Pumps for maritime and nautical sectors


ARGAL pumping solutions for seawater fit maritime and nautical sectors’ needs perfectly, solving the issue of transferring corrosive liquids, acids and waste. 

Centrifugal and air-operated pumps made of composites, metals or plastic, we offer a complete corrosion-free range for the transfer of seawater, ballast, brine, waste water, refrigerants and others. 


The main liquids pumped in the maritime and nautical sectors are: 

  • Seawater with temperature between 20 and 25°C mainly for aquaria, aquaculture, theme parks and all pools that need an unalterated medium for the basins 

  • Fresh water, cold water depending on the flora and fauna for aquaria, pools

  • Dry bilge water and brine

  • NaOCl (sodium hypochlorite) for continuous dosing, shock-dosing within desalination and electrochlorination processes

  • Refrigerant mainly for boat-cargo-yacht cooling systems


ARGAL provides a complete range of solutions for the above liquids and applications, respecting the requirements and needs for any process and system. 

πŸ‘‰ Air-operated double diaphragm pumps

  • ASTRAevo (ideal for dry bilge system, the series is available from size 1/4" to 2" and the recommended material is Aluminum with aluminum center block) 

  • ​QUANTUM (ideal for gentle transfer, like plankton transfer, the series is available in two sizes 1/2" and 1 1/2" and the recommended material is Ultra High Moleculare Weight Polyethylene - PE1000)

πŸ‘‰ Magnetic centrifugal pumps

  • BASIS and PRIMA series (mainly installed for cooling systems, the series offer close-coupled compact version with leakage and vibration-free)

  • ROUTE and RHINO series (available in Polypropylene and E-TFE, both series ensure seawater, acids and waste circulation. ROUTE series is also available in mechanical sealed version and RHINO series self-prime up to 6m length) 

πŸ‘‰ Fiberglass (FRP) centrifugal pumps

  • SATURNevo (entirely made of special Vynilester resin, the renowed series ensures an excellent corrosion and high abrasion resistance.
    Thanks to the use of Kevlar for feet and flanges or carbon-filled FRP for the impeller, the pump general resistance is improved for a longer life cycle and less maintenance costs and operations. The series is also available in compact and sump version) ​​

πŸ‘‰ Sump pumps

  • K2 (thermoplastic vertical sump configuration with 4-meter-length column reinforced with fiberglass for better resistance to corrosion, abrasion, thermal changes. It is ideal for seawater and wastewater treatments)  


Here's a short reel of the practical applications of these pump ranges related to maritime and nautical markets.
