Air Conditioning Pumps: Circulation is Key


Marine air conditioning pumps are the heart of your boat's cooling system. Without proper seawater circulation, the compressor and heat exchangers risk overheating, leading to costly damage. That's why it's crucial to choose a pump that's right for the size of your system and the operating conditions.


Self-priming models, such as those from CEM Elettromeccanica and Marco, are particularly well-suited due to their ability to draw water even in the presence of air bubbles. This is a significant advantage in rough seas or when the seacock is not fully submerged.


Always verify the flow rate (liters per minute) and the head (meters) of the pump. An insufficient flow rate will not guarantee adequate cooling, while a head that is too low may not be sufficient to push water through the entire circuit.


Remember to periodically check the replacement filter to prevent impurities and debris from compromising the pump's efficiency. A clean filter ensures greater durability and optimal performance.


Nautica Basile's Advice



  • Fast and secure shipping throughout Italy.

  • Official manufacturer's warranty.

  • Pre- and post-sales technical assistance.

  • Original spare parts available in stock.


An extra tip? Pair your pump with a good Y-strainer to protect it from debris and algae. And if you have a generator, consider installing an inverter air conditioner for even greater comfort.


How do I choose the right pump for my marine air conditioner?


The choice depends on the power of the air conditioner (BTU/h) and the length of the hydraulic circuit. Consult the manufacturers' compatibility charts (e.g., Osculati) or seek advice from a qualified technician. Also, consider the supply voltage (12V, 24V, or 230V) based on your boat's electrical system.


How often should I replace my air conditioning pump?


The lifespan depends on the hours of use and the quality of the seawater. Generally, a well-maintained pump can last several years. However, it is advisable to carry out an annual inspection and replace the pump every 5-7 years, or sooner if you notice performance drops or abnormal noises.


Can I use a bilge pump for air conditioning?


No, bilge pumps are not suitable for air conditioning. AC pumps are designed for continuous operation and to withstand high temperatures. Bilge pumps, on the other hand, are designed for occasional use and have a lower head.


What products should I use to clean the air conditioning cooling circuit without damaging the components?


Use specific products for cleaning marine cooling circuits that do not contain aggressive acids or solvents. Carefully follow the manufacturer's instructions and rinse the circuit thoroughly after cleaning. Avoid using generic household cleaning products, which could damage seals and hoses.
