Forklift Hydraulic Pumps
A forklift hydraulic pump is a critical component of a forklift’s hydraulic system, responsible for generating the hydraulic pressure needed to power various functions, such as lifting, tilting, and steering. It works by converting mechanical energy from the engine or motor into hydraulic energy, pushing hydraulic fluid through the system. This pressurized fluid enables the forklift’s mast and forks to lift heavy loads efficiently and precisely, ensuring smooth operation.

Types of Forklift Hydraulic Pumps
Discover Our Range of Forklift Hydraulic Pumps
We offer a complete range of forklift hydraulic pumps to keep fluid flowing smoothly through the system:
- Gear pumps are a cost-effective solution that’s easy to use and maintain. Our range includes internal and external gear pumps:
External gear pumps have two identical gears that typically turn towards each other. Oil is transported via displacement chambers that form between the gear tooth profiles, internal walls of the housing, and the surfaces of the bearing blocks. The oil flow is fixed per rotation. - Internal gear pumps operate in the same way as external gear pumps, but the two gears are different sizes. The larger gear (rotor) is the internal gear, and the smaller gear (idler) rotates inside the larger gear. The liquid is pushed forward under pressure when the two gears interlock.
Vane pumps offer a low-noise solution, easy maintenance, and a long lifespan. They have a pump chamber with a central rotor inside that’s equipped with several vanes. The vanes push hydraulic fluid through the pump chamber from the pump’s inlet to its outlet. Vane pumps are suitable for both high- and low-pressure applications up to 200 bar (2900 PSI). - Piston pumps are incredibly reliable and deliver impressive performance. They can operate with pressure levels higher than 350 bar (5000 PSI). Piston pumps use mechanical action to force liquid from the reservoir into the pump’s inlet, through the pump, and out into the hydraulic system. Thanks to regulators that vary the flow per rotation of the pump, piston pumps are the most efficient hydraulic pumps for forklifts.

The Role of Hydraulic Pumps in Forklifts
The hydraulic pump plays a vital role in the operation of forklifts, acting as the powerhouse behind their lifting and maneuvering capabilities. It is the component responsible for providing the hydraulic pressure necessary to perform essential tasks like lifting, lowering, tilting, and moving loads. Without the hydraulic pump, the forklift would lack the strength and control required for efficient operation in warehouses, construction sites, and other industrial settings.
When a forklift operator engages the controls to lift or tilt a load, the hydraulic pump springs into action. It draws power from the engine or motor and uses it to pressurize hydraulic fluid, typically oil. This pressurized fluid is then directed through a network of hoses and valves to the hydraulic cylinders, which convert the fluid’s energy into mechanical motion. This motion enables the forklift to lift heavy loads, tilt its forks, and adjust the mast, ensuring precise control and stability.
In addition to lifting, the forklift hydraulic pump also assists in tilting the mast backward or forward, a critical function for safely stacking boxes, loading pallets, or placing items on high shelves. The smooth and efficient operation of the hydraulic gear pump ensures the forklift can handle heavy loads with precision, making it indispensable in logistics and material handling.
Forklift Hydraulic Gear Pump Parts

The pump housing encases and protects the internal components of the hydraulic pump, including the gears. Made from durable materials like cast iron or aluminum, it ensures the pump can withstand high pressures and harsh working conditions.
(2) Gear Set:
The gear set is the heart of the gear pump, consisting of two interlocking gears—one drive gear and one idler gear. These gears rotate to create suction, drawing hydraulic fluid into the pump. As the gears mesh, they force the fluid out under high pressure.
(3) Input Shaft:
The input shaft connects the pump to the forklift’s engine or motor, transferring mechanical energy to the drive gear. This shaft is designed to handle high torque and rotational speed, ensuring smooth and consistent operation.
(4) Seals and Gaskets:

(5) Bearing Assemblies:
Bearings support the rotating gears and shafts, reducing friction and wear during operation. These precision-engineered components help maintain alignment and ensure smooth gear rotation, which is crucial for consistent hydraulic flow.
(6) Inlet and Outlet Ports:
The inlet port allows hydraulic fluid to enter the pump, while the outlet port directs the pressurized fluid to the forklift’s hydraulic system. These ports are carefully designed to ensure optimal flow rates and minimal resistance.
Choosing the Right Hydraulic Pump for Your Forklift
- Load Capacity Requirements: Determine the maximum weight your forklift will need to lift. The hydraulic pump must be capable of generating enough pressure to handle the load efficiently without straining other components, ensuring safe and reliable operation.
