PureFlow® Technologies has replacement motors and complete 4G-HD pumps available. 

 

The replacement 4G-HD pumps fit all of the larger Industrial FPII-150 & 200 AirDog® Fuel Air Separation Systems and the smaller FPII-125 systems for gensets and other small industrial applications. These pumps are extremely quiet and have a expected service life in excess of 18,000 hours.

 

The new AirDog® 4G Industrial fuel pump includes:

A mounting bracket & 4 ea 5/16" counter sink mounting screws, 2 ea. #8 x orb fittings, 2 ea.  orb x  3/8"  NPT adaptor bushings   



Fuel Filters & Water Separators

 

PureFlow® Technologies wants to see you make the best return possible from your trucking enterprise. The AirDog® with Fuel Preporator® technology does this for your engine. However, fuel filters are still needed and still require service.

 

The AirDog® fuel filter is the highest quality and most long lived filter available. The media is made of 6 micron Microglass®. This is the same media as used in final filters on fuel islands across the nation, except for the 6 micron. When combined with the power of the 4G-HD pump, have a useful life of up to 30,000 miles or more unless you find that “bad load” of fuel.

 

The AirDog® water separator utilizes a wire screen, 100 mesh media. This allows virtually unrestricted flow (Vacuum feed) from the tank to the AirDog®. Although the wire screen is in a spin-on canister, it can be removed and cleaned. It only needs to be replaced when it is too contaminated to clean or damaged.  

 

Why AirDog® Fuel Filters & Water Separators Last Longer Than Filters on Vacuum Feed Systems! 

 

The AirDog® provides a Net Positive Pressure Head to the transfer pump on your engine through our new 4G-HD pump. This pump is powerful and will continue to flow fuel through a filter long after the filter on your engine has reached its limit under vacuum feed. Fuel flow to the transfer pump on your engine is created by atmospheric pressure differential (Vacuum Feed) and has a limited flow that gives out easily. That limit is reached when the restriction level (vacuum) reaches about 10-12 in hg. That is a pressure differential, when converted from barometric pressure to pounds per square inch, of 5 to 6 PSI.

 

Internal filter pressures on the AirDog® can reach 35 to 40 PSI and more. The Microprocessor Fuel Filter Monitor was designed to let you when to change the filter to get the complete life out of the filter. Through the use of an indicator light on the dash, you know exactly when to service the water separator and when to change the filter. No more guessing when to change a filter! No more loosing fuel economy from a filter that plugged prematurely from a bad load of fuel! No more changing a clean filter just because a mileage point was reached!

How Does Air Become Entrained In Diesel Fuel?

 

As in all liquids, air becomes entrained in diesel fuel from sloshing and agitation! Air can be on the surface of the fuel in the form of foam or it can be in the bulk fluid in the form of tiny bubbles. Entrained Air is an issue of an "in use" engine in operating equipment!

 

What is Pump Cavitation?

 

Pump cavitation, simply put, is the pump not having enough pressure flow, or "Net Positive Pressure Head" of fuel coming into the inlet to completely fill the vacuum chamber of the pump.

 

Diesel fuel, as is true with all petroleum base liquids, will give off vapor when subjected to a vacuum. The amount of vapor depends upon the level of vacuum and temperature.



 

How Does Fuel Filter "Restriction" Effect Cavitation?



In the diesel engine industry, "fuel filter restriction" is a term that refers to the vacuum level at the inlet to the transfer or lift pump. It is measured in inches of mercury (in hg).

 

As the filter plugs with use, it further restricts the flow and increases the vacuum level in the pump.

 

The amount of vapor produced depends upon the level of vacuum.


 

What Else Increases Cavitation and Vapor? 

 

As the fuel levels in the tank(s) goes down as the fuel is burned, the "Dry Suction Lift" increases. This reduces the flow, increasing the vacuum.  

 

Operating at higher altitudes, where atmospheric pressure is less, reduces the fuel flow and increases vacuum. For example, at Denver,  atmospheric pressure  is about 17% less than at sea level and at Eisenhower Tunnel, it is approximately 32% less. Having less pressure to drive the fuel from the tank to the transfer pump, reduces the flow and increases the vacuum levels.

 

Higher fuel temperatures cause more vapor to form than cooler fuel under the same vacuum!
