Pressure storage pump, type 330, dual-line extraction with return

The pressure accumulator pump Type 330, as the centrepiece of the entire oil system, is used to convey heating oil to one or more consumer points such as oil stoves. Suitable for battery tank systems or single tanks with a backflow limiter in the suction line.

The unit consists of a housing with a pressure accumulator, motor, pump, and a pressure switch. During conveyance, the pump draws in the heating oil and forces it into the pressure accumulator. The pressure cushion contained within pushes the heating oil to the oil stoves. The pressure switch switches on the motor at a lower working pressure of 1.6 bar and switches it off again upon reaching the upper working pressure of 2.6 bar.
