Oil & Gas
You can rely on 60 years of experience in the construction of pumps, packages, skids, and systems for onshore and offshore oil and gas production. Take a look at the information now!
The transfer of liquefied petroleum gas and liquefied natural gas (LNG) takes place under extreme temperatures, in the case of LNG at −164 to −161 °C. The NIKKISO cryogenic pump is a reliable solution for these applications.
A special cryogenic submersible motor eliminates the danger of leaks and simplifies pump mounting. The bearings have a long service life by a minimal bearing load design. The pumps are available in different models such as those installed in storage tanks, out of which they can be taken when installing in a condensate tank or for fixed installation in tankers.
Moreover, we offer tests in our pump test facility with LNG at -162 °C.
The NIKKISO cryogenic pumps are centrifugal submerged wetted motor pumps with a special cryogenic submersible motor.
Pump components are selected so that all combinations of discharge and pressure are observed. Optimum pump capacities are accomplished by selecting high-efficiency impellers for flow rates and selecting the number of stages to meet pressure requirements.
The constructive design has been tested and approved by Lloyd’s Register of Shipping, BV, DNV, ABS and other classification societies.
NIKKISO is represented globally and maintains various authorized service centers in Europe, USA and Japan.
NIKKISO is certified in accordance with ISO 9001 (quality management standard) and ISO 14001 (environmental management standard).
The NIKKISO cryogenic pump is available in various performance variants. The motor can also be adjusted individually to the respective application.
