Ground pumps of the type GR 160/32 (5GR-8*) and electrical units based on them are designed to pump highly abbrous hydromes with pH 6 ... 12, density up to 2200 kg/m3, with a temperature of 278 to 343 K (from 5 to 70 ° C), volumetric concentration of solid inclusions up to 40%, the average size of solid particles 6 mm, maximum size of solid particles 12 mm, microcharles 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 GR 160/32 (5GR-8*) enrichment factories, metallurgical enterprises.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Unit GR 160/32 - 1.6", where
GR - type of soil pump;
160 - nominal feed in m3/h;
32 - nominal pressure in m;
1.6 - the maximum density of a hydros mixture pumped by the pump unit, reduced by 1000 times, kg/m3.
*in the brackets indicate the designation of the pump operating until 1973
Technical characteristics of the soil pump GR 160/32 (5GR-8*) and an electric pump unit based on it.
