The Bison Pumps 2” Threaded Deep Well Pump System is a Stand-Alone system that functions the same as the Side-By-Side Deep Well Pumps but is not installed in the same well casing as your electric submersible pump system due to a lack of available space inside the casing. 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. It is recommended when the well casing is 2” NPT and there is not an electric submersible pump system installed in the well.

Drop Pipe and Rod

Each Bison Pumps Stand Alone 2” Threaded 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.

Note that the deeper the static water level is, the more drop pipe and rod 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 1 1/2” cylinder is included in a Stand Alone 2” Threaded Deep Well Pump System. In aΒ Lift PumpΒ system, like the Stand Alone, 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. When installing the 2” Threaded Deep Well Pump System, the only cylinder that would fit inside the well casing is the 1 1/2” diameter cylinder. It outputs a gallon of water for roughly every 32 strokes.
