Cat Pumps gets tough on pressure cleaning

01 June 2014

Cat Pumps has announced the development of a new version of its field-proven 5CP positive displacement triplex plunger pump series.

 The new 5CP4120 series meets increasing demands for higher pressures in the heavy-duty high-end pressure washer market.


“Cat Pumps 5CP series plunger pumps set the industry standard for long lasting pressure washer pumps,” comments Brian Hubbard, General Manager of Cat Pumps UK. “Building on that success, we have extended the pressure range from 3,500 to 4,000 psi (245 to 275 bar). Our new 5CP4120 is a highly robust pump which does not compromise either on performance or build quality.”


The compact model 5CP4120 is rated 17 litres/min at 1,750 rpm and can be used in both belt and direct drive applications. To satisfy the demanding requirements of the applications for which this pump has been designed, and to provide a long, low maintenance working  life, the valves and seats are made from 316 Stainless Steel and have been hardened and polished for ultimate performance.


High and low pressure seals are fully lubricated and cooled by the pumped liquid. Combined with Cat Pumps special concentric, high density polished ceramic plungers, this feature greatly increases pump life. When the time eventually comes for seal replacement, this is quick since the 5CP range features ‘press in style’ seal cases.


Both side and rear oil gauge sight-glasses are incorporated into the design of the crankcase to make it easier to check the oil level wherever the pump is mounted. Maintenance is further simplified through the use of “stacked valves” necessitating only three plugs to access the pump valves for inspection and servicing.


For diesel and petrol engine applications, this pump can also be supplied complete with Cat Pumps robust speed-reduction helical gearbox, to fit directly to the chosen engine with a 1” parallel shaft and SAE mounting face.


The 5CP4120 is available in stock for same-day despatch from Cat Pump’s UK headquarters in Fleet, Hampshire, along with installation accessories such as Unloader Valves, and manufacturer’s genuine service spare parts.
