Functions
Operation
Oil is drawn from the suction inlet (S) through the filter (H) to the gear set, where pressure is increased. The diaphragm (D) in the pressure regulator (T) maintains constant pressure at the value set on adjustment screw (P1). In 2-pipe systems, excess oil is returned to the return outlet (R) and the tank. In 1-pipe systems with a plugged return outlet (R) and screw (A) removed, oil is returned internally to the gear set.
Bleeding
In 2-pipe systems, the pump is self-priming, with bleeding performed via the constriction (O) to the return outlet (R). In 1-pipe systems with a plugged return outlet (R), bleeding must be performed through the nozzle outlet (E) or the pressure gauge port (P).
Warranty
Danfoss cannot provide any warranty for pumps used outside the stated technical data or used with oil containing abrasive particles.
