The Grundfos CR Air-cooled Top pump is engineered to manage high-temperature liquids, ranging from 120°C to 180°C, without requiring external cooling. This proven design harnesses surrounding air for cooling.
Traditional pumps versus CR Air-cooled Top:
Standard pumps expose the shaft seal directly to the pumped liquid, leading to potential overheating and rapid deterioration, especially with hot liquids.
The air-cooled advantage:
The CR Air-cooled Top pump introduces a unique feature: an air-cooled chamber. This chamber acts as a protective barrier, dissipating heat from the hot liquid before it comes into contact with the mechanical seal.
Key benefits:
Maintaining a cool shaft seal, the CR Air-cooled Top pump offers numerous advantages:
Prolonged seal lifespan: Reduced exposure to high temperatures extends the seal's longevity.
Simplified installation and operations: the CR Air-cooled Top comes in a single set. Installation and operations are the same as a standard CR pump.
In essence, the CR Air-cooled Top pump is a standard Grundfos pump equipped with an integrated heat shield for the shaft seal, ensuring reliable performance with hot liquids.
