Fiberglass pumps were presented by Affetti 2 years ago. In these few months the success of these pumps have overpassed the expectations and the success of our products is confirmed by our most important customers.Desalination, Aquarium and electro-chlorination are the most important application.
Affetti design is made to give new important features in order to guarantee a concrete lifetime of the pump. No-screwing impeller is just an example of our past experience in thermoplastic pumps. A docking system composed by an internal impeller nose with a nut drowned, counter-nut and a washer avoid the impeller screwing form the shaft in case of reversal sense of rotation during the start.
All our fiberglass pumps are made by Vinyl ester resin with strand fiberglass mat reinforcement with addition of short & long fiberglass pieces to guarantee the compactness.
Casing after the moulding process are hydrostatically (up to 14 bar for some sizes) and mechanically tested. Our FRP pumps are internally and externally gel-coated to guarantee UV protection and better fluid dynamics properties. Pumps are available in ANSI/ASME B73.1 design and in DIN EN 22858/ISO 2858 on special request with shaft adjustment system in order to guarantee the same performances even after long period of use. Shaft sleeve is separted from the impeller allowing its replacement in damage case, without removing the impeller, for a saving spare parts costs.
