Cat High Pressure Piston Pumps

The CAT pumps range of high pressure triplex piston pumps are heavy duty and robust, they are utilised for many high pressure applications within the industrial and marine markets. These positive displacement piston pumps are capable of handling fluids with a viscosity up to 500cp and can achieve pressures up to 103 bar.


The unique CAT pump design is what makes them capable of achieving such high pressures that are outside the realms of other pump types. Fluid moves though the piston pump in one continuous smooth direction. This design allows the pump to achieve higher suction capabilities and also reduces the risk of cavitation. Chambers within the pump hold a precise amount of fluid, this ensures a constant and precise flow is always provided. Changing the speed of the CAT pumps via a gearbox or VFD allows the pump to achieve varying flow rates while maintaining a constant high pressure.


A Pulsation dampener can be provided with the piston pump to reduce pulsations and improve the already smooth flow. Pressure regulating and pressure relief valves can also be provided to ensure the correct pressure is maintained and as a safety feature to protect the operator.


Common applications for CAT piston pumps include high pressure cleaning, misting, cooling and fogging, energy, oil and gas, marine, construction and quarrying, transport and vehicles, agriculture, food and drink, metalworking and manufacturing, chemical and processing, reverse osmosis and water, environment and waste.


There are a variety of models within the CAT triplex piston pump range that are available in 316 stainless steel and brass. Seals and o-rings are also available in a wide range of materials, including Viton, EPDM, PTFE and NBR; this makes CAT pumps extremely versatile and compatible with a wide range of fluids.

Cat Pumps have developed their own special formula Cat oil for their non-food grade pumps. It is a hydraulic oil containing additives such as anti-wear stabilisers and anti-corrosion technology. These additives provide further lubrication to the crankcase that is not provided by standard oils. We can supply this oil in various container sizes. Using alternative oil may lead to more frequent oil changes being required and premature wear of the crankcase components.
A pulsation dampener reduces pulsations in the pipework downstream from the pump. A pulsation dampener is typically required if the system is sensitive to pulsations and requires a smooth flow, such as hydrostatic testing or reverse osmosis. Pulsation dampeners or accumulators have additional benefits like reducing vibrations in pipework and extending the life of components downstream from the pump, such as regulating valves. By reducing pulsations and vibrations, the risk of water hammer is significantly reduced, and operators experience less fatigue when using hand operated nozzles.
Our recommendation is to have both an unloader/regulator valve and a secondary relief valve. A regulating valve is the primary protection for the pump and operator, this regulates pressure to the required amount for the system. The unloader valve relieves pressure and protects the pump and the operator during nozzle applications. The unloader valve will open and relieve the excess pressure when the nozzle is closed. A further relief valve should be installed as a last line of defence in case the regulator/unloader valve fail to operate. The relief valve is typically set around 200-300 PSI above the unloader/regulator set pressure.
Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the pump casing, piston, o-ring and mechanical seal. It may be that more than one material is suitable for your fluid and selection could be based on the application type. For instance; cast iron, bronze and stainless steel are all suitable for fresh water. If it is a simple washing application, then the most cost-effective material cast iron will be best. However, if it is a sanitary application, then stainless steel or bronze are better choices.
Piston and plunger pumps are very similar is design and are both utilised for applications requiring very high pressures, such as; cleaning, misting and reverse osmosis. The main difference between the two pump types is that plunger pumps are installed with a different high-pressure seal design. This allows plunger pumps to achieve much higher pressures than piston pumps.
