Shaft end pump /SEP

Check the following to ensure safe operation of the shaft end pump:

• Do not start up the gear unit if the pressure switch is not connected.
• It is essential that the gear unit is sufficiently lubricated from the very beginning. Contact SEW‑EURODRIVE if the shaft end pump does not build up pressure within 10 seconds after the gear unit has been started up.
• A minimum speed of ≥ 400 min^-1 is required for proper operation of the shaft end pump. If you use variable input speeds e.g. inverter-controlled drives or if you intend to change the input speed of a gear unit equipped with a shaft end pump, it is essential that you contact SEW-EURODRIVE.
• An oil heater is mandatory when operating gear units with shaft end pump at low ambient temperatures. For further information, refer to chapter .
