ASV Stübbe sump pump for aggressive fluids

The sump pump features closed impellers with vanes formed according to fluidic principles. The stainless steel shaft is separated from the fluid by a thick-walled thermoplastic tube, and the shaft lead-through is sealed at the mounting plate with lip seals. The two-part pump housing consists of the housing cover and pump housing, which are joined by screw connections. The new ETLB-E is available with drive ratings of 0.37 kW to 2.2 kW and can be currently supplied in polypropylene. The ETLB-F sump pump from ASV Stübbe is designed for heads of up to 21 m and has an immersion depth of 275 mm.

Applications for the ETLB-E sump pump include use in chemical plants, water treatment and electroplating, in pressureless containers, open basins or in pump pits.
