Cold water high-pressure cleaner HD 25/15-4 St

three-phaseelectricstationary

Product overview
The Kärcher HD 25/15-4 St is a stationary cold water high-pressure cleaner engineered for intensive continuous operation in demanding industrial environments. It delivers a working pressure of 100–150 bar and a flow rate of 750–2500 l/h, supporting simultaneous use by up to 3 users. The machine features a crankshaft pump with brass cylinder head, stainless steel frame and cover, and a slow-running 4-pole motor with soft start. An integrated display reports operating parameters, fault messages and maintenance reminders. Dual supply tanks include dry-running and descaling protection for reliable operation.

Features and benefits
Robust and reliable for tough applications

• Crankshaft pump with brass cylinder head and ceramic pistons designed for continuous operation.
• Low-speed industrial pump and 4-pole motor with soft-start to reduce wear and extend service life.

Easy and intuitive operation

• LED display shows operating status, faults and pending pump maintenance.
• Practical rotary switch for on/off control.
• Remote control connection and capability to manage up to 6 extraction points.

High-quality equipment

• Integrated elapsed time counter and pressure gauge for clear operating information.
• Stainless steel frame and cover for corrosion resistance, hygiene and durability.
• Two supply tanks with float valve, dry-running protection and temperature monitoring at the inlet.

Ready for use quickly at any time

• Pump activates when the trigger gun is operated, enabling immediate work from any supply point.
• No setup time required; stationarity removes the need to transport mobile units.
• Fast availability increases productivity and operational flexibility.

Simultaneous use by up to 3 users

• Immediate cleaning start at extraction points reduces downtime.
• Parallel operation increases throughput and saves time.
• Centralised cleaning reduces investment and maintenance costs compared with multiple mobile units.

Electronic monitoring for operational safety

• Automatic shut-off in case of leaks or phase failure.
• Overvoltage and undervoltage protection for the motor and electronics.
• Dry-running protection to prevent pump damage.

Designed for continuous industrial use

• Durable materials (stainless steel, brass) and robust construction minimise downtime and maintenance.
• High cleaning capacity and fixed installation reduce setup times on site.
• Cost-effective through long service life and low repair requirements.

Simple maintenance and serviceability

• Easy access to components shortens downtime for routine checks and repairs.
• Quick maintenance procedures increase machine availability.
• Lower operating costs due to simplified servicing.

Flexible and versatile

• Wide range of compatible accessories and multiple extraction points for varied work sites and tasks.
• Adaptable to additional areas with increased cleaning requirements.
• High productivity through simultaneous use by multiple operators at different stations.

Accessories and options

• Automatic pressure relief (option).
• Remote controls for local operation at the point of use (option).
