Sand pumps of the type of PA and electric pump units based on them are designed to pump highly abrasive hydrosons (sand, gravel, ore flotation products, etc.) with pH 6 ... 12, density up to 2200 kg/m3, temperature from 278 to 343 K (from 5 up to 70 ° C), voluminous concentration of solid inclusions up to 40%, the maximum size of solid particles 6 mm.
A distinctive feature of sand pumps such as PA - axial supply of the pumped environment.
In the unit of the electric pump, the transmission of the torque from the electric motor to the sand pump is carried out through the sleeve-jacket coupling or cuneiform transmission.
The scope of sand pumps of the type of PA - technological processes of enrichment of non -ferrous and ferrous metal ores.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Unit PA100-170/40", where
PA - type of sand pump;
100 - inner diameter of the pressure pipe in mm;
170 - nominal feed in m3/h;
40 - nominal pressure in m.
Technical characteristics of sand pumps of electricity units their basis.
