at Pumps has extended its 35- frame series high pressure triplex positive displacement plunger pumps with the introduction of the Model 3550.

A new version of Cat Pumps 5CP positive displacement triplex plunger pump series, the 5CP4120, meets increasing demands for higher pressures in the heavy-duty high-end pressure washer market.

Cat Pumps has announced enhancements to one of its 345bar high pressure pumps used extensively for pressure testing, heavy-duty pressure washing including graffiti removal and in industrial processes.

An ambitious scientific mission to collect water and sediment samples from Lake Ellsworth, some 3km beneath solid ice in Antarctica, is using positive displacement triplex pump technology to provide high pressure hot water for an innovative borehole drilling system.

Cat Pumps UK has developed and tested a full range of high pressure triplex pumps for use in Explosive Atmospheres. Thanks to their high standard of design and manufacture, standard high pressure triplex pumps require very few modifications to make them suitable for use in hazardous areas. Generally, minimising the risk of sparks caused by a build up of static electricity and strengthening a few parts to protect against accidental damage is all that is necessary.

While many coal seams are no longer worked in this country, these almost forgotten sources of energy are the subject of a revival of interest as entrepreneurs seek to realise the potential of coal-bed methane for power generation. Pumps play a key role in the extraction process

Unless one is an expert in fluid dynamics or pump technology, selecting the most appropriate pump for a specific application is not always straightforward. There are many factors that will influence the pump selection process, such as the pressure required and the nature of the fluid being handled, that will determine the type of pumping principle that is most appropriate.
