Bison Pumps offers Stainless Steel Security Flange Bolts for use with flange installations on non-concrete surfaces or when joining two flanges. The bolts require a Security Flange Bolt Bit to install/remove.
Not all installations have the same bolt length requirements. Please contact us with your specifications. We have the dimensions for connecting our Model 1900 Stainless Steel Pitcher Pump to the Pitcher Pump Stand – Model 1900. For other installations for the Model 1900 or Flat Flange Deep Well Pump System, we would need to know the specifics of your project.
