Standard for Power-Operated Pumps for Petroleum Dispensing Products

1.1   This Standard sets forth minimum requirements for electrically-, hydraulically-, or pneumatically-driven power-operated pumps for use with petroleum products in the following applications:

1. Self-contained flammable liquid dispensing devices and submerged pumps used in storage tanks that provide the petroleum product to remote control flammable liquid dispensing devices. They are intended for operation at discharge pressures of 50 pounds per square inch (psig) (345 kPa), or the marked maximum discharge pressure rating, when less, with the ambient and liquid temperature within the range of minus 20°F (minus 29°C) – 125°F (52°C).
2. Flammable liquid dispensing systems to transfer the petroleum product from a tank or container to a vehicle or another container. They are intended for operation at the marked maximum discharge pressure, or less, with the ambient and liquid temperature within the range of minus 20°F (minus 29°C) – 125°F (52°C).
3. Vapor recovery applications for flammable liquid dispensing devices. They are intended to operate under a vacuum at the inlet and a maximum discharge pressure of 50 psig (345 kPa), or marked discharge pressure, whichever is less.

1.2  Products covered by this Standard are intended to be installed and used in accordance with the applicable Codes and Regulations as determined by the Authority Having Jurisdiction (AHJ), such as, but not limited to:

1. In the United States:
   1. Flammable and Combustible Liquids Code, NFPA 30;
   2. Code for Motor Fuel Dispensing Facilities and Garages, NFPA 30A;
   3. Liquefied Petroleum Gas Code, NFPA 58; and or
   4. Safety Requirements for the Storage and Handling of Anhydrous Ammonia, ANSI/CGA G-2.1 (ANSI K61.1)
2. In Canada:

1. 1. The National Fire Code of Canada; and or
   2. Provincial or other Regulations.

1.3  These requirements do not cover:

1. Oil burner pumps, which are evaluated in accordance with:
   1. In the United States
      1. The requirements defined in the Standard for Pumps for Oil-Burning Appliances, UL 343.
   2. In Canada:
      1. The requirements defined in the Guide for the Investigation of Pumps for Oil-Burning Appliances, ULC/ORD-C343.
2. Pumps for engine-powered automotive equipment.
3. Pumps for marine use which are evaluated under the Standard for Mechanically and Electrically Operated Fuel Pumps for Marine Use, UL 1130.
4. Pumps for use in chemical, petrochemical, or petroleum processing plants; utility power plants; petroleum production facilities; pipeline pump stations; pipeline or marine terminals; or bulk plant distribution and related facilities.
5. Pumps used in mobile applications, such as on tank trucks, portable tanks, or portable containers mounted on vehicles.
6. Pumps rated more than 600 volts.
7. Pump assemblies also provided with a flammable liquid meter or electrically-operated shutoff valve, which are evaluated in accordance with:
   1. In the United States
      1. The requirements defined in the Standard for Power-Operated Dispensing Devices for Petroleum Products, UL 87.
   2. In Canada:
      1. The requirements defined in the Standard for Power-Operated Dispensing Devices for Flammable Liquids, CSA B346.

1.4  The pump assembly is not prohibited from being constructed such that it provides for the installation and use of a flammable liquid hose and hose nozzle valve.

1.5  "Petroleum Products," as used herein, means gasoline, gasoline/alcohol blends up to 15% Ethanol or 15% Methanol, diesel fuel, fuel oil, lubricating oil, and the vapors of these fuels. Other petroleum products are not prohibited from being used in the pump when the materials comply with the requirements in Materials, Section 5, when the pump is evaluated using the additional liquids, and the additional petroleum products are marked on the pump as indicated in 74.1(f).

1.6 For Power-Operated Pumps to be used with gasoline/ethanol blends with nominal ethanol concentrations above 10 %, refer to the Standard for Power-Operated Pumps for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 - E85), UL/ULC 79A, for additional requirements.

1.7  For Power-Operated Pumps to be used with biodiesel fuel, diesel/biodiesel blends with nominal biodiesel concentrations up to 20 % (B20), refer to the Standard for Power-Operated Pumps for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, UL/ULC 79B for additional requirements.
