This maintenance kit is for our most recent model of the Model 1900 Stainless Steel Pitcher Pump with the Drain Back Feature. To verify this kit is for your pump, identify how the Rod Connector is secured to the Lift Rod. Our current models use a Shoulder Screw (tight tolerance shoulder to reduce wear) to attach the Rod Connector to the Lift Rod.

This kit does not include the Drain Pin Removal Tool used to reach the bottom of the inside of the pump body. A socket extension with a 1/2” socket may work. Note that the Drain Pin Removal Tool has a special rubber insert in the socket to prevent dropping the Drain Pin during removal. This tool is available for purchase separately.

With this kit you will be able to replace all wear items and some hardware to keep your Bison Pump running strong!
