Introduction For The 3000 Series Electronic Commercial And Retail Dispensers - Bennett 3000 Series Installation Manual

Go Pump Commercial 3000 Defueler Electronic and Mechanical Dispensers Specification Sheet
Commercial (industrial) volume only display
The "defueler" dispenser operates differently than most suction pump dispensers that you may have
seen in the past, in that it is designed to remove fuel out of a vehicles gas tank and return the fuel to the
underground storage tank. This means that the hose or defueling "wand" is connected to the self
contained pumping units "inlet", and the fuel drawn out of the vehicle passes through the meter and back
to the underground tank through the underground piping. All "defuelers" are self contained (suction
pump) units. There are no remote (submerged pump) models. The "defueler" is available as either the
3700 series electronic or 3100 mechanical dispensers.
This "defueler" is only available in the self contained, single hose, low hose model. There are some
special installation considerations with this type of application, such as, but not limited to:
1) Dispenser requires a double poppeted impact valve
2) Underground tank requires overfill protection and a working vent pipe
See the information contained in this manual for proper installation.
