Electric pump units of the PBH are made on the basis of PB pumps by using 12x18N9T stainless steel for the manufacture of parts of the prototype part (working wheel, disk, discharge).
The Cetrobious Electric Superior Unit is designed to pump neutral and chemically active fluids with a temperature of -40 to +90 ° C, with a density of not more than 1850 kg/m3 without inclusions or having solid inclusions in size no more than 0.2 mm, the volumetric concentration of which does not exceed 0.1 %. 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.
Electroly pumped units are used in chemical, mining, metallurgical, construction and other industries.
The nature of the shaft of the sand pump shaft of the PBH type: soft oil seal or end seal.
Material of the details of the proto-stringing part : the working wheel-12x18N9T; disk - 12x18n9t; Discharge - 12x18n9t; Subway - 12x18n9t.
PBC centrifugal sand pumps comply with the requirements provided for by TU3631-001-53836603-2007
Conditional designation of pumping units based on PBH type
The designation of the size of the electric pump unit includes (PBX 160/20-SP):
-
Letters:
- PBH-sandy sand, chemical,
- joint venture-ombus flushing seal of the shaft
- T-the end seal of the shaft.
-
numbers: 160-feed in m 3/h,
- 20-the pressure in m.
