Liquefied gas pumps are required for unloading, fuel transfer, filling and fueling processes. There are high requirements: low NPSH values, low level of pulsations transport, mixture transport, high pressure differences, low noise emissions and ATEX conformity. The user, besides the reliable transport of liquid-gas mixtures, also expects the control of outgassing and variations of the steam pressure and more and more popular higher pump efficiencies. The high pump efficiencies lead to low energy consumption, smaller drive assembly and to relatively compact pumps units.
