Built for Professionals

The JRV28G32 has a triplex plunger design, a step up from axial pumps found in consumer grade units. Triplex pumps are designed for heavier use, smoother operation, longer life and better efficiency under sustained loads.Delivers 3,200 PSI at 2.8 GPM. This pump has the power and flow for demanding cleaning tasks. From stripping paint and washing heavy equipment to deep cleaning large surfaces the JRV28G32 is built to tackle tough jobs.

The ceramic plungers provide exceptional wear resistance and thermal stability, outperforming stainless or tempered steel plungers. With a brass manifold the pump resists corrosion, ensures reliable sealing and long lasting durability.

Integrated Features

This pump has a built-in unloader which regulates water pressure and provides bypass functionality when the spray trigger is released. This makes operation safer and helps extend pump life by preventing pressure spikes.

A fixed chemical injector is integrated into the system so you can easily apply detergents for jobs that require more cleaning power. Switching between detergent and rinse is as simple as changing spray tips.

The 3/8” brass quick-connect discharge fitting (85.300.103) provides secure, leak-free hose connections for frequent use.

Protection and Maintenance

The JRV28G32 is designed with protection features to prevent overheating and extend pump life. The included thermal relief valve (85.300.022) prevents heat buildup during extended bypass by purging hot water and replacing it with cooler water.

The pump requires 7 oz of 30W non-detergent oil to keep moving parts lubricated and running smooth. Routine checks and oil changes will maintain long term reliability and the pump’s sealed construction keeps contaminants out.

With a maximum water inlet temperature of 140°F (60°C) the JRV28G32 can handle higher temperature inputs than most residential pumps giving it more flexibility and resilience in demanding conditions.

Applications

The AR JRV28G32 Pump is a professional grade solution for both residential users who need more power and commercial operators who demand reliable output. Its flow, pressure and triplex durability makes it perfect for:

  • Driveways, Sidewalks and Patios – Blasting away grime, mold and oil stains.

  • Construction Equipment – Cleaning dirt, mud and grease from machinery.

  • Vehicles, Fleets and Boats – Power washing trucks, trailers and marine equipment.* Agricultural Tools and Barns – Cleaning farm equipment and structures.

  • Industrial Surfaces – Heavy-duty maintenance cleaning.

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
