WET STATOR PUMP

Special motopump design for no conductive liquid and cryogenic applications.

Cryogenic liquids are gases in the liquid state at very low temperatures. Their boiling points are generally below -130°C (-202°F).

Handling cryogenic liquids, which are used at temperatures below -150°C due to their extremely low boiling points, requires specialized technical know-how to ensure risk-free storage and transfer. The pumps are specifically engineered to manage liquids at these extreme temperatures, ensuring efficient and safe operation without the danger of internal vaporization.

OPTIMEX’s cryogenic pump design is inherently safe, featuring a submerged motor (wet stator) within the cryogenic liquid, thus eliminating any internal ignition risks. The absence of dynamical seals and mechanical packings guarantees no potential leaks. These pumps are versatile, catering to various applications such as liquefied natural gas, liquefied petroleum gases, ethylene, propylene, and more.

The submersible pump configuration allows for installation inside a cryogenic fluid storage tank, removing the need for bottom tank connections and significantly reducing the risk of major external leaks.

Additionally, these pumps can be fitted with an inducer at the tank’s lowest point, enhancing the NPSH required for the pumps and enabling operators to maintain extremely low liquid levels in the tank.

Due to the very low viscosity of cryogenic fluids, pump designs must be adjusted to ensure reliable operation. OPTIMEX pumps integrate these considerations into their design, guaranteeing efficient transfer under any viscosity conditions.

The power cables and slinging system for installation and maintenance are also cryogenic temperature compatible, ensuring seamless operations
