FIELD: processes related to crystal growing from solutions, possibly high-speed growing of profiled crystals.
SUBSTANCE: rotary axial pump includes rotor and housing made of chemically stable material and having inlet windows, inlet and outlet separators and at least one nozzle for guiding solution. Housing is in the form of one non-detachable member with separators having radial plates. Rotor is made in such a way that it includes no more than two parts of chemically stable material while number and size of blades of rotor spiral correspond to dimensions of sections of inlet separator of housing. Rotor axle may be in addition reinforced with metallic rod having no contact with solution. Such pump has minimal quantity of slits and threaded joints that decreases probability of mass crystallization.
EFFECT: stable growing of crystals from solution due to eliminating sources of parasitic crystals occurring.
