Ultra-High Pressure Cleaning Machine

BOSI's Black Warrior Cool Series Ultra-High Pressure Cleaning Machines are designed for high-intensity industrial and commercial cleaning. They are available in three models: 4.0KW (20MPa), 5.5KW (24MPa), and 7.5KW (32MPa), all powered by 380V three-phase, with a flow rate of 16L/min.

The entire series features a thickened all-copper pump head and an all-copper induction motor, ensuring durability and corrosion resistance. Features include motor overheat protection, circuit safety protection, self-priming capability, and automatic shut-off when the nozzle is turned off. Equipped with a visual pressure gauge (5.5KW and 7.5KW models) and a reinforced cage frame for stability and reliability.

Accessories include a 2.3-meter inlet hose, an all-copper water gun/long gun, an enlarged filter cup, and an 8-9 meter steel wire hose. High-power models also include multi-angle nozzles (0°, 15°, 25°, 40°). Suitable for ultra-high pressure cleaning operations such as industrial equipment surface cleaning, oil removal, concrete roughening, ship rust removal, and municipal pipeline dredging.

Product Parameters

Product Advantages

Thickened all-copper pump head: The pump body is made of high-strength copper alloy, which is resistant to high pressure, corrosion, and heat dissipation, resulting in a longer lifespan than aluminum alloy pump heads.

All-copper induction motor: With pure copper windings, the induction motor has a simple and reliable structure, runs smoothly at low speeds (1450r/min), has low noise, high torque, and is suitable for continuous heavy-duty operations.

Ultra-high pressure output: up to 32MPa (approximately 320bar), easily removes industrial grease, concrete residue, marine organisms from ship hulls, and old paint layers.

Automatic stop when nozzle is off: The motor automatically stops when the trigger is released, preventing the pump body from overheating, saving energy and extending the overall lifespan of the machine.

Visual pressure gauge (5.5/7.5KW): Real time monitoring of working pressure for easy adjustment and fault diagnosis.

Reinforced cage frame: All-steel welded protective frame protects the pump body and motor from collisions and facilitates forklift handling.

Multi angle nozzle (5.5/7.5KW): 0 ° for strong point shooting, 15 °/25 ° for large-area cleaning, 40 ° for gentle rinsing.

Self-priming dual-purpose: Can be connected to tap water or self-primed (such as water tanks or rivers), suitable for field operations.

Product Comparison

Actual Use Cases

Shipyards need to clean barnacles, rust, and old paint adhering to the hull. Sandblasting is inefficient and highly polluting. Instead, a 7.5kW high-pressure washer (32MPa) from Perth, equipped with a 0° nozzle, uses water pressure to directly peel away hard dirt, cleaning 50 square meters per hour without damaging the base material.

Meanwhile, a 5.5kW model with a 40° fan-shaped nozzle is used to wash oil stains on equipment surfaces, increasing efficiency by three times. The equipment has been running continuously for 8 hours a day for 6 months without any problems.
