FIELD: engines and pumps.
SUBSTANCE: invention relates to pump production, particularly, to centrifugal self-priming pumps with pre-atomiser. The proposed pump comprises the housing with intake, delivery and pumping chambers, impeller, atomiser diffuser with its inlet communicating with the intake chamber and a nozzle. The latter communicates, via bypass channel, with the intake and delivery chambers. The said bypass channel accommodates an automatic locking gate valve with the gate comprising a permanent magnet or a ferromagnetic isolated from the working medium. The said magnet or ferromagnetic interacts with the opposite-polarity magnet isolated from the working medium and arranged in the housing aligned with the gate to axially move for adjustment the distance between the magnets of between the magnet and ferromagnetic with the valve in opened state.
EFFECT: higher efficiency, reduced time of suction.
