PB pumps

PB pumps

Sand pumps of the PB type and electrical units based on them are designed to pump highly abrasive hydrosons (sand, gravel, ore flotation products, etc.) with pH 6 ... 12, density up to 1300 kg/m3, temperature from 278 to 343 K (from 5 up to 70 ° C), a volumetric concentration of solid inclusions up to 30%, the maximum size of solid particles 6 mm.

A distinctive feature of sand pumps of the PB type is the side of the pumped environment.

In the unit of the electric pump, the transmission of the torque from the electric motor to the sand pump is carried out through the sleeve-jacket coupling.

The scope of sand pumps of the PB type - technological processes of enrichment of non -ferrous and ferrous metal ores.

The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:

"Unit PB 160/40", where

PB - type of sand pump;

160 - nominal feed in m3/h;

40 - nominal pressure in m.
