  Pump Vaporiser Unit (PVU) - MAN Energy …

  Low-pressure submerged pumps ARTIKA Series are characterised by the absence of gaskets and seals subjected to wear, ensuring extremely high reliability and extended lifetime. The pump remains constantly submerged in the cryogenic liquid so it results always ready to start, avoiding cooling-down downtimes.

  Effects of cryogenic medium on the weakly compressible …

  2023126 · On the basis of the weakly compressible assumption, large-eddy simulation of a high-speed centrifugal pump is performed at a rotational speed of 9685 r/min and flow rate of approximately quarter load (0.23 Qd). Three cryogenic media, namely, liquid methane (MM), liquid nitrogen (MN), and liquid oxygen (MO), are used. Results show that many of …

  [Basic Knowledge about Cryopumps 1 ] | ULVAC …

  1.What is a cryopump? A cryopump is vacuum pump that traps gases and vapors by condensing them on a cold surface. For efficient evacuation under ultra-high vacuum, the vapor pressure for condensation, or the equilibrium pressure for adsorption must be less than 10 -8 Pa. Figure 1 shows vapor pressures of different gases.
