The SE2 suction device is a single-line, direct-acting device. It is designed to remove used grease from a bearing and transfer it to a separate container, such as the AFB 10 used grease container.

During the pressurization phase, the connected P 603S single-line pump transfers a preset volume of used grease from the bearing through a separate discharge channel into the AFB 10 container. When the P 603S single-line pump is purged, the vacuum created on the suction side draws the used grease into a measuring chamber. This chamber is emptied during the next pressurization phase. Several suction units can be connected in series. The final unit is equipped with a corresponding elbow fitting.

Its compact size allows the device to be used with small bearings. By agreement with the bearing manufacturer, it can be retrofitted to existing systems.
