A worldwide market reference
The range of Cryomec DELTA N pumps is used for high pressure packaging applications (supply to surge/buffer tanks or fillingof cylinders). Its design is adapted to permanent cooling thanks to its trapezoid shape enabling automatic degassing. The cylinder is vacuum-insulated and the heating located behind the cold section prevents the cryogenic liquid from moving towards the crank drive.Cryomec DELTA N pumps cover a wide range of performance with models fitted with several cold sections (duplex and triplex version).

Several technical innovations are available on the Cryomec DELTA N pump. Indeed, the NPSHr may be reduced to 0 bar thanks to the installation of the Supercharger in the cold section.This allows the Cryomec DELTA N to pump the entire capacityof the feeding tank and therefore, to limit the frequency of refilling.The Cryomec DELTA N pump is oriented towards maximum operating safety through its design but also thanks to its instrumentation which enables it to ensure optimum operation in all conditions.
The cold section and the crank drive integrate several technicalinnovations such as (see illustration below):1 - Spherical coupling reducing radial loads and improving
piston alignment2 - Automatic greasing system3 - Seal leakage channelled and detected by a PT100 probe4 - Simplified coupling for easy removal (2 split rings)5 - Connection for nitrogen purging6 - Large-area filter integrated in the cold end
