What are the differences between a hydraulic pump and an electric motor?

Is there a difference between hydraulic pumps and motors?

Yes, although they are constructively similar, they have different characteristics, which concern both their specific function and other details necessary for the functioning of the product.

Pumps and motors have different functions

Both pumps and motors are used to make machinery used in a variety of industries, from tractors to agricultural machinery to industrial machinery. Motors with relief and/or anti-cavitation valves, for example, are useful for cooling fans because they offer dual protection against excess pressure and inertia problems.

But their operation is not identical.

In fact, the first difference between pumps and motors – and also the most important – is the function of the two components:

pumps convert mechanical energy into hydraulic energy;
motors, on the other hand, transform hydraulic energy into mechanical energy.
In order to perform the different functions correctly, the two products need diverse features and solutions.

Pumps and motors have different tolerances

The two types of products have different machining tolerances: motor tolerances are tighter so that motors achieve the efficiency they need to work.
