[INQ. NO. 2306E08] The submersible pump is designed to optimize the structure of the impeller as a single channel type (S-tube type) of pump for the treatment of wastewater discharged from various areas such as the home and industrial field.
The operating range is wider and the vibration is lower than that of other submersible pumps for transfer, so the efficiency is relatively high. It is possible to transport wastewater containing solids or heavy concentrated sludge, and to safely transport fruits or young fishes without damage.
With the pump fault prediction, the temperature of the motor and leakage inside the motor are checked.

Ring blower
The ring blower is a machine used in various industrial fields that require the power of high-pressure air and is known as a regenerative blower. It is designed and manufactured in various sizes and structures depending on usage and performance. It is a fluid machine that produces high pressure air with a low flow rate.
There are two types of ring blower — single and double ring blowers — according to the number and shape of the impeller. The single ring blower compresses air once with one impeller, while the double ring blower compresses air twice with two impellers.

Hwanghae Electric Co., Ltd is achieving successful results by conducting continuous technological cooperation and research and development with leading domestic and foreign research institutions and universities. In addition, it has developed its own design/analysis capabilities using the latest design programs and fluid analysis programs of industry-academia institutions, combined with its considerable field experience, and its technology is also positioned at the highest level.
As a result, it has a 40% share of the domestic market, in the ring blower industry, and has established sales offices in more than 50 countries around the world, including the United States, European countries, and Japan, and continues to actively export its products.
Hwanghae Electric always strives to provide the best quality, while developing new models that can meet the needs of customers through constant research and development, and makes products that can be safely used in various environments.
