With wide experience in
solving pumping problems, we can provide you with a range of sealless pumps, sealless
canned motor pumps, centrifugal pumps with exceptional operating reliability.
Dynamic 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 features.
The 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
The 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 driving 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 cylinder liner. The 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 environment or internal pumped liquid.
The can represents a static atmospheric seal and separates the rotor compartment
from the stator compartment, such that levels of sealing of < 10 -7cc /sec
are achieved. To ensure integrity of the canning. The versatile drive system has
exceptionally improved the operating limits for pressure, temperature and toxicity
of the flow of the product responding to heightened safety and environment protection
requirements all over the world. Dynamic canned motor pumps are flame poof and
are cmri certified to EEx-d 11b T4(Ex) ds, IS: 2148-2004 AND weather proof protection
: IS:12063-1987, IP-67.
