That looks like it is totally overkill for what you want to do.

first you should probably calculate the pressure and the flow needed for the system.

Flow:

(<Stroke> x (<cross sectional area of the cylinderID> - <cross sectional Area of rod>))/Time

stroke of the cylinder by measuring the cylinder rod at its two extremes and the minus one from the other.

diameter of the rod is easy measured

Internal diameter of the cylinder is harder to measure. check if you can find it written on the cylinder somewhere

then you need to think about how fast you want to go from stop to stop and that is your time

Pressure will be harder and you may need to find a way to put a pressure gauge in one of the lines - alternatively you could measure the force on the cylinder and then calculate the force.

once you have this you can start to specify a pump and directional valve or bi-directional pump. looking at the Raymarine pump, it looks like it is 50bar max - that sound right, i bet it operates much less than that most of the time.
