FIELD: pumps.
SUBSTANCE: group of inventions relates to molten metal transfer pumps. Pump for molten metal comprises an elongated tube of fibre reinforced material having a lower end limiting the inlet and an upper end limiting the outlet. Inside the pipe there is a shaft, to which an impeller installed near the lower end is attached. Pump has support ring of reinforced material located in inlet.
EFFECT: inventions are aimed at creation of compact strong pump, having light weight reduced by scale formation, easy access for cleaning, forms equilibrium vortex at low speeds of impeller rotation.
