Sand pumps of the PVPA type and electro-pump units based on them are designed to pump highly abrasive hydrosomes (sandy, sandy, gravel, ore flotation products, etc.) with pH 6 ... 12, density up to 2200 kg/m3, temperature from 278 to 343 K (from 5 to 70 ° C), volumetric concentration of solid inclusions up to 30%, maximum solid size particles 6 mm.
In the power supply aggregate, the torque transmission from the electric motor to the sand pump is carried out through the sleeve-plot-fracture hollow.
sand pumps of the PVPA type are used for hydrotransport of pulps from zumps, columns, water collectors and other containers on Enriching factories when washing floors, as well as for pumping foam pulp: in mining, metallurgical, construction and other industries.
The structural designation scheme of the electricity unit when ordering, correspondence and technical documentation:
