’s well specifics.
One appropriately sized cylinder is included in a Side-By-Side Standard Deep Well Pump System. In a Lift Pump system, like the Side-By-Side Standard, the cylinder is what lifts the water. This is the device that creates the vacuum to draw water into the water inlet and then uses its piston assembly to lift the water up the drop pipe. In a Side-By-Side application, the size of the cylinder is determined by space available inside the well casing and the static water level. We use the Standard Cylinder Selection Chart to determine the appropriate size for each customer’s situation.
