Pumpes à eau de refroidissement
A horizontal split-case centrifugal pump engineered for the high flow and moderate head required between chillers and cooling towers.
- High-Flow Double-Suction Design
- Balanced Axial Loading
- Split-Casing Access
- Heavy-Duty Bearing Support
Introduction de produit
The cooling-water pump uses a horizontally split cast-iron casing around a double-suction impeller. Water enters both sides of the impeller, reducing axial thrust and supporting large condenser-water flows with stable bearing loads. The upper casing half can be removed to inspect the impeller, wear rings and shaft without separating the lower casing from the main pipework.
Key Features
A double-volute casing balances radial forces through a broad operating range.
The horizontal split line exposes internal wear components while suction and discharge flanges stay connected.
Independent bearing housings and a rigid base suit continuous cooling-tower circulation duty.
Préoccupations du client produit
Condenser-water pumps must carry large flow continuously while tolerating treated water and service interruptions.
High inlet velocity causes cavitation and unstable vibration.Double-suction entry shares flow between two impeller eyes and improves suction behavior.
Large impellers generate high radial and axial bearing loads.Balanced double-volute and double-suction geometry reduces shaft loading.
Inspecting a conventional volute requires cutting connected pipework.The removable upper casing exposes the rotating assembly while lower flanges remain installed.
Cooling-tower water attacks unsuitable internal materials.Coated cast iron, bronze or stainless wear components can be selected for the treatment program.
