without bypass to the operating tank

Single-pipe oil supply of oil burners with independently controlling hp feeder units
To DIN/EN 12514 without bypass to the tank

hp-Single and Double pumping units with pressure accumulator control system of series DSK 4.1 and DSk 2.16

Scope of supply:

1 hp-Pump with overflow valve
2 Filter
3 Ball valve
4 Nonreturn valve
5 Membrane pressure accumulator
6 Pressure switch or pressure transmitter
8 Pressure gauge
9 Vacuum gauge
13 Pressure pipe

Two-pipe oil supply of oil burners with hp-Feed pump aggregate to DIN/EN 12514 and DIN 4755, part 2 without overflow valve (item 8) and bypass to tank (item 9)

For single pipe system, there is no overflow valve (item 8) and bypass line to the tank (item 9)
For single pipe system, the electrical control must be designed for intermittent operation. The single pipe pressure is maintained by the adjustable overflow valve integrated into the pump.
