1 151 GSGS SERIESSUBMERSIBLE PUMPSFOR 4 WELLSAPPLICATIONS Water supply. Sprinkler systems. Pressure boosting. Deliveryup to 21 m3/h. Head up to340 m. Maximum pump overalldiameter (cable coverincluded): 99 mm. Maximumimmersion depth: 150 m. Maximum permissible quantity of suspendedsand: 150 g/m3. 1 GSL - 2GS - 4GS - 6GS versions (radial impellers): 11/4 delivery port. 8GS - 12GS - 16GS versions (semi-axial impellers): 2 delivery port. Rated motorpower from to kW. Versions:Single-phase220-230 V or 230-240 V, 50 Hz, from to 380-415 V, 50 Hz, from to Overload protection to be provided by user andinstalled in the control box (see control box section).

2 -Maximum supply voltage variations: +6%/-10% Maximum number of starts per hour, at regularintervals: 30 (4OS motor), 20(F4 motor). Horizontal operation up to kW with 4OS or F4 seriesmotors, with F4 motor for higher powers. Maximum temperatureof water in contact with themotor:30 Abrasion resistant construction. The front wear plate,combined with the floating impellers, ensures optimumresistance to abrasion. The non-return valve is integrated in the head so as todischarge the weight of the column of water and anywater hammer onto the head itself, thussafeguarding impellers and diffusers.

3 The upper and lower supports are made ofprecision-cast stainless steel, ensuringresistance to corrosion, durability and a sturdycoupling to the motor. The GS SERIES pumps can be coupled to either4OS or F4 4OS motor characteristics, please see specificsection in this head,STAINLESS STEELV alve cap,(AISI 303 - DIN )Valve seatValve gasketNITRILE RUBBERV alve stop ringSTAINLESS STEEL(AISI 302 - DIN )Upper supportPOLYCARBONATE/FIBERGLASSB earingPOLYURETHANED iffuser, impellerPOLYCARBONATE/FIBERGLASSD iffuser case,Shim,Pump shaft,Outer sleeve,STAINLESS STEELS pacer,(AISI 304 - DIN )
