New 4,000-bar direct-drive pump WITH a 4,000 bar operating pressure yet low energy consumption, the newWoma EcoJet 70M 4000/4 is a cost-saving, ultra-high pressure, direct-drive pump for waterjet cutting system operators. Its compact dimensions mean that the unit with its plunger pump is easily installed in new or existing systems. The EcoJet 70M 4000/4’s plunger pump uses very little oil and runs very quietly, with a noise rating of just 80 dBA. The direct drive uses up to 30 per cent less energy. These are significant improvements on the performance of pressure intensifier units. The EcoJet is suitable for abrasive and pure water cutting and can also be retrofitted into waterjet cutting systems for metal, stone and plastics. Waterjet cutting uses a very fine jet with an optimal combination of pressure, water quantity and nozzle. The jet can cut at a very high speed, producing an edge-free cross-section and few shavings. Multilayer material can also be cut without problems and is not crushed in the process. Furthermore, the EcoJet is barely heated with the use of water, so the process is also suitable for use with heat-sensitive materials that would melt or change in shape if they were sawn.
