To help identify the appropriate maintenance kit, review the pump head area around where the Lift Rod enters/exits the body. The pump heads manufactured during this period have the following characteristics:
- A brass Packing Gland Nut.
- Teflon Packing Gland Rope.
- The hex top plate is either threaded, soldered or welded onto the top of the pump body.
We no longer produce the brass Packing Gland Nut, and it is not included in this maintenance kit.
With this kit you will be able to replace most wear items to keep your Bison Pump running strong!
