Our experienced Aftermarket Services Group can provide all of your service needs, with supervisory services from initial installation, commissioning, maintenance, repairs and training, to assistance with spare parts management and operational procedure review.
Specially developed ZEN™ spiral inducers to provide extremely low pumpdown characteristics.
Pioneer of first high pressure vaporizer feed pumps for FSRU's with more marine and offshore high pressure pumps built than any other competitor by far.
Multiple bearing technology for multistage high pressure pumps to ensure rotor dynamic stability and unsurpassed reliability.
Exclusive horizontal assembly process for large, multistage high pressure pumps, reducing the need for specialized pump maintenance facilities at the job site.
As a result of unique design features that control bearing loads, Nikkiso Cryo pumps have unparalleled reliability in the field. In many cases, mean time between maintenance is over 20,000 hours, with some pumps recording up to an astonishing 43,000 hours.The terminal header used in our pumps' electrical system offers extended leak-free operation. This design was proven in the nuclear industry and has a perfect 25-year record. Our extensive instrumentation system permits us to conduct computer-controlled performance and NPSH tests with live tracking of more than 200 parameters.
This design is provided with the pump and suction vessel which become an integral part of the piping system with external suction and discharge connections. The pump is mounted to the top or headplate of the vessel such that the pump, motor and fluid product are totally contained within the pressure vessel. Shaft seals are eliminated. The pump inlet is below the suction vessel inlet which allows the source tank liquid levels to be lowered to
Removable, or in-tank pumps offer the advantage of overhead removal and installation without taking the tank out of service.The pump operates at the bottom of a purpose-built pump column through which it is installed and removed. The column provides the fluid discharge from the pump to the top of the tank and contains the lifting cables as well as the power cables...
This pump type is mounted directly to supports in the bottom of a storage tank and connected to a discharge pipe which extends to the top of the tank and out to the discharge piping. This simple and low cost design is used in liquefied gas carriers and in any other application where removing the liquid from the tank for maintenance is a normal or required process and can be accomplished without excessive costs to the tank or system...
