Pressure Washer Products is proud to offer the All-Flo 1" Kynar air diaphragm pump. The 1" Kynar bodied pump is engineered to exceed the needs of softwashers  and endure heavy daily use of softwash chemicals. This is the only pump type on the market that will allow the operator to control the flow by using any nozzle size suitable for the job. The softwasher or roof washer can choose to use any nozzle orifice of 1.0 to wide open at 90. This softwash pump is truly a beast! Choose this pump for the most challenging softwash application requiring speed, control and reliability or the daily residential roof cleaning job.

Viton diaphragms are not the best choice because of the following reasons according to All-Flo:  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 FKM and PTFE diaphragms, which tend to have a low flex life. When selecting a diaphragm, the chemical compatibility and the natural flex life should be considered. In most cases, a “B” rated Santoprene or other TPE will outlast an “A” rated FKM (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 TPE 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 FKM (Viton) has a very low flex life with flex life being its weakness.

Use anti-seize when assembling the stainless components on this pump.

Most users pair this 'Cadillac of softwash pumps' with a minimum of 200' of 5/8" or 3/4" id chemical hose, a 1/2" or 3/4" SCH 80 PVC ball valve or chlorine gun, a 4322S full frame Titan hose reel, a Tribanger or JROD and nozzles to reach about 45'-70' and beyond on a roof.  

Purchase the flange kit to allow you to connect the hoses to this pump.

Air inlet ¼"
Flanged liquid inlet 1"
Flanged liquid outlet 1"


Maximum flow 41 GPM 
Maximum air pressure 120 psi   Do not run this pump at 120 psi. Like your tires, run it lower. Set the regulator (AFRS) pressure on the airline to 80 psi maximum.

Requires a minimum of 9 gas hp or larger to maximize total capacity of this pump. However, higher vertical distance can be reached and greater efficiency by increasing speed when a larger compressor is paired with this pump. In this case, yes, bigger is better.

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

  • The All-Flo 1" Kynar air diaphragm pump, AFKE10, is designed to handle the chemical needs of softwashers to up to 43 gallons per minute.
  • The 1" All-Flo pump is an elitist choice for residential and commercial cleaning as it allows the operator absolute control of flow in preventing run-off, over or under-saturation, preventing plant kills or damage to delicate surfaces as well as saving money on wasted chemical.
  • The All-Flo air operated dual diaphragm pump is offered with a 5-year warranty.
  • The operator can use pump to clean and to transfer chemical to the truck or trailer rig instead of hand pumping or purchasing another pump to do the same job.
  • The operator can use any applicator such as a 1/2" or 3/4" PVC ball valve, garden hose spray nozzle or chemical gun connected to 200'-300' of 5/8" or 3/4" ID chemical hose to apply softwash chemical to a surface.

Protect your pump by using the correct filter/regulator and gauge set between 80 psi maximum. Drain and clean the filter daily. Using the filter/regulator and gauge will prevent over-pressurization of the pump. It can be installed anywhere on the air hose leading to the pump but closer to the compressor is best. We offer a special, higher flow regulator with a mount for this pump. We recommend using one of our high quality 3/8" ID air hose assemblies to connect the regulator and desiccant filter to the air valve of this pump to ensure a long life.

We recommend using 5/8"- 3/4" id chemical hose available in custom lengths of our yellow, blue or red Flex Tech RT or Kuri Tec lightweight chemical hose. Some operators prefer to use 3/4" ID hose. The yellow ag, Flex Tech RT and Kuri Tec are *A* rated* for use with all softwash chemicals. The most common length is a continuous 200' piece with crimped on hose barbs with 316 stainless steel using one of our hydraulic crimpers in house. Chemical hoses assembled by pressure washer products do not need or use hose clamps.
