Markets and applications

CAT PUMPS high-pressure pumps have been used in vehicle wash systems for over 50 years – from car wash bays to truck, bus and transit wash installations. The triplex piston pump introduced in 1968 already achieved a markedly longer service life than the pumps available at the time, and the range has followed that design ever since.

Several drive options are available for continuous-duty wash operation: belt drive, direct drive, flexible coupling, clutch drive and complete power units built to customer specification.

In commercial and industrial cleaning, CAT PUMPS high-pressure pumps run in continuous duty – in stationary installations as well as mobile on vehicles and trailers. Drive options include electric motors, combustion engines, hydraulic and pneumatic drives and power take-off shafts.

Typical applications:

• High-pressure cleaning of surfaces
• Sewer and pipe cleaning, hydro excavating
• Condenser tube and hood vent cleaning
• Decontamination and high-pressure firefighting

In reverse osmosis systems the feed water has to be delivered continuously against the back pressure of the membrane. Positive displacement pumps from CAT PUMPS maintain a constant flow rate regardless of system pressure and are designed for continuous duty.

They are used in reverse osmosis as well as in other stages of water treatment – efficient and dependable even under demanding operating conditions.

For misting, fogging and cooling, a complete range of brass and stainless steel pumps is available. The drive is matched to the duty: compact direct-drive units for lower-demand applications, belt drive from an electric motor or engine, and gearbox drive from an engine.

For deionised water, flushed manifolds in 316 stainless steel are available. Systems can be sized for any number of nozzles and controlled by variable frequency drive and PLC, which keeps energy consumption and maintenance low and extends system life.

In the oil and gas industry, high-pressure pumps have to deliver reliably under harsh conditions and over long running times. CAT PUMPS pumps are designed for continuous duty, operate at above 85 per cent efficiency and require little maintenance.

Typical applications:

• Secondary and enhanced oil recovery (EOR)
• Crude oil transfer and LACT units
• Triethylene glycol dehydration
• Seal gland flushing

In food, beverage and pharmaceutical processing, CAT PUMPS high-pressure pumps are valued for their reliability in demanding applications. Typical tasks are high-pressure homogenisation and conveyor belt cleaning, along with numerous related process and cleaning duties.

As positive displacement pumps they deliver a constant flow regardless of system pressure and are designed for industrial continuous duty. This also makes them suitable for high-pressure applications in agriculture and food processing.

Advances in technology and environmental requirements have increased interest in water-based hydraulic systems, in industrial plant as well as in mobile applications as well as in mobile applications. Using water as the pressure medium instead of hydraulic oil reduces the environmental burden and brings further advantages in operation.

CAT PUMPS has been supplying pumps for water-based hydraulics for over 50 years. Engineering work and close contact with users have produced versatile solutions, with a broad range of wet-end materials and drive options to suit the individual application.

Positive displacement pumps deliver a constant volume regardless of system pressure. This makes it possible to build up the test pressure and hold it for the required time – the basic requirement of any pressure test on components, vessels and pipe sections.

Typical tasks:

• Verifying burst pressure and structural integrity
• Finding and locating leaks
• Meeting safety regulations, certifying repair work
• Machine tool coolant supply and water deburring in manufacturing
