Diesel pressure washing machine

A diesel pressure washer is a heavy-duty cleaning machine powered by a diesel engine. Unlike electric or petrol washers, diesel pressure washers are designed for industrial and commercial cleaning tasks, where high pressure and long operating hours a

Specifications

• <p> Pressure (Operating / Max)</p><p> ~200 bar to 500 bar (≈ 2,900 psi – 7,200 psi) for very heavy‑duty industrial models.&nbsp;&nbsp;For more standard heavy-duty diesel washers: ~248 bar / 3,600 psi. &nbsp;</p><p> Higher pressure means more cleaning power, especially for stubborn dirt, heavy machinery or concrete.</p><p> Flow Rate (Water)</p><p> ~13 – 23 L/min for ultra-high‑pressure models.&nbsp;&nbsp;More moderate industrial units: ~15‑21 L/min.&nbsp;&nbsp;Some “commercial / construction” washers: ~17 L/min. &nbsp;</p><p> Flow rate determines how much water is delivered, which affects how fast and effectively you can clean.</p><p> Engine Power</p><p> Diesel engine ranging from ~8‑35 HP depending on size and design. Eg. Morclean’s UHP series uses a 26 HP engine.&nbsp;&nbsp;Smaller units might use 6‑10 HP diesel engines. &nbsp;</p><p> More engine power supports high pressure and sustained flow during operation.</p><p> Pump Type</p><p> Triplex plunger pumps (very common) or crank (axial) pumps. Eg. Osaka’s DPW‑250D model uses a crank pump.&nbsp;&nbsp;Brass or forged heads to withstand high pressure. &nbsp;</p><p> The pump type affects durability, maintenance interval, and ability to sustain pressure.</p><p> Start System</p><p> Many models support electric + recoil (manual) start.&nbsp;&nbsp;Some lighter or more mobile units may only have manual start.</p><p> Electric start is convenient; recoil (pull start) is simple and reliable.</p><p> Fuel Tank / Consumption</p><p> Varies. Example: a 9 HP model has a 5.5 L fuel tank and consumes ~2.15‑2.55 L/hour.&nbsp;&nbsp;Larger, hotter models: fuel consumption can be quite high.</p><p> Helps determine how long the machine can run before refuelling, which is very important for remote or long jobs.</p><p> Water Inlet / Suction</p><p> Many diesel washers can suck water from a tank or barrel (self-priming), using a suction hose + filter. Eg. Yanmar model has a 3 m suction hose + inlet filter. &nbsp;</p><p> This feature is very useful where pressurized water supply is not available.</p><p> Hose</p><p> High-pressure hose (e.g., 8 mm / 5/16″) x ~10 m is common.&nbsp;&nbsp;Nozzle set typically includes 0°, 15°, 25°, 40°, and soap nozzles. &nbsp;</p><p> Enough hose length and different nozzles let you adapt to different cleaning tasks.</p><p> Frame &amp; Mobility</p><p> Sturdy steel or tubular frame, often with pneumatic wheels. Eg. 10″ pneumatic wheels. &nbsp;</p><p> Makes machine transportable across rough job sites.</p><p> Safety / Protection Features</p><p> - Thermal relief valve to protect pump from overheating.&nbsp;&nbsp;- Low-oil engine shutoff. Eg. in Osaka’s DPW‑250D.&nbsp;&nbsp;- Engine protection, possibly battery shutoff, etc.</p><p> These help extend machine life and protect operator &amp; equipment.</p><p> Weight / Dimensions</p><p> Typical large industrial machine may weigh 150‑200+ kg (depending on model). (Varies a lot)</p><p> Strong, durable machines tend to be heavy — important for stability and longevity.</p><p> Optional Features</p><p> - Chemical injector (for detergent) - Gauge for monitoring pressure - Hour meter - Thermal protection / bypass unloader - Suction filt</p><p> </p><p> </p>
