Purpose : Pumps of type 5GR-8, 5GRT-8 (5GK-8), 8GRT-8 (8GK-8) and units on their base are designed to pump high abbrous hydroxyes (sand, gravel, ore flotation products, etc.) with the recommended Density up to 1600 kg/m 3, a hydrogen indicator of the pH from 6 to 12, the maximum size of solid particles of 12mm, a volumetric concentration of solid inclusions up to 40% (hardness of inclusions up to 11000 MPa), a temperature of +5 to +60 ° C. Units are designed for operation in heated rooms, or in non -heated rooms and under a canopy at a temperature of the surrounding air from - 20 ° to + 40 ° C.
Poles like GR, GRT, GRK - centrifugal horizontal single -stage console with an axial supply of hydroshesis to the working wheel.
The material of the parts of the flow of the GR, GRT : the working wheel, the discharge, the disk are made of wear-resistant alloy ICh28N2. In the pumps of the GRK, the wear -resistant lining of the housing (corcuscation) is used.
The nature of the shaft of soil pumps type GR, GRT, GRK: soft oil seal with flushing water.
