The GB-414 Series™ DIR is a rebuildable pipeline injection pump engineered as a direct drop-in replacement for the Northern® 4900 Series. It matches existing motor, base, and piping dimensions, and its dual SAE and 2" NPT ports eliminate costly piping modifications. It handles flows up to 136 GPM, with a field-rebuildable design that restores the pump to as-new condition.
