A 2-stage LNG submerged centrifugal pump for liquid transfer, LNG stations and micro-bulk delivery.
The main advantage of this new pump is that it can be easily installed in all existing piping systems for semi-trailer or stationary use, without modification of the installation.
Its robust design prevents high vibrations giving an extended bearing lifetime.
It is hermetically encapsulated thus no shaft seal is needed.
Its motor bearings are lubricated by the process fluid itself, resulting in a “zero-maintenance” design. In addition, the cooling of the electrical motor is done by the pumped liquid which increases considerably its lifetime.
You can start and stop the pump immediately without cooling it down.
The balanced and machined inducer allows the lowest possible NPSH requirement, all along the performance curve.
It has a highly efficient closed impeller made by “lost wax” casting.
The casing has an optimal shape with a machined axial diffuser with all rotating parts balanced individually.
Its noise level is very low thanks to the submerged design.
