Selection guide
Which one fits your duty?
A first pointer — send us medium, flow, head, temperature and pressure and our engineers will confirm the selection.
| Your duty | Consider |
|---|---|
| Boiling liquids, very low NPSH, gas content | Bungartz → |
| Heating or cooling acids and other highly corrosive liquids | GAB Neumann graphite → |
| Thermal expansion, vibration and misalignment in piping | Witzenmann HYDRA® → |
| Aeration and pneumatic conveying air, lower power than Roots | Tianrui maglev blowers → |
| Turbine, compressor and large-motor bearings | Waukesha Bearings → |
