Stock In Warehouse
Condition New With Warranty
The Danfoss BFP 52E sizes 3, 5 and 6 oil pumps are designed for small/medium-sized 2-stage domestic oil burners up to 42 l/h.
From the suction inlet (S) oil is drawn through the filter (H) to the gear set, where the pressure is increased. By means of the diaphragm (D) in the pressure regulator for stage 1 (T1), the pressure is kept constant at the value set on adjustment screw (P1). When voltage is applied to the NC-valve, it opens and releases oil to the nozzle outlet. When voltage is applied to the NO-valve, it closes and puts the pressure regulator (T1) out of function. The pressure now rises to the pressure regulator (T2) value for stage 2 set on adjustment screw (P2).
In 2-pipe systems the excess oil is led back to the return outlet (R) and the tank. In 1-pipe systems with plugged return outlet (R) and screw (A) removed, the oil is returned internally to the gear set (see figure).
