ARO CF-10 End Suction Pump for Data Centers

High Flow and Stable Pressure for Critical Data Center Cooling

The ARO CF‑10 End Suction Pump is a high‑capacity end suction centrifugal pump designed for demanding data center cooling applications. Engineered to deliver high flow with elevated head, the CF‑10 supports large closed‑loop cooling systems that require stable, continuous pressure.

Manufactured entirely from 316 stainless steel, this centrifugal pump for data center use offers excellent corrosion resistance and long‑term reliability in clean or lightly contaminated coolant loops commonly found in modern data center infrastructure.

 

Key performance highlights include:

  • Maximum flow: up to 148 m³/h (650 GPM)
  • Maximum head: up to 80 m (260 ft)
  • Fluid ports (inlet / outlet): 4" 300# ANSI x 3" 150# ANSI flanges
  • Material of construction: 316 stainless steel casing and components
  • Seal: Type 21 mechanical seal (carbon / ceramic / Viton)

The CF‑10 is designed for continuous operation and integrates easily into both new and retrofit data center cooling systems.

Engineered for Large Data Center Cooling Loops

The ARO CF‑10 End Suction Pump is part of ARO’s stainless steel centrifugal pump portfolio and is optimized for data center cooling applications where high flow rates and stable discharge pressure are essential. As data center cooling architectures scale, pumps must reliably move large volumes of coolant across extended piping networks without pressure fluctuation.

The CF‑10 supports these requirements through a robust hydraulic design that combines high flow capacity with elevated head capability. This makes it well suited for closed‑loop chilled water systems, distribution headers, and secondary cooling circuits in data center facilities.

The pump features an 8.0‑inch enclosed impeller, cast from 316 stainless steel, designed to deliver efficient hydraulic performance while maintaining consistent pressure. Multiple installation and drive options allow system designers to adapt the CF‑10 to the specific layout and operational needs of a data center.

Like other CF‑derived designs, the CF‑10 is not self‑priming and is intended for flooded suction installations, which aligns with standard mechanical room configurations in data centers.
