What Know Before You Buy A Hydraulic Reservoir Tank
Hydraulic Tanks For Every Application
You may know it as a hydraulic oil tank, hydraulic oil reservoir, hydraulic fluid tank or another variation. Regardless what you call them, these oil tanks are one of the most important hydraulic parts of the system. A little bit of knowledge of what to look for can go a long way to saving you time, frustration and expenses in the long run.
When it comes to building a hydraulic reservoir, tank manufacturers can cut corners in several ways without you knowing it. Spend your money wisely. Before buying hydraulic products for your system, ask these pointed questions:
Do you pressure test each hydraulic fluid tank you build?
Most oil tank manufacturers don’t take the time to pressure test each and every hydraulic oil tank they build. Instead they randomly take a few oil tanks off the line for pressure-testing. There is no way of knowing if the one they ship to you is the one with a pinhole that missed the test. Testing every tank is the only way to ensure quality – no exceptions.
Does your hydraulic oil reservoir include anti-vortex?
Another one of the most important hydraulic parts in the system is anti-vortex. Suction at the pump inlet causes a swirling action like water draining in a sink. This introduces unwanted air into the system. Never presume it comes standard and if it doesn’t have it, don’t buy that model of hydraulic oil tank.
Does your hydraulic oil tanks include diffusers?
Put simply – it must have diffusers. Some oil tank manufacturers may cut corners by eliminating diffusers from the hydraulic fluid tank. Diffusers distribute the heat in the hydraulic oil reservoir tank, separate entrained air from the fluid and help to prevent contaminating particles from reentering the system.

What welding method do you use?
The strength of hydraulic products and their associated hydraulic parts are heavily dependent on proper welding techniques.
Constant vibration of heavy hoses connected to the flanges in hydraulic reservoir tank systems can cause metal fatigue and eventual failure. If you are getting an aluminum reservoir insist that they use TIG welding on their flanges. It is much stronger than MIG welds. You can identify a TIG weld by its “stacked dime” appearance.
