FIELD: motors and pumps.
SUBSTANCE: rotary fish pump 1 comprises a cylindrical housing 8 with a suction 10 and delivery 11 nozzles, a rotor 17. The cylindrical housing 8 consists of two compartments in the form of vertically truncated circular cylinders. The cylinders abut with their truncations to the vertical dividing partition 9. Along the line of the dividing partition 9 to the housing 8 the suction 10 and delivery 11 nozzles are embedded. In each compartment of the cylindrical housing 8 the rotors 17 are eccentrically placed. The rotors 17 are made in the form of circular hollow cylinders with a vertical shaft 18. One rotor rotates counterclockwise and the other - clockwise. In the gap between the rotor generator 17 and the input end of the delivery nozzle 11, a sealing device in the form of a cylinder 23 with a vertical shaft 24 is mounted. The side surface of the rotors 17 can be covered with a film, such as a rubberised material. The sealing device can be manufactured, for example, from soft rubberised material.
EFFECT: increased efficiency of operation of fish pump and reduction of damage to fish.
