Notes on pipes and hoses
NOTICE
Non-permitted pressure at the inlet IN / outlet OUT
Risk of malfunctions
►
Determine the pressure to be anticipated at the inlet / outlet with the
prescribed values.
Make sure that the cross-section of the connected hoses/piping is at least as large
as the cross-section of the inlet/outlet port sizes.
In order to keep the pressure loss as low as possible, use as few threaded
connections as possible. Connect all connectors to the FAM without initial stress.
The pressure at the inlet/outlet depends on the height differential between the FAM
fluid surface in the tank port (aspiration height
P
(height)
) and the line losses
(
P
(line)
).
If the FAM is above the fluid surface in the tank, determine the pressure as follows:
P = 1 bar -
P
(height)
-
P
(line)
If the FAM is below the fluid surface in the tank, determine the pressure as follows:
P = 1 bar +
P(height)
-
P
(line)
Determine the pressure loss
P
(height)
as follows:
P
(height)
[bar] = h/10.
h
stands here for the distance between the suction connection on the FAM and the
fluid surface in the tank.
