GRT 1250/71 type soil pumps and electric pump units based on them are designed to pump highly abrasive hydroxyes with pH 6 ... 12, density up to 1300 kg/m3, temperature from 278 to 343 K (from 5 to 70 ° C), voluminous concentration solid inclusions up to 30%, with the size of solid particles up to 12 mm, micro -hardness 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 GRT 1250/71 Adjustment factories, metallurgical enterprises.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Aggregate of GRT 1250/71 - 1.3", where
GRT - type of soil pump;
1250 - nominal feed in m3/h;
71 - nominal pressure in m;
1.3 - the maximum density of a hydros mixture pumped by the pump unit, reduced by 1000 times, kg/m3.
