APPLICATIONS
CJG pumps are in
accordance with ISO2858 (DIN24256) and ISO5199 and meet requirements for
handling of organic and inorganic media in chemical, cellulose, paper,
petrochemical and siderurgical industries, food manufacturing, etc. The
ATEX version of the CJG pumps applies when the atmosphere of the
installation area runs explosion risks. Both the CJG pump, and their
ATEX and VCJG versions use the same casings and impellers.
CONSTRUCTION
Centrifugal,
single-stage, horizontal, single-flow pump, volute casing, suction and
discharge flanges according to DIN 2501 PN 16. Closed impeller with rear
blades to compensate axial thrust. Shaft largely dimensioned, and free
from contact with the handled liquid, through sleeve and joints. Bearing
bracked with two oil-lubricated bearings (ISO 3448-VG46).
Shaft
sealing by means of soft packing or mechanical seal, this one may be of
any type or trade, provided in accordance to DIN 24960 and the service
conditions.
VCJG pumps are the vertical arrangement of CJG pumps
working immersed in water connected to a surface motor by means of a
line shaft. The pump will have vertical suction and lateral discharge.
