Assuming you have checked the hydraulic fluid and it's OK, you could look into replacing the seals on the compression cylinder, but with jacks as inexpensive as they are these days, it would be easier and maybe even cheaper to replace the jack. I routinely see two-ton jacks on sale at automotive stores for $20-30. just check the rubber seling at bucket's bottom of the ram and plunger they wear of.f

What is the operation of pump in hydraulic jack?

The operation of the pump in a hydraulic jack is to generate pressure. This causes the jack to rise and lift as needed.


What is the objective of hydraulic jack?

To lift heavy objects with ease.


Advantages of hydraulic jacks?

Hydraulic jacks have the advantage of working quickly to raise or lower items like autos. A hydraulic jack is filled with fluid and can lift heavier loads while using less force.


Is there any Relation between stroke of hydraulic jack and its lifting capacity?

No, not really. Force in hydraulics is only dependent on the force applied to the fluid and the surface area of the hydraulics piston and can be calculated by force in fluid*surface area. This means that the bore which is directly related to the surface area of the hydraulic piston helps to determine the lifting capacity of a hydraulic jack, but that the stroke of the hydraulic jack does not. There are a few reasons however why hydraulic jacks that have a higher lifting capacity might have a shorter stroke. First of all, the greater the surface area of the hydraulic used on the lift, the more fluid must be pumped to raise the lift a certain distance, so you would need more fluid to raise the lift a certain distance. Also, when designing such a mechanism the engineers might have considered the horizontal load on the hydraulic's piston, that might bend it more if the stroke were longer.
