NEWLAND diesel high pressure washers are designed for professional cleaning jobs where strong water pressure, mobility, and reliable operation are essential. Powered by diesel engines, these machines can work independently of an electrical power supply, making them suitable for construction sites, farms, industrial facilities, equipment yards, fleet maintenance areas, and other remote or off-grid locations.
Our diesel pressure washer range includes the DE200A, DE250A, DE200B, and DE250B, covering rated pressures from 200 to 250 bar (2,900–3,625 PSI) and maximum pressures up to 276 bar (4,000 PSI). Depending on the model, maximum water flow reaches 12.6–15 L/min, providing the cleaning force needed to remove mud, grease, oil deposits, hardened dirt, and other heavy contamination from machinery, vehicles, floors, and working surfaces.
For distributors, equipment dealers, contractors, rental businesses, and industrial buyers, NEWLAND also supports OEM/ODM cooperation, bulk purchasing, customized branding and packaging, export packaging, spare parts support, and technical service.
| Model | Rated Pressure | Max Pressure | Max Flow Rate | Engine | Best For |
|---|---|---|---|---|---|
| DE200A | 200 bar / 2,900 PSI | 221 bar / 3,200 PSI | 12.6 L/min | 178FE | General commercial and mobile cleaning |
| DE250A | 250 bar / 3,625 PSI | 276 bar / 4,000 PSI | 15 L/min | 188FE | Heavier dirt, machinery and industrial cleaning |
| DE200B | 200 bar / 2,900 PSI | 221 bar / 3,200 PSI | 12.6 L/min | 178FE | Rough-site commercial cleaning and frequent mobility |
| DE250B | 250 bar / 3,625 PSI | 276 bar / 4,000 PSI | 15 L/min | 188FE | Heavy-duty construction, fleet and equipment cleaning |
All four models use an electric starting system, PG-series high pressure pumps, 10-meter pressure hoses and 10-inch wheels for practical operation around professional work sites.
The DE200A and DE250A are designed around a relatively compact machine layout that makes transportation, storage, and bulk shipment easier.
For distributors and wholesalers, the compact A-series can be a practical choice when container utilization and handling efficiency are important. The DE200A/DE250A platform has a machine size of approximately 75 × 58 × 65 cm, with loading quantities of up to 84 units in a 20GP and 240 units in a 40HQ, depending on shipment configuration.
Choose the DE200A for regular commercial cleaning or step up to the DE250A when higher pressure and flow are required for heavier contamination.
The DE200B and DE250B are designed for demanding outdoor and commercial environments. Their solid wheels and rugged machine layout make them suitable for moving across surfaces such as grass, gravel, and mud.
The B-series also supports self-priming operation, allowing water to be drawn from suitable open water sources when a conventional pressurized water connection is not available. This makes the series particularly useful for remote construction, agricultural, equipment maintenance, and field cleaning applications.
For the toughest cleaning jobs, the DE250B delivers up to 276 bar / 4,000 PSI with a maximum flow rate of 15 L/min.
Unlike electric pressure washers that depend on access to a power outlet, a diesel-powered pressure washer can operate independently in remote locations.
This makes it especially useful for:
Construction sites
Agricultural fields and farmyards
Machinery yards
Remote maintenance projects
Outdoor fleet washing
Infrastructure and roadwork sites
For businesses that frequently move equipment between locations, diesel power provides greater flexibility for mobile cleaning operations.
Heavy equipment often develops layers of dried mud, grease, oil residue and industrial dirt that are difficult to remove with conventional cleaning equipment.
NEWLAND diesel pressure washers offer maximum pressures from 3,200 PSI to 4,000 PSI, helping users tackle demanding commercial and industrial cleaning tasks more efficiently.
The DE250A and DE250B combine up to 4,000 PSI pressure with 15 L/min flow, making them suitable for applications where both water impact and cleaning volume matter.
Professional pressure washing equipment must handle more than occasional cleaning. It needs to support frequent transportation, outdoor operation and repeated use in challenging environments.
NEWLAND diesel pressure washers feature wear- and pressure-resistant construction, reinforced components, electric starting systems and long high-pressure hoses to support practical day-to-day operation.
Easy access to routine maintenance points also helps operators carry out basic servicing and reduce unnecessary equipment downtime.
Remove caked mud, dirt and jobsite debris from excavators, loaders, compactors, construction vehicles and other machinery.
A diesel high pressure washer is particularly useful on construction sites where electrical outlets may be unavailable or inconvenient.
Use high-pressure water to clean tractors, agricultural machinery, trailers, tools, yards and other farm equipment.
Diesel-powered operation provides greater flexibility for cleaning equipment around farms and remote agricultural locations.
Commercial fleets regularly accumulate road dirt, mud and grease.
NEWLAND commercial diesel pressure washers can support routine cleaning of:
Trucks
Construction vehicles
Agricultural vehicles
Trailers
Utility vehicles
Logistics fleets
High-pressure water can help remove oil residue, accumulated dirt and other contamination from heavy machinery and appropriate industrial working surfaces.
The combination of high pressure and strong water flow helps improve cleaning efficiency when compared with lower-output equipment.
The correct model depends mainly on the level of contamination, required cleaning speed, operating environment and transportation requirements.
Choose a 200 bar model such as DE200A or DE200B when:
You need a commercial diesel pressure washer for regular cleaning.
Most jobs involve mud, dirt and routine machinery maintenance.
Lower machine weight and fuel requirements are preferred.
3,200 PSI maximum pressure is sufficient.
Choose a 250 bar model such as DE250A or DE250B when:
You regularly clean heavily contaminated equipment.
Grease, hardened mud or stubborn deposits are common.
Faster heavy-duty cleaning is important.
You need up to 4,000 PSI and 15 L/min output.
Choose the A-series when compact transportation and storage are priorities.
Choose the B-series when jobsite mobility, self-priming capability and operation over rough outdoor surfaces are more important.
