It mainly depends on your specific application ~ Gryffindor (Denmark): Small cold/hot water circulating pumps account for more than 50% of the global share, vertical multistage pumps and stainless steel deep well pumps are also strong points, and there is a complete distribution and service network in China; Others are sewage pumps and pumps for machine tools, which have a relatively large market share; Willard (Germany): The strength is similar to that of Gryffindor, such as small circulating pumps and stainless steel pumps, but the scale is much smaller and the service in China is relatively weak. ITT Group (USA): The strength is Feili's sewage pump series, the largest manufacturer of submersible sewage pumps, and the imported FM/UL fire pump series also accounts for a large share. The Group has other businesses besides pumps; Kesby Kesby (Germany): Germany's advantages lie in the power generation industry and power plants. It is the first pump brand in the power industry. There is a joint venture factory in Shanghai, mainly casting pumps, which are suitable for high temperature and high pressure. There are many pumps for seawater desalination now. Pintel Pentair (USA): This group is mainly engaged in water treatment equipment, pumps and swimming pool equipment. The group has many brands. The famous pumps are Aurora air conditioning pump and Meyer piston pump, and the market share of FM/UL fire pump is also relatively high. Its subsidiary Fairbankmorse is said to be the second largest sewage pump manufacturer in the United States. Unlike ITT sewage pump, it is mainly dry, and there are few domestic application cases. Ebara (Japan): It is one of the top ten manufacturers in the world. In the past two years, it has been widely promoted in China market, but as far as pumps are concerned, it has not been successful in China market recently. Franklin: Strictly speaking, it is not a water pump brand, but a submersible motor. It is the world's largest manufacturer of deep-well submersible motors, and recently started to produce deep well submersible pump. There are too many brands of water pumps, that's all I'll say ~
