• The pump discharge head and manifold assembly shall be manufactured from ASTM A48 Class 30 gray iron.
• The motor shall be 2 hp variable frequency, 3 phase designed for installation through a standard 4" tank opening.
• The pump motor shall have a thermal overcurrent overload protector with automatic reset.
• The pump motor assembly shall be clearly marked with pertinent information including Model, Horsepower, Voltage, Phase, and Manufacturer etched into the pump shell for permanent identification.
• Pump to be UL listed as standard for use in fuels containing up to 15% ethanol or methanol with gasoline and 20% MTBE, 20% ETBE or 17% TAME with gasoline and diesel fuel. Optional Alcohol / Gas compatible construction is available which is UL listed in fuel mixtures containing any combination of ethanol or methanol and gasoline, and 20% MTBE, 20% ETBE or 17% TAME with gasoline.

• The pumping unit shall not incorporate any flexible diaphragms. All sealing shall be accomplished with O-rings or UL recognized fiber gaskets.
• The pump shall operate with a variable frequency controller. The controller shall be designed to vary the speed of the motor to provide constant flow to up to 8 car fueling nozzles operating simultaneously at a predetermined flow rate of less than 10 GPM (38 LPM) to meet federally mandated "Spitback" control. The controller shall have the following additional functions :
  • Dry Run Protection. Accomplished by continual monitoring of motor power consumption. The controller shall turn the motor off when the tank is pumped empty.
  • Report Abnormal Operating Conditions. The controller shall report the following abnormal operating conditions by means of a red flashing light on the face of the controller, or by connection to a computer through an RS 485 communications port.

• Manual Reset Button . The controller shall be equipped with a manual reset button, which is pressed upon correction of any of the above faults.
