Bac Cooling Tower Pump

When you mention BAC cooling tower pump, you’re usually referring to the circulation pump or condenser water pump that works together with a Baltimore Aircoil Company (BAC) cooling tower. The pump is not part of the tower itself (BAC mainly manufactures cooling towers, condensers, adiabatic coolers, etc.), but it’s an essential part of the system.

Here’s a BAC cooling tower pump breakdown for you:

Role of the Pump in a BAC Cooling Tower System

1. Water Circulation – Pumps move warm condenser water from the heat source (like chillers, compressors, or process equipment) to the cooling tower.

2. Distribution – Pumps ensure the water reaches the cooling tower spray nozzles, where it is evenly distributed over the fill media for efficient heat rejection.

3. Return Loop – After cooling, the pump drives the water back to the equipment to absorb heat again, completing the loop.

Common Pump Types Used with BAC Cooling Towers

End Suction Centrifugal Pump – Most common; simple design, installed close to the cooling tower basin.

Vertical Inline Pump – Space-saving, often used in mechanical rooms with vertical piping.

Vertical Turbine Pump – Used if the cooling tower basin is very deep or if sump pumps are needed.

Split Case Pump – Suitable for large tonnage cooling systems where high flow is required.

Key Pump Selection Considerations

Flow rate (GPM or L/s) based on tower tonnage and system design.

Head (m or ft) to overcome piping, fittings, and tower elevation.

Material (cast iron, stainless steel, bronze) depending on water quality and treatment.

Efficiency for energy savings.

Compatibility with VFDs for variable load operation.

Pump & Tower Integration

BAC often provides piping guidelines and recommended pump locations in their installation manuals.

Pumps are typically located at the cold-water basin discharge (suction line) of the tower.

For open-loop systems, pumps must handle water with potential scaling and biological fouling, so proper water treatment is critical.
