In 2018, the Eastern City Water Plant in South Africa found us through Google. Five sets of water supply systems need to be purchased. The customer needs to achieve constant pressure water supply in the urban area and ensure that the water supply can be guaranteed in the event of a power outage. We recommend to customers two types of pumps: electric drive and diesel drive. When the motor is sufficient, the electric drive pump is used for operation. When there is a sudden power outage, the system will switch to diesel pump operation in 5s-10s to ensure the real-time operation of the water pump. . At the same time, the customer used our self-developed wireless remote monitoring and detection system for smart pump stations, which can view various data on the operation of the pump station at any time and anywhere.
