Canned Pump
Canned motor pumps are preferred
in the chemical and petrochemical industry, but also for simple pumping tasks,
such as circulating pumps in industrial refrigeration equipment.
In general, the following media
are conveyed: aggressive, toxic, explosive, hot, cryogenic, malodorous,
volatile, flammable or carcinogenic substances – in brief, media that represent
an environmental and health hazard.
Advantages of canned motor pumps at a glance:
- Absolute leak tightness to the outside.
Canned motor pumps meet the highest environmental protection standards.
- Double containment shell to the
atmosphere. The motor housing and terminal box are designed as
pressure-containing parts and as a second containment shell.
- Extremely low sound level
- ZART® technology ensures non-contact, wear-free
operation of the rotor unit
- Practically no wear and minimal
maintenance
- High availability and long
service life
- Reduced maintenance and low
life cycle costs
- Higher MTBF values compared to
conventional chemical pumps with mechanical seal
- Easy installation, no alignment of motor and coupling required
·
Canned motors
are employed wherever hot,
aggressive, explosive, toxic or radioactive fluids need to be pumped, which is
why a great deal of focus is placed on hermetically sealed pump sets
without gland
packings or mechanical
seals. Canned motors
are used for circulators reactor circulating pumps
(see Reactor
pump), and process
pumps for
chemical and process engineering applications.

Canned – sump pump, not enough npsh, in our plant for
solvent (500-600 kg/m³)
Impeller under the ground, impeller of the pump is underground
to provide head for pump and suction
Solvent booster pumps are canned and solvent feed pump are
canned type

Lean or rich gluycool can be water content , can be solvent
or water or gas content in gas or h2s or co2
Production crossover
ALL HEAT XCHNAGERSS ARE CONSIDERED AS A PRESSURE VESSEL SO
THEY HAVE A PSV AS PER THE ASME CODE ON BOTH SIDES
ALL VESSELS COZ OF THE ACCUMULATION PRESSURE WILL HAVE PRESSURE
CLASS CHANGE AT THE BOTTOM AND ITS BEST TO HAVE IT AT THE NOZZLE SINCE THE
NOZZLE WILL HAVE A PRESSURE CLASS CHANGE ANYWAYS
