Dimensions And Order Information
NOTE 1 - Graymills uses "B" lengthto define the measurement from the bottom of the pump intake to the bottom of the optional C-32106 mounting flange at its highest position.
NOTE 2 - Intake of pump must be a minimum of 2" above bottom of tank.
NOTE 3 - Liquid level must always cover at least 5" of pump at all times. Graymills recommends installing a swing-type check valve to help pump hold fluid and prime easier.
