Karcher HD 9/25 G Classic 3625 PSI Petrol Pressure Cleaner

The Karcher HD 9/25 G Classic Cold Water Pressure Cleaner is a powerful petrol-driven pressure cleaner designed for demanding commercial and industrial cleaning applications where strong pressure, high water flow and complete independence from an electrical supply are essential.

Delivering an impressive 3,625 PSI (250 Bar) operating pressure, up to 4,350 PSI (300 Bar) maximum pressure with a turbo nozzle, and a high 15 litres per minute water flow, the HD 9/25 G Classic provides serious cleaning performance for machinery, vehicles, equipment and heavily contaminated hard surfaces.

Powered by a robust Karcher G390FA 11.4 HP petrol engine and equipped with a heavy-duty crankshaft pump with ceramic pistons, this machine is an excellent choice for professional operators requiring powerful and portable cleaning performance in demanding outdoor environments.

3625 PSI High Pressure Cleaning Performance

With 3,625 PSI operating pressure and 15 L/min water flow, the Karcher HD 9/25 G Classic delivers an excellent combination of pressure and water volume for demanding cleaning applications.

High pressure helps break through stubborn mud, dirt, grime and built-up contamination, while the strong 15 L/min water flow provides the volume required to quickly rinse loosened material away.

This combination makes the HD 9/25 G Classic particularly effective for heavy machinery, earthmoving equipment, agricultural equipment, commercial vehicles, construction equipment and hard surface cleaning.

When paired with a suitable turbo nozzle, maximum pressure can reach up to 4,350 PSI (300 Bar) for particularly stubborn cleaning tasks.

Powerful 11.4 HP Petrol Engine

Power comes from a dependable Karcher G390FA 11.4 HP petrol engine with manual pull start.

The petrol-driven design allows the machine to operate independently of an electrical supply, making it ideal for worksites, farms, construction projects and remote locations where access to electricity may be unavailable or impractical.

For mobile contractors and professional operators, this provides the flexibility to take powerful cleaning performance directly to the equipment or area that needs to be cleaned.

The EU Stage V compliant engine is designed to provide reliable performance while meeting modern emissions requirements.

High Flow 15 L/min Performance

One of the major advantages of the Karcher HD 9/25 G Classic is its 15 L/min water flow rate.

For machinery and equipment cleaning, pressure alone is only part of the equation. High pressure breaks stubborn contamination away from the surface, while strong water flow provides the rinsing volume needed to remove mud, soil, grime and debris efficiently.

The combination of 3,625 PSI and 15 L/min makes this machine particularly well suited to larger equipment and demanding commercial cleaning applications where reducing overall cleaning time is important.

Heavy-Duty Crankshaft Pump

At the heart of the HD 9/25 G Classic is a professional crankshaft high-pressure pump with ceramic pistons.

The crankshaft pump design provides reliable and consistent performance under demanding operating conditions, while ceramic pistons offer excellent resistance to wear.

This durable pump configuration is particularly well suited to professional users who need dependable cleaning equipment capable of handling regular commercial applications.

Built for Machinery and Equipment Cleaning

The HD 9/25 G Classic is particularly well suited to businesses cleaning machinery, vehicles and equipment.

Its combination of high pressure and strong water flow provides the cleaning performance required to remove heavy dirt and contamination from excavators, loaders, tractors, agricultural implements, trucks, trailers, construction machinery and commercial equipment.

For operators working across multiple locations, petrol power also means the machine can be taken directly to the equipment rather than relying on access to a suitable electrical connection.

Designed for Tough Working Environments

The HD 9/25 G Classic features a robust tubular steel frame designed to protect the engine, pump and major components from the knocks and impacts associated with worksite use and transport.

Puncture-proof wheels provide reliable mobility across uneven surfaces without the inconvenience of flat tyres.

Despite its strong cleaning performance, the machine maintains compact dimensions of 878 x 538 x 702 mm, making it practical to transport between jobs and store when not in use.

Pump Protection and Safety Features

The HD 9/25 G Classic incorporates several features designed to help protect major components during professional operation.

An integrated water filter helps prevent contaminants in the incoming water supply from reaching the high-pressure pump.

A thermo valve and safety valve provide additional protection during operation, while the tubular steel frame helps shield the engine and pump from external impacts.

These features contribute to dependable operation and help protect the machine when used in demanding commercial environments.

Easy Transport and Onboard Storage

For professional operators moving between worksites, transport and storage are important considerations.

The HD 9/25 G Classic features a compact, slimline design with puncture-proof wheels and ergonomic handling for easier movement around worksites.

Integrated hooks and accessory storage provide convenient locations for the high-pressure hose, trigger gun and spray lance, keeping the equipment organised during transport and storage.
