INSTRUCTIONS PUMP TYPE SUNTEC A2L 65C - 75C
Suction line tables
The suction line tables consist of theo-
retically calculated values where the
pipe dimensions and oil velocity have
been matched so that tur-bulences will
not occur. Such tur-bulences will result
in increased pressure losses and in
acoustic noise in the pipe system. In
addition to drawn copper piping a pipe
system usually comprises 4 elbows, a
non-return valve, a cut-off valve and
an external oil filter.
The sum of these individual resi-
stances is so insignificant that they
can be disregarded. The tables do not
include any lengths exceeding 100
m as experience shows that longer
lengths are not needed.
The tables apply to a standard fuel
oil of normal commercial quality
accor-ding to current standards. On
commis- sioning with an empty tube
system the oil pump should not be
run without oil for more than 5 min.
(a condition is that the pump is being
lubricated during operation).
The tables state the total suction line
length in metres at a nozzle capacity
of 9,5 Gph. Max. permissible pres-
sure at the suction and pressure side
is 2,0 bar.
