FIELD: pumping devices.
SUBSTANCE: present invention relates to pumping and grinding device (1) including: at least one submersible pump (3) located in tank (2) suitable for receiving incoming material (5), and drive (4) designed to actuate submersible pump (3). In the specified device, at least one submersible pump (3) includes impeller (9) located in case (8) of the submersible pump, while case (8) of the submersible pump is equipped with suction nozzle (7) for suction of incoming material (5) into submersible pump (3). Tools (10) are located on the inner surface of case (8) of the submersible pump and (or) on impeller (9), thereby ensuring the grinding of solid particles contained in incoming material (5) by tools (10).
EFFECT: obtaining a pumping and grinding device.
