1. Overview

• Consist of technology to improve operation reliability and reduce maintenance cost of pipe system especially when leakage in piping system that occurs when pump is stopped suddenly in large pump station (ex. sewage system plant) due to water shock mitigation (steam cavities, shock wave from opening & closing valve, slam of check valve cause by backflow, surge cased by air pocket etc.)





2. Characteristics

• Non-Slam Ejector “F” and “R” technology is applied to the water shock mitigation device for the purpose reducing the pressure between the front and rear ends of the check valve as well as to delay the flow back immediately after the pump trip.

• It also alleviate the water shock(slam) that occur when the disc of the valve is closed and prevent Dead water in the tank by circulating fluid inside the tank using the Non-Slam Ejector “R”





3. Issuance Category (Effective Period)

• May 24th, 2018 ~ May 23rd, 2020
