DAB S4 Pumps are robust submersible electric pumps capable of generating a broad range of flow rates and heads suitable for borehole installations.


Multistage centrifugal pump directly coupled to a submersible asynchronous two-pole motor made of AISI 304 stainless steel, for parts in contact with water. Pump-end incorporates techno-polymer impellers with stainless steel wear parts, functioning on floating clearance rings made of synthetic low abrasion material with techno-polymer diffusers that impart significant wear resistance to the pump. Pump liner, shaft and coupling, filter and cable cover in stainless steel. Base support and head in micro-cast AISI 304 stainless steel check valve incorporated in the delivery chamber.
