More Oil, Bigger Lifts
The reservoir is the fuel tank of your hydraulic system. When you're driving large-bore cylinders, long strokes, or several cylinders at once, a standard pump can simply run out of oil mid-stroke. Large-capacity reservoir pumps carry the extra usable oil those jobs demand.
Match Reservoir to Cylinder Volume
Every cylinder needs a specific volume of oil to fully extend. A good rule of thumb: your pump's usable reservoir should exceed the total oil volume of every cylinder you plan to advance at once, with margin to spare. Undersize it and the cylinder stalls short of full stroke.
Choose a Large Reservoir When You Have
- High-tonnage or long-stroke cylinders
- Multiple cylinders running from one pump
- Synchronous lifting or heavy press work
We'll Do the Math
Give us your cylinder model(s) and stroke and we'll calculate the oil volume you need and recommend a reservoir capacity that keeps every lift smooth and complete, no stalls, no re-strokes.
Frequently Asked Questions
The reservoir is the fuel tank of the system. Driving large-bore cylinders, long strokes, or several cylinders at once, a standard pump can simply run out of oil mid-stroke and leave the lift incomplete.
The rule of thumb: usable reservoir volume should exceed the total oil volume of every cylinder you plan to advance at once, with margin to spare. Undersizing here is what causes stalls and re-strokes.
Every cylinder needs a specific volume to fully extend, set by its bore and stroke. Give us your cylinder models and strokes on 832-671-0978 and we will calculate the volume and recommend a capacity.
The lift stalls part way and has to be re-stroked, which is slow at best and unsafe at worst if the load is partly supported. It is a sizing problem, not an operator problem.
Single small cylinder, short stroke, one tool. There is no benefit in carrying oil you never use, and reservoir size adds weight and footprint.
