The Endurance series by Caprari consists of a range of electric pumps which are suitable for use in heavy duty conditions with brackish, aggressive, sandy and marine waters. These products are made using a stainless steel, which can be efficient when combined with Caprari's design systems. The thick steel and absence of welding is designed to increase the pump’s abrasion resistance, as well as lowering the friction and turbulence.
Corrosion resistance
This latest electric pump aims to provide greater savings compared to competitors. It is also possible to achieve performance curves centred on the duty point with specific impeller trimming. All components are made of AISI 316 stainless steel, which guarantees high corrosion resistance (40,000 parts per million of T.D.S. - Total Dissolved Solids). The shaft and joint are made of duplex for more reliability in aggressive environments. The feather key seat on the shaft end has been eliminated, increasing the component resistance thanks to the transmission through splines. The Endurance electric pumps are designed to withstand galvanic corrosion thanks to the Defender system which protects the machine. Endurance electric pumps are suitable for applications with solid content up to 150 g/m3. They feature bearings with anti-recirculation lip which can protect against sand. The Protector device, installed in Nema couplings between the wet-end and motor, seals the area, protecting the coupling and preserving the motor mechanical seal against solid substances.
