  • EDUR - Model NHE LBE - Liquid Gas Pumps

    Liquid gas pumps are required for unloading, fuelling, fuel transfer and for filling processes. The demands are high: high pressure differences, mixture transport, low NPSH values, low level of pulsations transport, low noise emissi- ons and ATEX conformity. The user does expect a reliable transport also of the liquid-gas mixtures, the control of ...

  • NYB - High Pressure Backward Curved Fans

    New York Blower High-Efficiency High Pressure Backward Curved fans feature a backward-curved wheel designed for clean-air applications, but is still capable of handling light particle-laden or moist airstreams. Air-handling efficiencies of the HP Backward-Curved Fan are higher than common radial fans and, therefore, offer lower noise levels.
