The very best in high pressure water jetting equipment

MultiJet mobile jetting unit

From major construction and civil engineering projects, decommissioning and decontamination of nuclear installations, surface preparation of ships’ hulls, to the removal of product contamination in chemical plants, vessels and reactors, our MultiJet ultra high pressure waterjetting machines have led the water jetting industry for over 30 years.

The list of uses for ultra high pressure water jetting pumps and systems continues to grow, which is why design and innovation is such an important part of our waterjet offering. With a range of standard water jetting pumps and units, along with the ability to produce bespoke systems to suit specific applications, we supply all your industrial water jetting requirements.

Our diesel-powered units feature the latest diesel engine technology with the introduction of the Stage IV/Tier 4, ultra-low emissions power unit suitable for all low sulphur fuel markets. Where geographic markets allow, we have more suitable engine choices within our range.

Why Waterjetting?

It is a dust-free technique allowing simultaneous, adjacent activities such as lagging and painting to continue, minimises the waste stream, reduces clean-up time, is not weather dependent, and when used in surface preparation operations is proficient at exposing the original profile without further erosion and guarantees the highest level of cleanliness of all surface preparation methods. Ancillary vacuum equipment can be used in conjunction with our water jetting pump technology to contain all washings and contaminants.

Benefits of Calder Water Jetting Units

Reliable

Reliability and ease of maintenance have been designed into the MultiJet range over thirty years. Design, coupled with improved component selection and monitoring has been fundamental in the reliability of our water jetting equipment.

At the heart of our high and ultra-high pressure water jetters is the Hammelmann reciprocating plunger pump. The Hammelmann pump is respected throughout many industries for its quality and reliability.

Safe

Our waterjetting units are inherently safe through sound design, quality component selection, and good assembly techniques and procedures based on industry best practice.

We conduct City & Guilds-accredited water jet safety training in accordance with the Water Jetting Association guidelines, and we also offer training in the operation and maintenance of all our water jetting units.

Cost Effective

Suitable for nearly all applications, the Hammelmann sealing system gives unrivalled service life and uptime advantages over traditional packing seal technology. Wear is gradual, over many thousands of hours, so scheduled repairs and maintenance are all that is necessary rather than frequent ad hoc packing seal changes required by other pumps. This results in a much-reduced lifetime cost of ownership.

Versatile

We have a water jetting unit to suit:

  • mobile
  • static
  • enclosed
  • semi enclosed
  • noise reduction
  • electric driven
  • diesel driven
  • on-board control
  • remote control
  • variable speed control
  • high pressure
  • ultra high pressure

  • lightweight options

Controls

We offer various control options to suit your requirements – from basic push-button controls to comprehensive HMI touchscreen control, monitoring and datalogging functions.

Performance Options

In addition to a large range of pump models, performance conversion kits are available for all water jetters, allowing the operating pressure to be changed in a short time to maximize equipment utilization.

Water Jetting Applications:

  • cleaning – of food conveyors, fish nets, castings, tanks, reactors, vessels, pipes, tubes, tube bundles, filter press backflushing, sewers
  • removal – of concrete, paint, coatings, rubber, elastomeric, urethane, road markings
  • preparation – of metal surfaces prior to painting, road surfaces
  • and - deburring, descaling, hydrostatic testing, cutting, steel atomization, cooling water

Who Uses High Pressure Water:

As you can see from the water jetting applications above, high pressure water is used across a wide range of industrial sectors – and the list is growing. To see how your company can benefit from high pressure water email sales@calder.co.uk or phone +44 (0) 1905 759090
