SEALLESS CANNED MOTOR PUMPS
Leak free pumping for Safer
wide experience in solving pumping problems, we can
provide you with a range of Sealless, centrifugal pumps
with exceptional operating reliability.
Canned Motor Pumps
are highly efficient due to reduced life cycle operating
cost, zero fugitive emissions, eliminating environmental
pollution risks and allowing very safe pumping of fluids
without wastage of valuable, hazardous -- even explosive
fluids, due to sealless construction and other unique
wide range of models available allows top quality standardization.
HIgh efficiency is combined with superb handling and
ease of installation is attributed to the experience
of the Dynamic Team and close collaboration with large
number of customers.
uniqueness of its Drive Motor Construction is that,
there is no dynamic shaft seal, no coupling and no ball
bearings. The motor is cooled by the pumped liquid and
the sleeve type bearings are lubricated by the same
liquid. This eliminates the need for external lubrication.
The stator of the dricing motor, which is usually three
phase squirrel cage induction motor, is hermetically
contained in a stator containment that consists of external
frame tube, outboard and inboard end plates and internal
Rotor which is welded on the shaft, is also encapsulated
with a non-magnetic liner. Both stator can and rotor
can are seal welded at both ends, and does not allow
any part of the motor to be exposed to external enviroment
or internal pumped liquid. The can represents a static
atmospheric seal and separates the rotor compartment
from the stator compartment, such that levels of <10
cc/sec are acheived to ensure integrity of the canning.
The versatile drive system has exceptionally improved
the operating limits for pressure, temperature and tosicity
of the flow of the product responding to heightened
safety and environment protection requirements all over
the world. Dynamic canned motor pumps are flame proof
and are CMRI certified to EEx-d
11b T4(Ex) ds,IS: 2148-204 AND weather proof protection
: IS:12063-1987, IP-67.
& Space Requirements
Dynamic Canned Motor Pumps are characterized by extremecompactness
and consequentially low space requirements, because
the pump and motor form integral unit, neither base
late nor special foundations are required, our units
are not at all sensitive to distortion caused by the
piping, this is of special importance if heat transfer
oils are to be pumped at high temperatures. This allows
the pump to ne installed in otherwise inaccessible place
for eg. in ships and nuclear power station -- being
noiseless and vibration free.
to more stringent health and safety regulations canned
motors are beneficial replacement, if properly installed
and operated, canned motor pumps render technical processes
maintenance free and safe and contribute to increases
productivity and reduced maintenance costs.
