Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.

Can hydraulic pump can be used as hydraulic motor?

Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.


How do you reduce the rpm of a hydraulic motor?

Reduce the output flow of the pump supplying fluid to the motor


What is included in a hydraulic power pack?

In a normal hydraulic power pack you get a pump and motor to power it, the hoses, hydraulic fluid to fill it with as well as the rams to power whatever it is that you are using to connect to the pump and lines.


What is the difference between a hydrostatic and a hydraulic system?

By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".


Can hydraulic pumps be used as motors?

no. motors POWER hydrolic pumps. hydrolic pumps cannot function at the fast rate needed to generate energy as motors do. Answer 2 There is not necessarily any need for a hydraulic - or any other - motor to function at a fast rate, as you put it. A hydarulic pump may need to only turn at say 1 rpm and at this speed send out enough oil to drive a hydraulic motor. Then main thing to consider is what type of pump are we talking about? A gear type oil pumo my well not work at very low speeds, but a piston type pump will work very slowly if needed.
