Pressure Washer Products is proud to offer the All-Flo 1/4" Kynar air diaphragm pump assembled in the United States of America for PWP for use specifically with soft wash chemicals. This is a great pump for those who need to pre-treat and post-treat. This is the only pump on the market that will allow the operator to fully control the flow by using any nozzle size suitable for the job. The fleet washer, soft washer, chemical applicator, or roof washer can choose to use any nozzle orifice of 1.0 to wide open at 90 in. We recommend orifices from 5-12 in spray patterns ranging from 0 to 25 or sometimes 40 for best results.

Viton diaphragms are not the best choice because of the following reasons according to all-flow:  Santoprene and other thermal plastic elastomers (TPE) will have a very long flex life due to the nature of the material. This is especially apparent when comparing them to form and PTFE diaphragms, which tend to have a low flex life. When selecting a diaphragm, chemical compatibility and the natural flex life should be considered. In most cases, a “B” rating Santoprene or another type will outlast an “A” rated km (Viton) or PTFE diaphragm. This is because both the “A” and “B” rated diaphragms will normally fail due to their natural flex life before they experience chemical issues. PTFE should predominantly be used when a type is not chemically compatible with the process fluid, and FKM (Viton) is traditionally used for high-temperature applications that go above the other materials' maximum temperature limits. In short, Santoprene has a high flex life, and (Viton) has a very low flex life with flex life being its weakness.

  • Most users pair this 5.7 GPM 'Cadillac of AODD pumps' with 200' of 3/8" or 1/2" ID chemical hose, a 1/2" PVC ball valve or chlorine gun and a 4312S full frame Titan hose reel.

    PWP recommends adding SLO-MO 'Original' soft wash surfactant to your recipe to save time and money.  When SLO-MO is added to your recipe, it 'grabs on' to the chemical and helps to work it into the vertical or horizontal surface. Some say that their mix is stronger. However, nothing can increase the strength of sodium hypochlorite. Sodium hypochlorite can only be made more effective by the addition of an excellent, biodegradable surfactant. Every SLO-MO user reports using fewer chemicals by making fewer passes and losing fewer chemicals to run off.

    Before you consider any other brand other than All-Flo, ensure that you are buying a comparable pump. This 1/4" Kynar-bodied pump with PTFE diaphragms is 5.7 GPM!

    The main advantages of using an All-Flo air diaphragm pump for soft washing, roof washing, chemical application, and transferring chemicals to your trailer or truck rig are listed as follows:

    The All-Flo 1/4" Kynar air diaphragm pump is designed to handle the needs of soft washer chemicals.

    The 1/4" All-Flo pump is a perfect choice for residential and heavy-use commercial cleaning chemical applications as it allows the operator to control the flow to prevent run-off, over or under-saturation, prevent plant kills or damage to delicate surfaces as well as saving money on the wasted chemical.

    The All-Flo air-operated dual diaphragm pump is offered with a 5-year warranty.

    The operator can use a pump to clean and transfer chemicals to the truck or trailer rig instead of hand pumping or purchasing another pump to do the job.

    The operator can use any applicator such as a 1/2" PVC ball valve, garden hose spray nozzle, or pressure washer gun connected to a minimum 200' of 3/8" or 1/2" ID chemical hose to apply the chemical.

    All-Flo pump owners must use the correct regulator/filter (AFRS) to protect the pump. Install the regulator per the directions included with the packaging. The arrow on the regulator must point to the pump or the regulator will release air. Drain and clean the filter daily. Using the filter/regulator and gauge will prevent over-pressurization of the pump when set to 80 PSI. The filter should be cleaned daily. It can be installed anywhere on the air hose leading to the pump but better if installed closer to the compressor. 

    Install a water separator between the regulator and the pump using a hex nipple or another length of air hose. Purchase the water separator (Motorguard or M45 online anywhere)

    ***Must drain the bottom ports on the compressor tanks daily*** 

    Chemical hoses assembled by pressure washer products do not need or use hose clamps.

    Each All-Flo pump is backed by a 5-year warranty and tested before shipment

    Your All-Flo double diaphragm pump is warranted to the original user against defects in workmanship or materials under normal use (Rental use excluded) for five years after the purchase date.

I recently purchased a pressure washer from Pressure Washer Products, and the experience was fantastic from start to finish!

The quality of their products is top-notch.. Highly recommended!

Kerolos Mamdoh

The best pressure washing store hands down. Rex the owner and his team have a wealth of knowledge about the industry. Lori is always there to help you with what you need. I’ve saved alot of money over the years through them because they help to educate you on what products and equipment are best to buy for your specific set up/washing goals. Other places attempt to drain your bank account if you let them. Not here, that’s why they have customers for life

Jared Policandriotes

I recently bought a surface cleaner from PWP, and it's been a game-changer. Lori helped me find the right tips for my machine, and the results have been fantastic. Thanks, Lori!

Sheriff Khalifa

Lori was very helpful and got us out surface cleaner and recommended what tips to match our machine. Runs fantastic. She also recommended a chemical injector to try on our trailer and it has been another great upgrade. Lori knows her stuff and the price and shipping was reasonable!

Brent Batton

I am a new customer to this business and have been here three times. Each time I have received fantastic customer service. I am glad there is actually a local business around that deals specifically with pressure washers. Highly recommended.

Doug Williams

I love this store. Laurie and Rex/ Family have been a huge help in understanding aspects of the equipment and tools we use in this industry. I’ve learned lots from them. Also the pricing and amount of supplies the store has to offer is perfect for a quick trip to load up and head out.
