The Karcher HD 10/25-4 S Cold Water Pressure Cleaner is a powerful three-phase industrial pressure cleaner engineered for demanding professional cleaning applications. Delivering 3,625 PSI (250 Bar) operating pressure and an impressive 16.6 litres per minute water flow, the HD 10/25-4 S combines high cleaning pressure with strong water volume for fast and effective removal of stubborn dirt and contamination.

Designed for heavy-duty commercial and industrial use, this machine is particularly well suited to transport fleets, construction equipment, earthmoving machinery, manufacturing, agriculture and industrial washdown applications where cleaning performance, reliability and operator comfort are essential.

250 Bar Industrial Cleaning Performance

The combination of 250 Bar operating pressure and 16.6 L/min water flow gives the Karcher HD 10/25-4 S excellent cleaning impact while maintaining the water volume required to quickly flush loosened contamination from the surface.

This balance is particularly important when cleaning large machinery and equipment. High pressure helps break through stubborn dirt, while the strong water flow efficiently removes mud, debris and other contaminants to help reduce overall cleaning time.

For businesses regularly cleaning trucks, machinery, industrial equipment or large hard surfaces, the HD 10/25-4 S provides a substantial step up from smaller commercial pressure cleaners.

Heavy-Duty 4-Pole Low-Speed Motor

Power comes from a robust 9.2 kW, 4-pole low-speed electric motor designed for demanding professional operation.

The low-speed motor configuration helps reduce mechanical wear and provides smooth, reliable operation during extended cleaning periods. An efficient air-water cooling system helps regulate operating temperatures and contributes to long component life under demanding workloads.

Operating from a three-phase, 20 Amp electrical supply, the HD 10/25-4 S is ideally suited to industrial facilities, workshops and commercial sites requiring dependable high-output electric pressure cleaning.

Heavy-Duty Karcher Pump Technology

The HD 10/25-4 S incorporates a durable high-pressure pump featuring stainless steel pistons and a brass cylinder head.

This heavy-duty construction provides excellent wear resistance and dependable pressure delivery under demanding commercial and industrial operating conditions.

Combined with the low-speed motor, the pump system is engineered for businesses requiring reliable professional cleaning performance and long equipment life.

EASY!Force Advanced for Reduced Operator Fatigue

Karcher's EASY!Force Advanced trigger gun uses the recoil force of the high-pressure water jet to significantly reduce the holding force required by the operator.

This can make a substantial difference during extended cleaning jobs, particularly in industrial environments where operators may be pressure cleaning machinery or equipment for long periods.

The machine is also equipped with Servo Control, allowing pressure and water flow to be adjusted directly from the lance to suit different surfaces and levels of contamination.

Professional Karcher Accessories

The Karcher HD 10/25-4 S is supplied with:

• 10 m high-pressure hose
• EASY!Force Advanced trigger gun
• Dirtblaster rotary nozzle
• 1050 mm rotating stainless steel spray lance
• Servo Control for pressure and water flow adjustment

The Dirtblaster provides powerful rotary cleaning action for heavily contaminated surfaces, while the long stainless steel lance provides excellent reach for machinery and equipment cleaning.

Designed for Industrial Mobility

Despite its high cleaning output, the HD 10/25-4 S features a relatively compact upright design engineered for practical movement around industrial sites.

Integrated aluminium frame carriers provide additional structural strength and allow the machine to be handled during transport and crane loading where required.

At approximately 70 kg, the machine provides heavy-duty construction while remaining practical for professional environments where equipment may need to be repositioned between cleaning areas.

Intelligent Monitoring and Equipment Protection

The HD 10/25-4 S incorporates intelligent assistance systems with an LED status display, providing operators with clear machine information and alerts during operation.

These systems make daily operation more intuitive while helping users identify operating conditions that may require attention.
