* Single-pipe system suction side
We thoroughly recommend the use of a prefilter linked to the pump by twin pipes - this allows for manual or
automatic draining of the installation.
Open the drain cock during burner inhibition and only close when oil flows through the drain cock. The volume of
residual air in the pump will be eliminated through the nozzle.
The pump is not amenable to conversion from a twin pipe to a single pipe configuration.
Maximum lengths (intersection of a line and a column) are indicated in metres and have been calculated with four
elbows, 1 stop valve and 1 check valve. In the event of additional limitation, this length should be reduced by
equivalent values as regards head loss.
Examples:
Twin pipe system suction side:
- Suction height: 1 metre
- Length of pipes between the burner and the tank bottom: 25 metres
Pipes with an internal diameter of 8 mm (6 mm is too small as max. length = 10 metres) should be used.
Single pipe system pressure side:
- Nozzle used: 2 gph
- Distance between tank bottom and burner: 0.5 metre
- Pipe length: 70 metres
Pipes with an internal diameter of 6 mm (4 mm is too small as max. length = 24 metres) should be used.
