Pressure storage pump type 330 two-branch take-off with return flow

The pressure accumulator pump type 330, as the core of the entire oil system, serves to deliver the heating oil to one or several consumption points such as oil stoves. Suitable for battery tank systems or single tanks with a non-return valve in the suction line.

The unit consists of a housing with pressure accumulator, motor, pump, and a pressure switch. During operation, the pump draws in the heating oil and presses it into the pressure accumulator. The pressure cushion inside pushes the heating oil to the oil stoves. The motor is switched on by the pressure switch at a lower working pressure of 1.6 bar and switched off again when the upper working pressure of 2.6 bar is reached.
