Deep well pumps have largely replaced centrifugal pumps due to the drop in groundwater level. Now there are more than 9000 simple deep-well pump more than Taiwan, the vast majority of 170JS50 ~ 30 type. The pump rated speed of 2300 rev / min, the corresponding design flow of 50 meters to 3 / hour, lift 32 meters, supporting power of 7.5 kilowatts
