Karcher HD 8/23 G Classic 3335 PSI Petrol Pressure Cleaner

The Karcher HD 8/23 G Classic Cold Water Pressure Cleaner is a powerful petrol-driven professional pressure cleaner designed for demanding commercial, construction and industrial cleaning applications where access to electricity is limited or unavailable.

Delivering an impressive 3,335 PSI (230 Bar) operating pressure, up to 4,060 PSI (280 Bar) maximum pressure with a turbo nozzle, and a strong 13.3 litres per minute water flow, the HD 8/23 G Classic provides the pressure and rinsing performance required to tackle heavy dirt, mud, grime and contamination across machinery, vehicles, equipment and hard surfaces.

Powered by a robust Karcher G300FA 9.1 HP petrol engine and equipped with a heavy-duty crankshaft pump with ceramic pistons, this machine is built for professional operators who need reliable, portable cleaning performance in tough outdoor working environments.

3335 PSI Heavy-Duty Cleaning Performance

With 3,335 PSI operating pressure and 13.3 L/min water flow, the Karcher HD 8/23 G Classic provides an excellent balance between high pressure and strong rinsing performance.

Pressure is important for breaking down stubborn dirt and contamination, while higher water flow provides the volume required to quickly flush loosened mud, grime and debris away from the cleaning surface.

The combination of 230 Bar pressure and 13.3 L/min flow makes this machine particularly effective for cleaning earthmoving machinery, construction equipment, agricultural machinery, vehicles and heavily contaminated hard surfaces.

When paired with a suitable turbo nozzle, maximum cleaning pressure can reach up to 4,060 PSI (280 Bar) for particularly stubborn cleaning applications.

Powerful 9.1 HP Petrol Engine

The HD 8/23 G Classic is powered by a Karcher G300FA 9.1 HP petrol engine, providing professional cleaning performance without relying on an external electrical supply.

This makes the machine particularly valuable on construction sites, farms, infrastructure projects, parks, remote facilities and mobile worksites where 240 V or three-phase electricity may not be conveniently available.

Petrol power also allows operators to move between different cleaning locations without being restricted by electrical leads, providing greater flexibility for mobile contractors, tradespeople and maintenance teams.

Heavy-Duty Crankshaft Pump

At the heart of the HD 8/23 G Classic is a robust crankshaft high-pressure pump with ceramic pistons.

This pump configuration is designed to withstand demanding professional operating conditions while delivering consistent pressure and water flow.

Ceramic pistons provide excellent wear resistance, contributing to long component life and dependable performance for businesses requiring a pressure cleaner for regular heavy-duty use.

For professional operators, the combination of a powerful petrol engine and crankshaft pump makes the HD 8/23 G Classic a strong choice where reliability and cleaning performance are essential.

High Flow for Machinery and Equipment Cleaning

The 13.3 L/min water flow rate is an important advantage of the HD 8/23 G Classic, particularly when cleaning equipment covered in mud, soil and heavy debris.

While high pressure helps dislodge stubborn contamination, strong water flow helps carry the loosened material away from the surface.

This makes the machine particularly well suited to excavators, loaders, agricultural machinery, construction equipment, trucks, trailers and other commercial equipment where rinsing speed can have a significant impact on overall cleaning time.

Built for Tough Worksites

The HD 8/23 G Classic has been designed for demanding outdoor environments.

A strong tubular steel frame helps protect the engine, pump and major components from the knocks and impacts associated with transport and worksite use.

Puncture-proof wheels provide dependable mobility across uneven surfaces without the inconvenience of flat tyres, while the ergonomic push handle makes the machine easier to manoeuvre around worksites.

Despite its heavy-duty performance, the machine remains relatively compact at 878 x 538 x 702 mm and weighs approximately 44.9 kg, making it practical for mobile professional operators.

Pump Protection and Safety Features

The HD 8/23 G Classic incorporates several features designed to help protect the machine during demanding professional operation.

A large water filter helps prevent contaminants in the incoming water supply from reaching the high-pressure pump, while the integrated thermo valve and safety valve provide additional protection for key components.

These protective features are particularly valuable when a pressure cleaner is regularly used in dusty, muddy or demanding outdoor environments.

Designed for Easy Transport and Storage

Mobility is a key consideration for a petrol pressure cleaner, and the HD 8/23 G Classic has been designed accordingly.

The compact frame, ergonomic push handle and puncture-proof wheels make it easy to move around construction sites, farms, workshops and other commercial environments.

Integrated accessory storage also provides convenient locations for the hose, trigger gun and spray lance, keeping equipment organised and secure during transport between jobs.
