If you need to reverse a hydraulic pump, there are some steps that you can follow but bear in mind that reversing the direction of a hydraulic pump can damage it sometimes; thus you should only do it if you are confident that it is safe.
The first thing is to identify the kind of pump that you have and whether or not it can be reversed. If in doubt, consult the manufacturer’s manual or contact them directly.
To make your pump reversible, there are several modifications that must be made. One common change is relocating the suction and discharge ports. You should take off the pump housing and remove the suction and discharge lines. After which you will connect the lines back on and put back everything together.
Before starting up, confirm also the right rotation for your pump. You can use a rotation tester or tachometer to check this. Usually, position of drive shaft determines the direction of rotation.
Once all necessary adjustments have been made and rotation has been verified as being correct, turn on your device to see how well its works. Always monitor its functioning closely so as to identify any malfunctioning caused by amendments done.
As far as tools and equipment go, wrenches, screwdrivers and pliers are basic mechanical tools required. Also there may be need for checking which way a pump rotates using a rotation tester /tachometer as well as following all safety requirements such as wearing protective gear at all times when working on it in well-ventilated space among others.
