FX6-8

SUBMERSIBLE WELL PUMPS

The FX series submersible electric pumps are of the semi-axial type and are available in cast iron or AISI 316 stainless steel. The FX series, in 6” and 8” borehole diameters, features a single diffuser and four different impellers for each type. This allows easy management of disassembled pumps and spare parts, and also makes assembly by customers possible using practical kits.

The shaft is hexagonal and entirely covered with ceramic-coated steel sleeves. The guide bushings are made of rubber for continuous operation under heavy-duty conditions, particularly suitable for high sand content. Continuous operation is possible. The impeller wear rings are made of special rubber. All couplings are standardized according to NEMA standards, 6” and 8”. The discharge outlet can be threaded or flanged on request. The direction of rotation is counterclockwise when viewed from the discharge outlet.

They are suitable for clean and non-aggressive water, in particular: deep well extraction for domestic and industrial use, water lifting systems, surface or sprinkler irrigation systems, aqueducts, pressurization systems, fire-fighting and washing systems, and supply to pressure tanks and cisterns.
