Karcher HD 8/18-4 St 240Bar Stationary Cold Water Pressure Washer 1.524-962.0

The Kärcher HD 8/18-4 ST is a powerful stationary cold water pressure washer designed for permanent installation in industrial, agricultural, transport, and commercial cleaning environments. Engineered for continuous operation, this robust cleaning system combines professional performance with exceptional durability, making it ideal for fixed wash bays, production facilities, workshops, livestock units, and centralised cleaning systems where reliable high-pressure cleaning is required every day.

Powerful Stationary Cleaning Performance

Delivering up to 180 bar operating pressure and a water flow rate of up to 800 l/h, the HD 8/18-4 ST provides the cleaning power needed to tackle mud, grease, oil, and stubborn dirt on vehicles, machinery, equipment, and work areas. Its stationary design ensures immediate availability without the need for transportation or setup before use.

Durable Crankshaft Pump & Water-Cooled Motor

At the heart of the machine is Kärcher’s proven crankshaft pump with ceramic pistons and brass cylinder head, paired with a durable 4-pole low-speed water-cooled electric motor. This professional-grade combination delivers excellent reliability, reduced wear, and long service life under intensive daily operation.

Designed for Continuous Operation

The HD 8/18-4 ST is specifically engineered for fixed installations requiring dependable performance throughout the working day. An integrated water storage tank with float valve protects the pump against water supply fluctuations, while dry-running protection helps prevent damage during operation.

Advanced Safety & Monitoring Systems

Integrated electronic monitoring systems continuously protect the machine from operational faults, including:

• Water shortage protection
• Dry-running protection
• Phase failure monitoring
• Overvoltage protection
• Undervoltage protection
• Leak detection systems

These features help maximise machine lifespan while minimising downtime.

Robust Industrial Construction

The machine features a heavy-duty powder-coated steel frame and housing, providing excellent protection against harsh operating conditions. Its durable construction makes it suitable for demanding industrial, agricultural, and commercial cleaning environments.

Easy Operation & Maintenance

A large rotary control switch ensures straightforward operation, while clear status indicators provide instant machine feedback. The service-friendly design allows quick access to key components, simplifying routine maintenance and reducing service times.

Flexible Installation Options

The HD 8/18-4 ST can be integrated into larger cleaning systems and upgraded with optional accessories including:

• Remote controls
• Pressure gauges
• Operating hour counters
• Automatic pressure relief systems
• Additional detergent dosing equipment

This flexibility allows the machine to be tailored to specific site requirements.
