Cat 3116 fuel pump

Types of CAT 3116 fuel pumps

The Caterpillar 3116 fuel pump is a positive displacement rotary pump that supplies fuel from the gas tank to the engine. It is an electric pump that is located underneath the gas tank and inside the gas tank. The 3116 fuel pump has two main types:

• CAT 3116 inline fuel pump: In this configuration, the pump is placed in the fuel line between the fuel tank and the fuel injection system. It is responsible for maintaining fuel pressure and flow rate, ensuring that fuel is delivered consistently to the injectors, regardless of engine speed or load. An inline fuel pump is typically used in fuel systems with direct fuel injection. The CAT 3116 inline fuel pump has the following advantages:
• 1. Reliable fuel delivery: The inline fuel pump provides a constant and reliable fuel supply to the engine, ensuring optimal performance and efficiency.
• 2. Easy installation: It is easy to install and integrate into existing fuel systems.
• 3. Cost-effective solution: Inline fuel pumps are often more affordable than other fuel delivery system options.
• 4. High-pressure fuel delivery: The pump can generate high pressure, which ensures a consistent and precise fuel supply to the engine, optimizing performance.
• 5. Compact design: Inline fuel pumps are often compact and lightweight, making them suitable for various applications where space is limited.
• CAT 3116 rotary fuel pump: A rotary fuel pump is a positive displacement pump that uses rotating lobes to move fuel through the pumping chamber. The pumping chamber is designed with an eccentric bore fitted with rotating lobes. As the lobes rotate, they slide past each other, creating a change in volume in the pumping chamber. This action draws fuel into the chamber during the lobes' rotation and pushes it out of the chamber, generating flow. The pumping chamber features inlet and outlet ports that allow fuel to enter and exit the chamber. As fuel enters the pumping chamber through the inlet port, the rotating lobes create a vacuum that draws fuel in. The movement of the lobes pushes fuel out of the chamber through the outlet port, delivering a continuous flow of fuel. The CAT 3116 rotary fuel pump is typically used in high-performance engines where precise fuel delivery is critical for optimal combustion and power generation.

Specifications and Maintenance of Cat 3116 Fuel Pump
