Answer: ①, ISG single -stage single -stage single -suction centrifugal water pipe pump. It is used for industrial and life -supply drainage, high -rise buildings, water delivery, heating, refrigeration and air -conditioning circulation, industrial pipelines to transport and clean, and provide water equipment and boilers. Use temperature ≤80 ℃.

② IRG single -stage single -stage single -absorbing water pipe pipe pumps are used for metallurgy, chemical, textiles, wood processing, papermaking, and hotels, bathrooms, hotels and other departments, high -temperature hot water pressure pressure voltage circulation, and use temperature ≤120 ° C.

③ The pump of IHG single -stage single -stage suction chemical pipeline is used for chemical corrosive liquids in industrial transportation, oil, chemical, medicine, hygiene, food, refining and other industries. Use temperature ≤100 ° C. It is an ideal product to replace the conventional chemical pump.

④, YG -type single -grade single -absorbing pipe oil pump. It is an ideal product for conventional oil pumps. Applicable to the oil depot, refinery, chemical industry and other industries, as well as the power departments of enterprises and institutions to transport oil and flammable and explosive liquids, and the use temperature ≤120 ° C.

⑤ The GRG, GHG, GYG single -stage single -stage single -suction high -temperature pipe pump High -temperature pipeline pump was formed by designing an increased water -cooled cooling device on the basis of a normal type. The use temperature ≤185 ° C, and the range of use is similar to the normal type.
