Bison Pumps are designed to share the same well casing as an electric submersible pump. Therefore, most wells that have a Bison Pump system also have an electric pump with wires feeding the pump for power. These wires can access the well through the top of the well adapter. In these cases, Bison Pumps offers a solution for encasing the wire in conduit, Conduit El – Top Mount. This unit is threaded into the access hole pre-drilled into the top of the well adapter. If your wires access the well casing through the side of the casing wall, then see our Conduit El – Side Mount.
