Hydraulic Pump

What is a Hydraulic Pump?

A hydraulic pump is a device that converts mechanical energy, typically from an engine or Power Take-Off (PTO) system, into hydraulic energy by moving hydraulic fluid (such as oil) through a system. The pump generates pressure, which powers various components such as hydraulic cylinders, motors, or valves.
Hydraulic pumps are used across various industries for powering equipment that requires auxiliary power. They are integral to heavy-duty machinery like garbage trucks, fire trucks, cranes, construction equipment, and more.

Think of it as the “heart” of the hydraulic system, pushing the fluid to make things work!

How Does a Hydraulic Pump Work with PTO?

The hydraulic pump works with the PTO system by using power from the PTO, which is typically connected to the transmission of the truck. When the PTO operates, it drives the hydraulic pump, which then begins to pump and send hydraulic fluid to various components of the hydraulic system, such as hydraulic cylinders or motors, to enable them to function as needed. The PTO system allows the hydraulic pump to operate without affecting the primary drive of the truck or machinery.

To make this easier to visualize:

• The engine powers the transmission.
• The transmission powers the PTO
• The PTO powers the hydraulic pump.
• The hydraulic pump sends pressurized fluid to run equipment like cranes or hydraulic lifts.

There are two common ways to mount the hydraulic pump:

• Direct Mounting: The pump is mounted directly onto the PTO, making the setup compact and efficient. This is commonly used in systems where space is a constraint.
• Remote Mounting: The pump is mounted separately, often on the vehicle chassis, and connected to the PTO via a shaft or hydraulic lines. This option provides more flexibility in design and easier access for maintenance.

How Does the CC of the Pump Work?

The CC (Cubic Centimeters) refers to the volume of fluid the pump can move with each turn of the shaft.

• Higher CC = More fluid per revolution = Higher power for demanding tasks.
• Lower CC = Less fluid per revolution = Suitable for lighter-duty systems.

In summary, the CC tells you how powerful the pump is in terms of fluid movement. Choosing the right CC ensures the hydraulic system works efficiently and performs as needed.
