INLET & MOUNTING DIMENSIONS When installing units that contain a high alcohol product (e.g. E100). Confirm that the plumbing is designed to handle an alternative fuel. For multi- hose units, piping must align with the footprint. Alternative fuels, such as E25, E85, and other ethanol blends, may require special piping materials or components. Consult the piping manufacturer to determine if the piping material, fittings, and connectors are compatible with the alcohol-blended fluid being used.

12 Bennett T75 Operation, Service, & Parts Manual Operation SECTION 3: OPERATION OPERATION The following section describes each of the main components of the T75 pumping unit and the interface characteristics at each component. Refer to the diagram on the next page for item locations. For any questions, please contact Bennett Technical Support at 1-800-423-6638. The pump assembly has the following main components: (See Figure 9 for numbers in parenthesis.)  Body (1)  The inlet is designed to accept a triangular inlet flange with a 3-hole bolt pattern.  Cover (2)  The Flanged Outlet is used for direct meter mounting  The Tubular Outlet is used for remote meter mounting (as shown on page 6)  Filter (3) located in the horizontal position. Note: The filter cover includes a pipe plug to drain the pump.  An optional Inlet Check Valve (19) is available to hold product in the suction line when the pump is turned off. It maintains a vacuum in the line preventing fuel from leaking through a loose joint into the ground.  Rotating Pump (4) with Radial Carbon Blades  The Throwout Rings (5) maintain contact of the blades to the stator.  The Stator (6) turns clockwise and is tightly fitted in the pump body.  The Rotor (7) is made of cast iron with a chrome-plated shaft.  The Self-Lubricated Bearings (21) are used to prevent seizure when tank is pumped dry.  The Cover (8), also of cast iron, encapsulates the rotor and the stator.  An Air Elimination Assembly (9), a patented fully static device, uses a vortex effect.  The insert (10) starts spinning the fluid.  The foam and the air pass through the Tube (11) and evacuated through the Orifice (12).  A Drain Line Eliminator (13) or atmospheric chamber of 1.2-gallon (4.5 liter) capacity.  The Float Valve Assembly (14) provides for the recovery of liquid from the chamber, while air is evacuated through the Vent Tube (15).  A Non-Return Float (20) seals the atmospheric chamber when the pump is turned off to prevent flooding and spilling out onto the driveway.  A Bypass Valve (16) is used to limit the maximum working pressure.  Its cover includes a device to adjust the bypass pressure (optional in USA)  A Control Valve Assembly (17) assures that all downstream hydraulic components are filled with liquid. This valve has a Relief Valve (18) to relieve excess pressure. NOTE: A diaphragm operated preset valve is available as an option.

THEORY OF OPERATION See Figure 10 for numbers in parenthesis.  The product is drawn from the underground storage tank through the strainer screen of Filter (1).  The Rotary Vane Pumping Unit (2) pressurizes the fluid.  Product enters the centrifugal Air Separator Assembly (3). Any air present is forced out the air tube along with a small amount of liquid into the Atmospheric Chamber (4).  Product collected in the atmospheric chamber is returned to the pump intake across the non-return float when the liquid level in the chamber lifts the float and valve assembly from its Seat (5). Any air is then vented to the atmosphere through the vent tube.  Air free product leaving the air separator opens the Control Valve (6) and is pumped to the meter. The control valve includes a built-in Relief Valve (7) which relieves excess pressure caused by hot weather expansion.  Product passes through the meter where it is accurately measured, then through the hose and nozzle into the vehicle being fueled.  Whenever the nozzle is not fully opened, some liquid is relieved into the pump intake through the Bypass Valve (8).

Use the table in each section to determine the cause and solution. For any additional questions, please contact Bennett Technical Support at 1-800-423-6638. PROBLEM 1: THE MOTOR STARTS BUT THE PUMP DOES NOT DELIVER FUEL. Refer to the table below for a description of various causes of the problem and the solution. Cause Solution The fuel supply is below the suction stub in the storage Fill the storage tank. tank. The vent pipe is plugged in the storage tank. Clean the vent pipe. The strainer screen or filter assembly has an obstruction. Remove obstructions from the screen or filter assembly. The bypass valve is not seating properly due to the wear Check the valve for an obstruction causing the valve to stay open, and/or replace or obstruction. the bypass valve. The v-belt is loose or broken. Adjust or replace the v-belt. There is an obstruction in the atmospheric float valve. Clean the float and valve area. Check for swelling and binding in the linkage. The pump is out of prime. All fuel drained out of suction Check for a faulty foot valve in the storage tank or a faulty check valve in the line due to fault line check or foot valve. suction line. The suction line is leaking. Start the pump and open the nozzle. If bursts of air are felt while holding a finger on the vent tube, the suction line is damaged. Repair or replace. The intake line, foot valve, angle check valve, or vertical Connect a vacuum gauge to the ¼” plug on the filter cover. Turn the pump on and check valve has an obstruction. open the nozzle. A reading of 15 or more inches of mercury with no flow indicates a complete blockage in the suction line. Clean the line or replace.

If the liquid is drawn out of the supply lines. container when the opposite pump is operated with an open nozzle, the line * Not recommended check valve is faulty. Replace the check valve. PROBLEM 2: THE PUMP RUNS BUT DELIVERY IS SLOW. Refer to the table below for a description of various causes of the problem and the solution. Cause Solution The fuel supply level is low. Fill the storage tank. The storage tank vent pipe is partially obstructed. Clean the vent pipe. The strainer screen is partially plugged. Remove obstructions from the screen or filter assembly The pump bypass valve is not seated properly. Remove and clean the strainer screen. The V-Belt is loose. Adjust the V-Belt The motor voltage is too low. Check the power supply voltage. Check for too many pieces of equipment on one electrical line. A blade or blades in the pump are worn or broken. Check the blades and replace if necessary. An automatic nozzle has been installed. Delivery speed will be reduced by 10-25%. If maximum speed is desired, replace with a manual nozzle. The motor is defective. Inspect the motor for loose connections. If no loose connections are found, the motor is defective. Repair or replace. There is a slow leak in the suction line. Start the pump and open the nozzle. If bursts of air are felt while holding a finger on the vent tube, the suction line is damaged. Repair or replace. The suction line is obstructed or the foot valve, angle, or Connect a vacuum gauge to the ¼’plug on the filter cover.
