The Bison Pumps Submersible Connection Deep Well Pump System is a Side-By-Side Deep Well PumpΒ that installs in the same well casing as your electric submersible pump system. It is NOT a Freeze Proof pump system due to the water from the electric submersible pump exiting the well above ground. It 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. This pump system is recommended when there is sufficient space inside the well casing and the water from an electric submersible pump system exits above ground.

Wires from your electric submersible pump 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 adapter. Bison offers a conduit system for either approach:Β Conduit El – Top MountΒ orΒ Conduit El – Side Mount.

Additionally, to further protect your investment, we can add a Tamper Proof KitΒ 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 Submersible Connection Deep Well Pump System comes with enough eight (8) foot sections ofΒ Drop Pipe and RodΒ 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 surface. The size of the Drop Pipe is typically 1 1/4” but we do offer and recommend 1” for certain applications. This would be where 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 Submersible Connection Deep Well Pump system. In aΒ Lift Pump system, like the Side-By-Side Submersible Connection, the actual β€œpump” is the cylinder. 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 this Standard Cylinder Selection Chart to determine the appropriate size for each customer’s situation.

Typically, Bison Pump Deep Well Pump Systems can be installed by two handy people without the need for a professional. However, a Submersible Connection system is different from the typical system. First, the electric submersible pump system must be suspended while the Bison Pumps system is installed (or removed completely). This normally requires access to equipment that a homeowner does not have. Additionally, there will be interruptions in the water line that feeds the owner’s home. Therefore, we strongly recommend a professional installation for this type of pump system. For a professional installation, you can contact one of our many dealers across the country.
