Taco 1/25 Hp Cast Iron Pump, 0-14 Gpm review

THE TACO 008F CAST IRON FLANGE PUMP WAS INSTALLED TO LOWER THE TEMPERATURE OF THE SOLAR COLLECTOR TO HEAT EXCHANGER GLYCOL THERMO-SYPHON LOOP. AT PEAK OUTPUT IT LOWERED THE TEMP FROM 180 DEG F.TO 110 DEG F. THIS 64 SQ. FOOT COLLECTOR AREA SOLAR SYSTEM HEATS 80 GALLONS OF WATER 8 DEG.F. OVER THE 3HR MAX SUN PERIOD. THE TUBING IS TWO 60 FT. LONG 3/8 IN COPPER TUBING COLLECTORS IN PARALLEL AND A SINGLE 60 FT. 3/8 IN COPPER TUBING HEAT EXCHANGER COIL. A 5 PSI DIFFERENTIAL PRESSURE AT THE PUMP INLET AND OUTLET EQUATES TO 11.5 FT. H2O HEAD OR 7 GALLONS PER MINUTE FLOW. THE PUMP DID THE TRICK AS FAR AS I CAN SEE. I WASN'T SURE WHICH PUMP TO GET SO I CHOSE THE 008F MODEL BECAUSE OF IT'S HIGH HEAD CAPABILITY.
