Bearing flushing

With the following operating conditions, bearing flushing is necessary for safe continuous operation:

  • Applications with special fluids (not mineral fluids) due to limited lubricity and tight operating temperature range
  • Operation with boundary conditions of temperature and viscosity with mineral oil operation

With vertical installation (drive shaft upwards), bearing flushing is recommended for lubrication of the front bearing and the shaft seal ring.

The bearing is flushed using port "U" in the area of the front flange of the variable displacement pump. The flushing fluid flows through the front bearing and exits with the pump leakage at the leakage connection.

Recommended flushing quantity

Size

4071125180250355

Recommended flushing quantity

l/min

34571015

The specified flushing quantities result in a pressure differential between port "U” (including fitting) and the leakage chamber of approx. 2 bar (series 1) and approx. 3 bar (series 3).

When using the external bearing flushing, the throttle screw in port U has to be screwed-in to the stop.

Leakage pressure

The admissible leakage pressure (housing pressure) depends on the speed (see diagram).

Maximum leakage pressure (housing pressure): 4 bar absolute

These specifications are guidelines; under special operating conditions, a limitation may become necessary.

Notes on external supply:

  • In the case of an actuating system with external supply, the pump adjustment will - in case of voltage failure - not switch to zero stroke but to the negative stop (displacement of 100 % flow from the system to the tank).
  • With an active fault message, it is imperative that the machine control reacts (e. g. switching off the drive motor of the pump, interrupting the external supply of the actuating system).
  • The command values for pressure and flow must always be greater than zero (pcommand ≥ 3 bar, αcommand ≥ 5 %) as due to drift or tolerances, there is no exact "zero" pressure or "zero" swivel angle. Under unfavorable conditions, smaller command value presettings can lead to cavitation.
  • The actual pressure value must not be less than 10 bar for more than 10 minutes (lubrication).
  • Port Z must be connected to tank level in case of non-use. Closing is not admissible.

Project planning information

  • Command values may only be switched via relays with gold-plated contacts (low voltage, low currents)
  • Always shield command and actual value cables.
  • The distance to aerial lines or radios must be at least 1 m.
  • Do not lay signal lines close to power lines.
  • Amending notes on the SYHDFE control system can be found in the operating instructions (See section “Further information about this control system”).

Through-drives : Size 40 … 71

The control systems of size 40 … 71 are partly supplied with through-drive "K99".

Their advantage is that the through-drive can be subsequently modified. By simply exchanging the intermediate flange and the hub, the through-drive can be adjusted to the on-site requirements.

The assemblies as exchange kits can be ordered separately, see "Accessories for through-drives" as well as data sheet 95581.

Small centering diameters are directly worked into the pump subplate. Subsequent modification is not possible. In this connection, observe the "Type codes" as well as "Accessories for through-drives". Hubs for through-drives can be ordered separately.

Through-drives : Size 125 … 355

The control systems of size 125 … 355 are supplied with universal through-drives "U99".

Their advantage is that the through-drive can be subsequently modified. By simply exchanging the intermediate flange and the hub, the through-drive can be adjusted to the on-site requirements.

The assemblies as exchange kits can be ordered separately, see "Accessories for through-drives" as well as data sheet 95581.

Mounting

Tightening torques

  • The tightening torques specified in this data sheet are maximum values and must not be exceeded (maximum values for screw-in threads). Manufacturer's specifications regarding the maximum admissible tightening torques of the fittings used are to be
  • For mounting screws according to DIN 13, we recommend checking the tightening torque case by case accordingto VDI 2230, version 2003.

Accessories

Through-drives

The following conditions apply to the attachment pumps listed in the table:

  • Internal gear pump PGH with shaft "R", flange "U2", see data sheet 1022
  • Internal gear pump PGF3 with shaft "J", flange "U2", see data sheet 10213
  • External gear pump AZPF with shaft "R", front cover "R", see data sheet 10089

Observe that the through-drive of the main pump and the flange of the attachment pump (see type key pump) are identical. Check in the current data sheet of the gear pump whether the shaft ends have the specified dimensions.
