Hydraulic tanks and accessories

We source our hydraulic tanks, along with their brackets and accessories, from our Italian supplier. These tanks can be mounted on the side of the chassis, behind the cab, or within the chassis itself. We offer tanks made from aluminum, stainless steel, or painted carbon steel.

Hydraulic tanks are quite similar to fuel tanks.

Their manufacturing technology is similar, but due to their size, baffle plates are rarely installed. This is usually unnecessary because hydraulic tanks are typically full while in use. It is also possible to design combined tanks for storing both fuel and hydraulic fluid. A digital level indicator, which displays on the dashboard, is an important feature of fuel tanks. For hydraulic tanks, we use a visual level indicator that can be combined with a temperature gauge, which provides useful information during hydraulic operations.

Hydraulic tanks can be made from steel, aluminum, or stainless steel. When choosing the material, it is essential to consider corrosion resistance. For aluminum tanks, strict adherence to manufacturing technology is crucial to ensure proper quality, as welding aluminum is more challenging than welding steel. As a result, a seemingly cheaper aluminum tank could become much more expensive in the long run due to potential cracks, compared to an initially more expensive option.

The brackets for hydraulic tanks are narrower than those for fuel tanks due to limited available space, which unfortunately also means they have a shorter lifespan. Therefore, during maintenance, extra attention should be given to these brackets.

When selecting the tank size, you should consider whether it will serve hydraulic cylinders or continuously operating hydraulic motors. In the case of cylinders, the tank capacity should be safely larger than the combined volume of the cylinders and hoses. For hydraulic motors, cooling considerations are most important. If the system does not have a hydraulic cooler, the tank size (in liters) should be at least 1.5 times the motors' per-minute consumption in liters!

Tanks come in various cross-sectional sizes, which affects the space they occupy on the side of or within the chassis. Large tanks can be placed behind the cab, but this requires the appropriate design of the superstructure. If the tank is built into the chassis, checking the oil level can be more challenging. With a dump truck, special care must be taken to securely block the raised platform during maintenance to prevent it from falling on the technician! Meiller often installs hydraulic tanks within the chassis.

When placing the tank, consider the type of hydraulic pump! Swash plate axial piston pumps, although capable of creating high pressure, do not "like" to suck – despite what their name suggests. Therefore, with these pumps, it is advisable to design the lowest oil level point slightly above the pump level. The best suction capability belongs to the bent axis piston pump.

The suction hose between the pump and the tank must be vacuum-resistant to prevent it from collapsing due to suction.

We always recommend installing a return line filter in the system, even if there is a pressure line filter. The place for this is pre-prepared on the top of the tank. Return line filters come in various types, so it is advisable to consult with the experts at MPH Kft. to avoid annoying oil leaks in the future. However, the drain oil should always be returned directly! MPH Kft. ensures that the hydraulic tanks they sell are equipped with a drain oil return fitting.
