Radial Multistage Submersible Pumps 

The EM series submersible electric pumps (for wells with a nominal diameter of 8") are radial, with cast iron diffusers and impellers, with external stainless steel tie rods.

There are 4 types of impellers, with only 2 types of diffuser. This allows for easy management of dismantled pumps and spare parts. They also have the peculiarity of having the hexagonal guide shaft for easy maintenance.

The guide bushings are made of rubber, coupled with thick chrome-plated bushes for continuous operation in harsh conditions, particularly suitable for heavy sand.

The use can be continuous.

The impeller wear rings are made of rubber (6 "and 8") or bronze (10 "and 12").

B10 bronze impellers are possible.

The couplings are all normalized according to NEMA, 6 and 8 standards.

The direction of rotation is counterclockwise, seen from the outlet.

The uses are for clean and non-aggressive water, in particular: withdrawals from deep wells for domestic and industrial use, lifting water systems, sliding or rain irrigation systems, aqueducts, pressurizations, fire and washing systems, autoclave power supplies and tanks.
