Using a Pump to Supply A Pressure Washer - Cleaning Equipments

For mobile cleaning applications, pressure washers may be directly fed from a tank without using a pump to push the water from the vessel to the machine.  However, direct drive pressure washers must be kept close to the tank and will be less likely to cavitate if the machine is below the tank level.  Belt drive and gear drive machines are capable of pulling from a tank even more effectively and can be located slightly higher than the water source.  Its always best to locate the pressure washer as close to the water source as possible and lengthen the high pressure hose to reach the cleaning location.

While we have seen a few customers have success using a pump to supply their pressure washer from a tank, it doesn’t happen often and we do not recommend using that type of system.  In many cases, supply pumps have a fluctuation in their flow rate and this makes them prone to cavitating the high pressure pump.  Turbulence in the inlet flow on the pressure washer causes cavitation just like starving the pump or introducing air into the inlet stream.  As a result of this, we neither recommend nor sell equipment for pumping water from a tank to a pressure washer without having an additional reservoir or tank for water right at the machine.

What is a pressure washer? - Vacuum Cleaner

A pressure washer is a mechanical device that uses a pump to generate a high-pressure stream of water to clean surfaces. The pump is typically powered by a gasoline engine, an electric motor, or a diesel engine. The pump is a positive displacement pump that forces a specific amount of water flow from the outlet.  By restricting the flow with the nozzle, much like you do by placing your thumb over the end of a garden hose, the pressure washer produces pressure. Without the nozzle the impact of the water from the end of the pressure washer hose is similar to that from a garden hose. The narrow diameter of the nozzle increases the water's velocity and, consequently, its impact and cleaning power. The smaller the nozzle orifice, the more pressure is potentially produced. However to produce greater pressure, more horsepower is required to force the water through the smaller hole. Each pressure washer calls for a specific size nozzle to match the flow of the pump and the horsepower of the motor. Putting too small a nozzle on your pressure washer strains the components and may cause excessive wear to the machine; too large a nozzle sacrifices cleaning power.

All pressure washers produce pressure and flow. Both are important to the cleaning process. Most pressure washers also provide a method for dispensing soap or detergents, either under low or high pressure. The proper use of soap is often key to the cleaning process. Hot water pressure washer are equipped a burner system to continuously heat the stream of water, further aiding the aiding the cleaning process. Most hot water pressure washer can generate wet steam of approximately 240 degrees F, by turning down the pressure to around 150 PSI. There also true steam cleaners that generate a dry steam of approximately 320 degrees F at 150 PSI. Understanding the basic concepts of pressure flow and cleaning units will help you pick the right pressure washer for the cleaning job at hand.

Pressure and flow
Pressure washers use the impact of the water to break the bond of the dirt to the surface you are trying to clean; the higher the pressure, the greater the impact. The type of nozzle you use makes a huge difference in how much impact your pressure washer creates. A zero degree tip gives you the full impact of your pressure washer but is almost useless for cleaning because it hits such a small area. A 15 degree nozzle increases the area you can clean at one time, but reduces impact by 70%. A 40 degree increases the surface area cleaned further, but has 88% less impact than a zero degree nozzle. This is why a turbo nozzle is so effective; for it is a 0 degree nozzle rotating thousands of times a minute creating a 25 degree cone of full impact.
The amount of water, or flow, a pressure washer puts out makes a big difference in cleaning. The flow is what carries the impact to the surface. The more flow, the more impact; there is a direct relationship. A 13 HP pressure washer putting out 4000 PSI at 3.5 gallons a minutes flow has one third less impact than a 20 HP unit putting out 3,500 PSI at 5.0 gallons per minute. Moreover, flow is what is needed for effective rinsing. This is especially true when cleaning large open surfaces, like driveways; or quickly rinsing vehicles in truck washing operation.

Cleaning units
A pressure washer pump creates a positive water flow, and by restricting that flow at the nozzle creates pressure. The more horse power driving the pump allows more flow to be pushed through the pump and the more pressure to be created at the nozzle. For a given amount of horsepower you can have only so much pressure and flow; there is a tradeoff. Most people focus on pressure (PSI), but you really need to consider both pressure and flow. One way of comparing pressure washers is to use the measure of “cleaning units”. To calculate cleaning units, multiply the pressure times the flow of the pressure washer. All other things being equal (i.e. chemical use and heat) a unit with higher cleaning units will clean better than a unit with lower cleaning units.

Cleaning unit application guidelines
Home use, light duty: 2,000 to 3,750 cleaning units.
Medium duty: 3,800 to 7,500 cleaning units
Heavy duty: 7,600 to 15,000 cleaning units'

The measure of cleaning units is a good way to compare the power of one pressure washer relative to another, with the following proviso. When two pressure washers have different pressure and flow specifications, but the cleaning units are equal, remember the unit with the higher pressure unit will make a rotary nozzle work better, while the higher flow unit will rinse better and make flat tip nozzles work more effectively. With that in mind, the following guide can be used on how much pressure and flow is needed to perform certain tasks. Some of these tasks may require a rotary Dirt Killer nozzle as well if you are using the minimum PSI. The minimum specifications are what are required to get the job done. Having more pressure and flow will make the job go faster. The column marked preferred CU shows how much cleaning power is required to get the job done more quickly. (CU means Cleaning Units: cleaning units = Pounds per Square Inch of pressure (PSI) times Gallons Per Minute of flow (GPM).

How to Use a Steam Vacuum Cleaner

A steam vacuum cleaner is a very important appliance in a home since its function of extracting steam to kill bacteria while cleaning thoroughly is highly appropriate especially in the case of carpets, floors, soft furnishings and upholstery. The moisture and any residuals and dirt is sucked up by the steam vacuum cleaner.

Step 1 - Read the Instructions Carefully

Although the function of a steam vacuum cleaner is the same for all models, there will obviously be a number of variations from one to another. Hence it is very important to read the instructions accompanying your steam vacuum cleaner carefully and in case you do not fully understand something make sure to ask the supplier or manufacturer. Keep in mind that incorrect use in some way or another may cause the stain you are trying to clean to penetrate further in the fabric, or else you may cause the vacuum cleaner some sort of damage.

Step 2 - Fill with Water and Soap if Desired

A steam vacuum cleaner operates with water. Remove the container where water needs to be placed for the steam cleaner mechanism to operate. Fill this container with water making sure not to exceed the maximum level. Some people also opt to use special soap products made for steam cleaners so as to clean better, remove stains and leave a pleasant fragrance. In such a case make sure to use a good quality product and follow the directions on the package. When ready carefully reinstall the container back in its place inside the steam vacuum cleaner.

Step 3 - Plug the Steam Vacuum Cleaner and Start Cleaning

Plug the steam vacuum cleaner to the nearest or most convenient electrical source and start to rub down on the carpet or other surface with it. It is best to move it in such a way so as to create regular strokes in the same direction, and then alternate the movement. This will ensure more thorough cleaning of the carpet fibers. On the first stroke press the lever or button which will release the steam onto the carpet. When changing the direction release the mechanism which will scrub the carpet and suck the moisture, residuals or dirt.

Step 4 - Repeat the Process

Move little by little, treating small areas at a time until you have cleaned the whole area of the carpet or surface. In areas where there is a persistent stain, you may need to spend more time on this area and go over it more than once so as to scrub more effectively and hopefully manage to remove the stain.

Step 5 - Allow it to Dry Well

Once finished allow the carpet to dry well. It is best to open a window to accelerate the drying process and make sure you avoid walking over the carpet or surface you have just cleaned.

Step 6 - Discard Any Water

Make sure to discard any water or soap that was not used, wipe the container dry and reinstall it in the steam vacuum cleaner.

By following these steps you will deep-clean your carpets or other upholstery effectively.

Cleaning, Sanitation in Food Industries

The primary objective of cleaning in Food Industry is to remove the residue in the machinery on which bacteria grow and to rid all the surface areas including walls of any physical impurities. 

Efficient methods

 The most popular and often used method to remove surface deposits is to clean with a Pressure Washer of about 15 lpm flow & 150 bar pressure. The size and type of pressure washer will be determined by the area and type of machinery being cleaned and the level of cleanliness required. The type would normally be a hot water pressure washer with a steam nozzle option for deeper cleaning like ‘HOT WATER MODEL – 6970’ from Astol Cleantech (P) Ltd.

Alternatively, a standalone Dry Professional Steam Cleaner generating about 9– 2 bar steam pressure might be more appropriate for some applications. This cleaning equipment is available as static or portable unit but the selection of the correct unit is determined by the requirement of the equipment used in the process. A preferred one shall be a Mobile Unit for its convenience to be carried to the point of use – the applications surfaces. Model steam cleaner supplied by Astol Cleantech is ‘GV KATLA.’ 

Customized Cleaning

The processes followed in food industry are normally same every day and therefore, the cleaning requirements are also more or less likely to be similar. The procedure for cleaning food industry machinery is to clean surfaces with the appropriate chemicals followed by rinsing and applying a sanitizing agent to reduce microorganisms to a safe level. To achieve the correct level of hygiene, it is better to install a customised system which allows the process to be carried out to the correct standard. - See more at: Click here

Pressure Washing Techniques For a Deep Clean

While the success of many household cleaning tasks simply depends on choosing the right cleanser for the job, there are some cases where the labor involved in removing a film or stain is just too much. Perhaps the stain is bound too tightly to the surface of what you want to clean, or the affected area is simply too large for vigorous hand scrubbing to be a viable option. If this scenario sounds familiar, your solution might require a bit more power.

Common Pressure Washing Situations
You may have seen professionals pressure washing, or maybe even done it yourself. For handling enormous cleaning tasks like buildings, walls, parking areas, heavy equipment, or even statues, a pressure washer is often the right tool for the job. Pressure washing is the preferred cleaning method for removing pollution and fuel emission residue on structures in urban areas. It is also an excellent method of removing mineral, lime, and hard water deposits. Homeowners, especially those who like to work on their own cars, will find that pressure washing is great for grease and oil stains in the garage or driveway; it can even remove graffiti!

DIY vs. Professional Pressure Washing
There is most likely a home improvement center or hardware store in you area that will rent you a pressure washer (or at least point you in the right direction to find someone who will). Make sure that you talk to the people you rent the machine from about the task you plan to use the power washer for to see if they have any advice about technique or particular cleaning solutions you can add to make the operation go smoother.

In professional hands, this is an efficient, effective cleaning alternative that will often save money over more labor-intensive methods. If you've never used a pressure washer before and are unsure of how they work, you may consider hiring a professional for the job. Because of the amount of power involved in pressure washing, an inexperienced user can unintentionally cause a great deal of damage. Situations like cleaning windows or siding with a powerwasher require a delicate and skilled hand, so even if you are confident in cleaning stains from concrete in your driveway, you might consider hiring someone for these kinds of jobs.

Powerwashing Techniques
Power or high-pressure cleaning is a directed blast of internally heated water, often discharged at five gallons per minute, under up to 3,000 pounds per square inch of pressure. For specific cleaning and stain removals, certain chemicals or solvents are added. For specific or environmentally safe cleaning needs, there are several other blasting methods:

With soda blasting, there are the advantages of being environmentally safe, and no pre-masking is required. It cleans multi-layered surfaces, and it is non-corrosive and safe to perform around food equipment.

Sandblasting is intended for jobs that require some stripping and abrasion.

Dry ice blasting shoots dense dry ice pellets that turn to a harmless gaseous substance on impact. This option leaves an instantly dry surface, and it is also safe around food equipment.
