The very best in high pressure water jetting equipment
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, we design and build the machines, supply spares and accessories, and offer lifetime service support for your equipment.
The list of uses for high pressure water continues to grow, which is why design and innovation is so important to us. With a range of standard pumps and equipment, along with the ability to produce bespoke systems to suit specific applications, we supply all of your industrial waterjetting equipment requirements.
Our diesel-powered units feature the latest technology with the introduction of the Stage V/Tier 5, 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 high pressure water jetting?
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 to contain all washings and contaminants.

Benefits of Calder Water Jetting Equipment
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 equipment.
At the heart of our units is the Hammelmann reciprocating plunger pump. This pump range is respected throughout many industries for its quality and reliability.
Safe
Our pump 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 products.Cost Effective
Suitable for nearly all applications, the unique 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.
