FE PETRO Sumbersible Turbin STP FE 3/4 HP Quality engineering and simplicity of the design work to ensure years of realible performance form every high capacity unit . The impellers made of moulded Derlin , and difussers of hard coated aluminium , with a stainless steel pump shaft , assure trouble-free operation in motor fuels. Dual (180Ëš opposed) 3" horizontal discharge ports provide easy insallation and two buil-in line check valve reduce insallation cost . Two lines pressure relief valves protect the dispensers , meters and piping from abnormal pressure due to thermal expansion. The mesh screen on the pump inlet prevents large particles from entering the unit and the unit is compatible with exsiting high capacity leak detector technology. New units are easily connected to field wiring without disassembly . Type : 3/4 Ho use if model length is 89-149" (228 CM to 373 CM) Use VL1 if model length is shorther than 86 down to 57" (218 CM to 114 CM) USe VL3 if model length is longer than 120 up to 205" (305 CM to 520 CM)
