Why 250 Bar Pressure?

Maximum Cleaning Power

250 bar (3626 PSI) is the highest pressure commonly available in mobile pressure washers. This extreme pressure delivers unmatched cleaning power for the toughest applications:

  • Concrete cleaning - Removes deeply ingrained dirt and stains
  • Industrial degreasing - Cuts through heavy oil and grease
  • Paint and coating removal - Strips old paint and coatings
  • Heavy contamination - Tackles jobs other machines can't handle
  • Professional results - Delivers showroom-quality finish

When You Need Maximum Pressure

250 bar is essential for:

  • Heavily soiled industrial equipment
  • Concrete and masonry restoration
  • Construction site cleaning
  • Agricultural machinery with caked-on contamination
  • Professional cleaning contractors tackling the toughest jobs

Honda GX390 - Industrial Power

Legendary Reliability

The Honda GX390 is Honda's heavy-duty industrial engine, delivering 13HP of reliable power. This is the engine you'll find in professional equipment worldwide - chosen for its legendary reliability, easy starting, and long service life.

Key Engine Features

  • 13HP power output - Drives the high-pressure pump effortlessly
  • 389cc displacement - Large capacity for sustained power
  • Oil alert system - Protects engine from damage
  • Easy starting - Reliable recoil start system
  • Fuel efficient - 6.1L tank provides extended runtime
  • Low maintenance - Simple, proven design
  • Parts availability - Honda parts readily available worldwide

Interpump WS251 - Professional Performance

47 Series Quality

The Interpump WS251 is part of Interpump's professional 47 series - the gold standard for commercial pressure washer pumps. This is the same pump technology used in pressure washers costing thousands more.

Pump Features

  • Brass pump head - Superior corrosion resistance and heat dissipation
  • Ceramic pistons - Exceptional wear resistance for long life
  • Stainless steel valves - Reliable performance in all conditions
  • Triplex design - Smooth, consistent pressure delivery
  • Professional grade - Built for continuous commercial use
  • Serviceable - Easy maintenance and seal replacement

Gearbox Drive - Professional Choice

Why Gearbox Drive Matters

The PM15250 uses an Interpump RS500 gearbox to reduce pump speed to 1450 RPM. This is the professional choice for high-pressure machines because it:

  • Extends pump life - Lower RPM means less wear on components
  • Reduces noise - Quieter operation than direct drive
  • Improves reliability - Less stress on pump seals and valves
  • Delivers consistent pressure - Smoother, more stable performance
  • Enables higher pressure - Makes 250 bar sustainable

Direct Drive vs Gearbox Drive

Direct Drive: Pump runs at engine speed (3400 RPM) - cheaper but higher wear

Gearbox Drive: Pump runs at 1450 RPM - more expensive but dramatically longer life

For professional use at 250 bar, gearbox drive is essential for reliability and longevity.

Return to Tank Unloader System:

Superior Pump Protection

The return to tank unloader valve is the professional choice for high-pressure machines. When you release the trigger, water returns to the tank rather than bypassing internally. This:

  • Reduces heat buildup in the pump
  • Extends seal life significantly
  • Improves reliability
  • Allows longer idle periods between use
  • Protects your investment

Safety Considerations:

250 Bar Safety

250 bar pressure can cause serious injury. Always:

  • Wear safety glasses - Non-negotiable at this pressure
  • Use appropriate footwear - Steel toe caps recommended
  • Maintain safe distance - Start further away than you think
  • Never point at people or animals - Extreme pressure is dangerous
  • Be aware of kickback - High pressure creates significant force
  • Inspect equipment daily - Check for wear or damage

Surface Damage Prevention

250 bar can damage surfaces if used incorrectly:

  • Test on inconspicuous area first
  • Start with wider spray pattern
  • Maintain appropriate distance
  • Avoid painted surfaces unless stripping paint
  • Be cautious on wood, soft stone, and delicate materials

Comparison with Lower Pressure Machines:

PM15250 (250 bar) vs PM21200 (200 bar)

  • Pressure: 250 bar vs 200 bar - 25% more pressure
  • Flow: 15 L/min vs 21 L/min - PM21200 has higher flow
  • Best for: PM15250 = maximum pressure, PM21200 = balanced performance
  • Applications: PM15250 = toughest jobs, PM21200 = general professional use

Which Should You Choose?

Choose PM15250 if: You need maximum pressure for the toughest jobs, concrete cleaning, paint stripping, heavy contamination

Choose PM21200 if: You want balanced performance with higher flow for general professional cleaning

Frequently Asked Questions:

Q: Is 250 bar too much pressure?
A: For the right applications, 250 bar is perfect. It's essential for heavy contamination, concrete cleaning, and paint stripping. For general cleaning, 200 bar might be more appropriate.

Q: Will it damage surfaces?
A: Used correctly, no. Always test first, maintain appropriate distance, and use the right nozzle. 250 bar requires more care than lower pressures.

Q: How does it compare to the PM21200?
A: PM15250 has higher pressure (250 vs 200 bar) but lower flow (15 vs 21 L/min). PM15250 is for maximum pressure applications, PM21200 is more balanced.

Q: Is the Honda GX390 reliable?
A: Extremely. The GX390 is Honda's industrial engine with a legendary reputation for reliability. With proper maintenance, expect 5000+ hours of service.

Q: What maintenance is required?
A: Regular oil changes (every 50 hours), pump seal service (every 100 hours), and annual comprehensive service. We offer full servicing support.

Q: Can I use it with a water tank?
A: Yes, the 3m suction hose allows you to draw from a tank. Perfect for locations without mains water.

Q: Is it suitable for professional use?
A: Absolutely. This is professional-grade equipment built for intensive commercial use. Many professional cleaning contractors rely on the PM15250.
