SATURN are primary pumps made of Fiberglass which offer high mechanical strength, dimensional stability and excellent chemical resistance. They are perfectly fitting for various applications with corrosive fluids in industrial processes or wastewater treatments for example. These pumps are made in accordance with ANSI/ASME B73.1, in versions with mechanical support, base and coupling to the motor and close-coupled to the engine with specific support bearing.


Since more than 7 years now Argal uses one of the strongest and most resistant material for producing reliable and high-quality pumps. The thermoset Fiberglass Reinforce Plastic (FRP) is well-known in the pump industry for its low weight, robustness and unbeatable properties. Fiberglass characteristics are now widespread but this is not the case for the realisation technique we use: the Resin Transfer Moulding (RTM) process. 

Advantages of Fiberglass material 

The FRP is a thermoset plastic hardened into a given shape by catalysis. This irreversible reaction modifies the polymer by creating a three-dimensional structure, a higher degree of robustness and by increasing its chemical and mechanical properties: lightweight, higher mechanical strength, higher chemical and corrosion resistance, longer life cycle, lower maintenance need as well as thermal stability. 

Thanks to is technical features, FRP is excellently suited for use in chlorine and saltwater. Indeed the combination of mechanical strength and its corrosion resistance (without any additional coating required in the steel processing) makes it the best material to use for centrifugal pumps into water and wastewater facilities. Fiberglass material is a cost-effective and lightweight material with a greater strength to weight ratio than steel (see sideline the table of comparison).
