A multiple pump system is disclosed. The multiple pump system may include a fluid tank and a multiple pump vessel connected to the fluid tank. The multiple pump vessel may include at least one first pump and at least one second pump located therein. In addition, the at least one first pump may be configured to dispense a fluid from the fluid tank at a first pressure, and the at least one second pump may be configured to dispense the fluid from the fluid tank at a second pressure. The first pressure may be different from the second pressure, such that the at least one first pump may be configured to dispense liquefied natural gas, and the at least one second pump may be configured to dispense compressed natural gas.

A fuel and lubricant refueling vehicle is described. The vehicle has a centralized control panel for monitoring and operating the fuel and lubricant delivery systems. The control panel is operable from ground level. The vehicle is capable of delivering fuels and/or lubricants at 300 gallons per minute. In addition, the vehicle is capable of storing a variety of different fuels and lubricants for servicing multiple types of equipment and work vehicles. The vehicle also has a power generator that supplies 50 cubic feet per minute of air flow to the motor pump assembly of the fuel and lubricant delivery systems.

An electric oil pump includes a base portion, a pump portion, a power supply, a mechanical switch and a pressure trigger. The base portion has a fluid passage. The pump portion is disposed on the base portion. The power supply is provided with an electric power to the pump portion. The mechanical switch is electrically connected the pump portion and the power supply, and has a pressing member. When the pressing member is not pressed, the mechanical switch is in a conductive state, and when the pressing member is pressed, the mechanical switch is in a non-conductive state. The pressure trigger is located between the mechanical switch and the fluid passage, capable of pressing the pressing member when the pressure in the fluid passage is above an upper threshold and releasing the pressing of the pressing member when the pressure in the fluid passage is below a lower threshold.
