Karcher HD 9/50 Ge Petrol Powered Ultra High Pressure Cleaner

The Karcher HD 9/50 Ge Petrol Powered Ultra High Pressure Cleaner is a petrol powered Ultra-High Pressure Cleaner, which operates with a working pressure ranging from 150 to a maximum of 500 bar (15 to 50 MPa). This immense pressure is what allows it to remove difficult substances like paint, rust, and thick dirt. The unit has a high water flow rate of 500 to 900 liters per hour, ensuring a large volume of water is delivered for efficient cleaning.

High-performance crankshaft pump
Reliable and durable Kärcher high-performance crankshaft pump ensures optimal pressure.

Robust Cage Frame
The machine is built with a sturdy cage design that provides all-around protection for its components. This frame also includes a crane hook, allowing for safe and easy lifting with a crane or forklift.

Portability
Despite its size and weight (around 150-195 kg with accessories), it’s designed for transport. It has a “pushcart principle” with large, air-filled tires, making it easy to manoeuvre on rough or difficult surfaces like construction sites.

Convenient Storage
The unit has an integrated lance holder and hose hook, ensuring accessories are always ready and organized. There’s also a protected box for storing tools and other accessories.

User-Friendly Features
Includes an hour meter to track the pump’s operating time for maintenance purposes. An optional dry-run cut-out feature protects the pump and the user from damage in case of water shortage.

Application areas
Cleaning construction machinery, vehicles, and tanks.
Removing tire deposits from airport runways.
Washing and preparing surfaces in industrial facilities.
Cleaning pipelines, reservoirs, and cisterns

Cleaning ships is a major application for high-pressure and ultra-high-pressure cleaning systems, and the Kärcher HD 9/50 is a prime example of a machine built for this kind of work. The immense pressure and high flow rate are essential for tackling the tough cleaning challenges found in the maritime industry.

Biofouling Removal – One of the most common and critical tasks is removing biofouling—the accumulation of marine organisms like algae, barnacles, and mussels on a ship’s hull. This growth increases drag, which in turn leads to higher fuel consumption and costs. Regular cleaning with a powerful pressure washer is a key part of an anti-fouling maintenance program. While this often involves specialized underwater equipment, powerful pressure washers are a common tool for removing biofouling and preparing surfaces in dry docks.

Surface Preparation – Before a ship can be repainted or have a new anti-fouling coating applied, the surface must be completely free of old paint, rust, and dirt. Ultra-high-pressure cleaners can strip away these layers down to the bare metal, providing an ideal surface for new coatings.

Rust and Paint Removal – The corrosive saltwater environment means that rust and flaking paint are constant problems. The high pressure of a machine like the HD 9/50 can effectively blast away these layers, preparing the surface for repairs. The ultra-high pressure is perfect for stripping old paint and coatings from a ship’s hull and other steel surfaces.
