What To Know About A Hydraulic Pump Reservoir Tank
And Hydraulic Reservoir Sizing Before You Buy
The hydraulic tank is one of one of the most important components of your hydraulic system.
The hydraulic oil reservoir design you choose can have negative consequences that can cost time, money and frustration if you don’t know what to look for. Take a moment to learn these critical factors about important hydraulic reservoir parts that some manufacturers exclude without you knowing.
If you already have a firm knowledge of hydraulic oil reservoir design, go ahead and browse our catalog to find a hydraulic tank to suit your needs.
Hydraulic Tank Manufacturers Can Cut Corners In Ways That Are Undetectable
The manufacturing cost of a hydraulic pump reservoir tank can be cut significantly when components are omitted and quality control steps are skipped. Worst of all – it may not be until the oil begins to flow that you discover something is very wrong.
Most hydraulic tanks look similar on the outside. It is the hydraulic reservoir parts on the inside that matter most. This is what you need to ask:
Does You Hydraulic Oil Reservoir Design Incorporate Vortex Suppression?
Due to suction from the hydraulic pump reservoir tanks are subject to a vigorous swirling action of the oil similar to water draining in a sink. It’s commonly known as a vortex. That vortex draws unwanted air into the hydraulic oil. That’s a problem you can do without. Don’t assume anti-vortex comes standard with all hydraulic reservoir s. If it isn’t included, don’t buy the tank at any price.
Do Your Hydraulic Pump Reservoir Tanks Include Diffusers?
Some tank manufacturers think they can get away with leaving diffusers out. Each of our hydraulic oil reservoir designs includes diffusers because they deliver three important benefits:
- They help separate entrained air from the fluid
- Cooling is enhanced through improved heat distribution (hydraulic reservoir sizing is also a factor in removing heat)
- They help prevent impurities from reentering the system
Diffusers are one of the most important hydraulic reservoir parts in the tank. They should be included without exception.
Do You Leak Test Every Tank You Build?
We’ve heard horror stories about oil tank manufacturers shipping new tanks that leaked at the weld on the first day of use. One pinhole can do that. Skipping the leak test got their tank built faster and cheaper but at their customer’s expense. We pressure test each and every hydraulic tank before it leaves the factory because we want you as a satisfied, repeat customer.
Hydraulic Reservoir Sizing
When it comes to hydraulic reservoir sizing there is a rule of thumb that is generally accepted. In an open circuit for a conventional reservoir the general rule is a tank capacity of about 3 to 5 times the flow of the pump(s) per minute with the addition of a ten percent air cushion. This is a case where size does matter. If you have the room available – opt for a larger tank.
