Forage harvester hydraulic pumps
The hydraulic pump in a forage harvester converts mechanical power into hydraulic energy that’s used to power the system and move the forks up and down. Without a working hydraulic pump, a forage harvester isn’t able to lift and transport loads.
Signs of hydraulic pump failure include increased noise or heat, cylinders operating erratically, the hydraulic motor slowing down, or the hydraulic system failing to start up at all. As soon as a fault is discovered, the malfunctioning pump needs to be replaced. We offer:

Discover our range of forage harvester hydraulic pumps
We offer a complete range of forage harvester 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 forage harvesters.

Frequently asked questions
A hydraulic pump wears out at the end of its lifespan. If the pump has failed early, check for mechanical failure to the input shaft, make sure the system has enough oil and that the oil is filtering correctly, and check the pressure relief settings.
Gear pumps are highly economical, reliable, and durable. However, they are less efficient than vane and piston pumps and use more energy to get the job done.
A piston pump. These provide the most available energy and produce the least amount of heat.
