Damage to the device must be prevented during transport (use an appropriate packaging). The ambient conditions must be fulfilled even when the device is transported. See Chapter 9.9 Ambient conditions,  62. 1 Check the device on arrival for damage in transit Devices that are no longer used must be properly disposed of in accordance with the applicable national regulations or returned to the manufacturer or sales office.

Technical data Bearing flushing For the following operating conditions bearing flushing is required for a safe, continuous operation: – Applications with special fluids (non mineral oils) due to limited lubricity and narrow operating temperature range – Operation at critical conditions of temperature and viscosity Case drain pressure The permissible case drain pressure (housing pressure) is dependent on the drive speed (see diagram). Size with mineral oil Flushing is recommended with vertical mounting (drive shaft facing upwards) in order to ensure lubrication of the front bearing and shaft seal. Flushing is carried out via port „U“, located in the front flange area of the pump. The flushing fluid flows through the front bearing and leaves the pump together with the case drain flow.

These recommended flushing

 flows will cause a pressure drop of approx. 30 psi (2 bar) (series 1) and 45 psi (3 bar) (series 3) between the entrance to port„U“ and the pump case (including the pipe fittings). Notes regarding series 30 When using external bearing flushing the throttle screw at port U must be turned in to the end stop. Filtration of the fluid (Axial piston unit) The finer the filtration, the better the achieved cleanliness of the fluid and the longer the life of the axial piston pump. To ensure a reliable functioning of the axial piston unit, a minimum cleanliness class of

Single pump with through drive 

 If no further pumps are factory-mounted the simple type code is sufficient. included in this case are: on all through drives except K/U 99 shaft coupler, mounting screws, seal and if required an adapter flange on K/U 99 with through drive shaft, without shaft coupler, without adapter flange; unit is closed with pressure tight cover. Universal through drive On pump sizes 125...355 all through drives are supplied as universal through drives „U“ . These have the advantage, that they can be adapted later on. Simply by exchanging the adapter flange and the shaft coupler it is possible to convert the through drive option. The conversion sets must be ordered separately, see RE 95581.
