Grau 400/20 soil pumps and electric pump units based on them are designed to pump highly abrasive hydroxyes with pH 6 ... 12, density up to 1600 kg/m3, temperature from 278 to 343 K (from 5 to 70 ° C), voluminous concentration solid inclusions up to 30%, the average size of solid particles 6 mm, maximum size of solid particles 85 mm, microstless up to 11000 MPa.
In the unit of the electric pump, the transmission of the torque from the electric motor to the soil pump is carried out through the sleeve-jacket coupling.
The scope of soil pumps of the GRU enterprise for the extraction of building materials.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Unit Grau 400/20-1.6", where
Grau - type of soil pump;
400 - nominal feed in m3/h;
20 - nominal pressure in m;
1.6 - the maximum density of a hydros mixture pumped by the pump unit, reduced by 1000 times, kg/m3;
