Description : 
Stainless Steel Vertical Multi-stage Pumps
The e-SV™ pumps are tough, efficient and built to last. Thanks to a unique combination of new hydraulic design and higher efficiency motor, the e-SV™ delivers lower overall life-cycle costs and superior efficiency compared to most pumps available today.

Multi-stage vertical pumps with impellers, diffusers and outer sleeve entirely made of 304 stainless steel, with pump body and upper head in cast iron in the standard versions (33SV-125SV) and 304 stainless steel (1SV-22SV). The N versions are entirely made of 316 stainless steel. This reliable and technologically advanced series owes its success to its flexibility of application, ease of maintenance, high performance and silent running.
