SERIES S PRESENTATION
The new submersible electric pumps of a mixed-flow type far 6" 8" 1 O" wells consist of a modular set of components, which allows the performance of high capacities with medium working heads. The pump bowls, made of cast iron, contain the direction blades. The mixed-flow impellers, dynamically balanced and locked on the shaft by conical bushes are made of cast iron or bronze on request. The pump shaft, in hard-chromed carbon steel, is supported by rubber bearings at each intermediate bowl and by a bronze bearing located inside the suction bowl. The latter, made of cast iron, allows the coupling between pump and motor, and protects the shaft coupling. The delivery bowl made of cast iron has a threaded or flanged end and houses the closing non-return valve.
The submersible motor is produced by renowned companies worldwide according to high manufacturing quality standards. The specific size in compliance with "NEMA" standards allows a quick coupling and easy exchange.
