Abstract
A gas seal column apparatus includes a pump drive motor, a gas seal column, a pump system, a level sensor, and a control box. The gas seal column receives a seal gas for pressurizing the gas seal column. The pump system includes a pump and the gas seal column. The pump system is coupled to the pump drive motor and moves a product through the pump. The level sensor is supported on a sensor column that is separate from the gas seal column to detect a level of the product in the gas seal column and any fumes in the gas seal column. The control box is in communication with the level sensor and controls the seal gas received within the gas seal column and the sensor column to control an amount of fumes and the level of the product within the gas seal column.

A gas seal column apparatus comprising:
- a pump envelope including a gas seal column and a pump;
- a pump drive motor configured to drive the pump envelope, the pump envelope and the pump drive motor configured to be sealed together;
- a drive shaft encased by the pump envelope between the pump drive motor and the pump to couple the pump drive motor to the pump;
- a sensor column that is separate from the gas seal column;
- an inlet pipe configured to receive pressurized seal gas for introducing the seal gas into the sensor column and the pump envelope;
- and
- a discharge valve configured to enable the seal gas to exit the pump envelope.
A gas seal column apparatus, comprising:
- a pump drive motor;
- a gas seal column configured to receive a seal gas for pressurizing the gas seal column;
- a pump system comprising a pump and the gas seal column, coupled to the pump drive motor and configured to move a product through the pump;
- at least one level sensor supported on a sensor column that is separate from the gas seal column to detect a level of the product in the gas seal column and any fumes in the gas seal column;
- and
- a control box in communication with the at least one level sensor, the control box configured to control an amount of the seal gas received within the gas seal column and the sensor column to control an amount of fume and the level of the product within the gas seal column.
