Uhde High Pressure Technologies GmbH has developed the latest generation of high-pressure filters for water jet cutters

For the successful and faultless operation of a water jet cutter it is decisive to treat the raw water (tap water) such that it meets maximum requirements concerning perfect water. The essential link between high-pressure pump and cutting valve is the high-pressure filter.

That is the point where Uhde High Pressure Technologies GmbH‘s latest development sets new standards with respect to water quality, the maximum durability of all high-pressure components used (e.g. water nozzles, valves, pivots etc.), service lives – all this with maximum flexibility as to mounting, dismounting and installation position as well as simplified handling by customers and maintenance.

We offer the new HP filter with two pressure levels: for cutters of up to 4,000 bar and – at this point we are one of only three suppliers worldwide – up to 6,000 bar (fig. 1). Nevertheless, Uhde guarantees compatibility to all manufacturers and designs of water jet cutting plants and water jet cutting systems in the market!

The centrepiece of our new HP filter is the filter cartridge made of a metal fabric composite. Your advantage compared to the usual cartridges made of ceramics or sintered metals is the large filter surface (3,400 mm²) permitting high flow rates without almost any pressure losses and blockage. In addition, maintenance and cleaning are without problem for the customer (fig. 2).

It is best Uhde tradition that the autofrettage process meets maximum requirements as to lifetime and quality!

All facts and advantages of the new high-pressure filter at a glance:

• Maximum purity of the cutting water

• Longer lifetimes of the HP components thanks to less wear

• Easy mounting and dismounting

• Flexible installation position

• Easy cleaning and maintenance by the customer

• Two designs: 4,000 bar and 6,000 bar

• Compatibility to all manufacturers, designs and years of construction

• Filter cartridges made of metal fabric composite (large surface, high flow rate, low pressure losses)

• Uhde autofrettage extends lifetime
