4. Description of function 4.1 Drive The pump unit DLS-Pump 2071 is driven by a direct current gear motor 5 that is flanged to the pump casing 4 from below. 4.2 Delivery function When the eccentric shaft 3 is rotating, the delivery piston 2.1 of every pump element performs a suction and delivery stroke per rotation each whilst delivering lubricant from the reservoir 1 to the lube points.
In some modes of operation, improvement of lubricant quality and delivery behaviour require additional stirring of the lubricant. In the DLS-Pump 2071 pump unit, such stirring is enabled by means of a specially designed eccentric drive. When the eccentric shaft 3 rotates into the one direction of rotation, the pump elements are working whilst the stirrer supplies them with lubricant.
Therefore, in case of an external control, evaluation of the signal available during pump switch-on must be delayed (by approx. 5 s). Lubricant avaible No lubricant avaible (permanent signal) (intermittierendes Signal) Level control „C“ User manual DLS-Pump 2071 Page 16 of 30 Rev.: SG-20220427...
