  • Publication number: 20210123455
    Abstract: A high-powered sanitary pump includes an impeller (20) axially mounted inside a case (10) and rotating by a motor (M) in order to inhale and discharge fluid by a rotational centrifugal force of the impeller. The impeller (20) has discharge pipes (22) radially connected to the cylindrical inhalation groove part (21) so as to be able to run at low noise and at low vibration and provide high performance with high pump-up head and flow rate while inhaling and discharging fluid not by forced pressure that forcedly pushes the fluid by a conventional rotor blade but by pressure inducing a gentle flow, by high pressure or by vacuum pressure.
