ARO CF-300 End Suction Pump for Data Centers

High‑Flow, High‑Pressure Cooling for Large Data Center Circuits
The ARO CF‑300 End Suction Pump is a heavy‑duty centrifugal pump designed for demanding data center cooling applications requiring higher flow rates and stronger pressure. As part of the ARO CF Series, the CF‑300 supports continuous duty in large cooling circuits where thermal stability and reliability are critical to protecting servers and network infrastructure.

Engineered with a stronger cast iron body and stable pressure curves, the CF‑300 is well suited for circulating warmer liquids and managing higher hydraulic loads. This end suction centrifugal pump delivers smooth, consistent performance in mission‑critical data center environments where uptime cannot be compromised.

Key performance highlights:

Maximum Flow: up to 118.1 m³/h (520 GPM)
Maximum Head: up to 58 m (190 ft)
Fluid Ports (Inlet/Outlet): 3" x 2.5"
Material of Construction: Cast iron with stainless steel fasteners
Maximum Solids Handling: up to 11.9 mm (0.47 in)
Motor Power: up to 15 kW (20 HP)

Built for reliability and long service life, the CF‑300 delivers the performance required for modern data center cooling systems operating around the clock.

The ARO CF‑300 End Suction Pump is an end suction centrifugal pump dedicated to data center cooling loops with higher flow and pressure demands. Cooling pumps play a central role in a data center by moving chilled liquid through advanced thermal management systems. The CF‑300 ensures stable circulation to help prevent overheating and maintain optimal operating conditions for critical IT equipment.
Designed for larger circuits, the CF‑300 combines hydraulic efficiency with mechanical robustness. Its enclosed impeller design improves efficiency and bearing life, while the cast iron construction supports long‑term use in demanding data center environments.
