The OH3 pumps are installed in places where the customer did not have enough space to install an OH2 pump. For these type of topics we normally advise the OH5 pump, however in case customer prefers separate bearing housing we can also continue with the OH3. The flexibility is that we do not have to make other performance curves as our hydraulics are identical for the OH2, OH3, OH5 and VS4. Meaning we can share a performance curve and customer is still able decided on orientation (horizontal or vertical) and execution (bearing house or close coupled motor).
