Land pumps of type 1GRT 400/40 and electric pump units based on them are designed to pump highly abrasive hydrosons with pH 6 ... 12, density up to 2200 kg/m3, temperature from 278 to 343 K (from 5 to 70 ° C), voluminous concentration solid inclusions up to 40%, 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 1grt 400/40 enrichment factories, metallurgical enterprises.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Unit 1grt 400/40 - 1.6", where
1 - serial number of modernization;
GRT - type of soil pump;
400 - nominal feed in m3/h;
40 - nominal pressure in m;
1.6 - the maximum density of a hydros mixture pumped by the pump unit, reduced by 1000 times, kg/m3.
