| Other | When Sodium Hypochlorite breaks down, it forms Hypochlorous Acid and a Hypochlorite Ion. Sodium Hypochlorite breaks down when it comes in contact with organics, a temperature rise, high or low pH, time passing and ultraviolet rays. The Hypochlorous Acid is REACTIVE to the Fiberglass mixed in with the Polypropylene body of the pump. The Fiberglass improves the integrity and strength of the pump manifold but is ultimately the inherent time bomb for roof washers using Sodium Hypochlorite. The result is pin-prick size holes in the pump caused by the degradation of the strands of Fiberglass by the Hypochlorous Acid. (http://www.lenntech.com/processes/disinfection/chemical/disinfectants-sodium-hypochlorite.htm) Furthermore: Please note that the polypropylene or nylon bodied pumps or wetted components such as the head of a pump are fiberglass or glass reinforced. SH gas degrades the fiberglass or glass and causes pin prick size holes in the pump. The pump is considered disposable at that time. Most of the seals on these stock pumps are buna instead of FKM. An example of buna can be related to the standard black o-rings and NOT SH resistant or heat resistant compared to the brown o-rings which are chemically and heat resistant. O-Rings Buna: In pressure washing and the related industries, is the black o-ring used inside the coupler of socket allowing for a leak-proof seal. Buna is also known as Nitrile or Buna N. If using oxidizing chemicals such as sodium hypochlorite or bleach, do not use buna. Buna is not resistant to SH or heat. |

How a AODD works: Two diaphragms connected by the diaphragm rod work in unison to create the liquid motion of the pump. While one side is in suction mode the other is in discharge mode. As a diaphragm moves inward it creates suction. This suction motion causes the balls to move towards each other. As this happens the top valve closes and the bottom valve opens. This allows liquid to enter the chamber through the bottom port.
As the diaphragm moves outward the discharge motion causes the balls to move away from each other. As this happens the top valve opens and the bottom valve closes. This allows liquid to exit the chambers and discharge through the top port. This process constantly alternates between the two chambers to create a continuous cycle. The pump diaphragms are driven by pressurized air that is directed left and right by the movement of the main air valve.
Here’s how it works: When air pressure is applied to the pump, the main air valve moves up and down. When the main air valve is in the down position, air pressure is diverted to the right diaphragm. At the same time, exhaust air from the left diaphragm passes through the shuttle and shuttle plate, and exits the rear of the pump. When the main air valve is in the up position, air pressure is diverted to the left diaphragm while the right diaphragm is exhausted. This process constantly alternates between the up and down position to create a continuous cycle.
