Abstract

본 발명은 급수량이 많은 영역에서는 부스터에 의하여 급수량이 적은 영역에서는 가압 탱크에 의하여 급수를 수행하는 가압식 급수 펌프장치에 관한 것으로, 고가 수조에서 급수의 오염 및 건축물 구조상의 단점 등을 보완하고 운전시 에너지의 소비량을 줄여 모터의 기동과 정지를 최소화할 수 있는 우수한 효과를 갖는다.The present invention relates to a pressurized water pump device that performs water supply by means of a booster in a region where a large amount of water is supplied by a booster. By reducing the consumption of the motor has an excellent effect to minimize the start and stop of the motor.
