Notes on Installation on Intake Side

NOTE
Avoid the intake line running empty:
• Install foot valve at end of intake line when the pump is higher than the max. liquid level
in the intake tank.
• The calculated size h (see diagram) must not be greater than the specified pump
suction head divided by the density of the delivered medium.
• Use short intake line and avoid thin-walled hoses.
NOTE
Connect intake line to tank slightly above the base of the tank.
IMPORTANT
Provide suitable means for retaining impurities!
Otherwise they can cause faults in the pump and system!
E.g. install a dirt trap (mesh size 100–400 µm depending on medium and type of metering
pump).
NOTE
Install pump with inlet on intake side for gas-emitting media.
NOTE
Intake via siphon line for high-level tanks without connection facilities at base of tank:
• Install filler facility for siphon line (intake line).
• Observe acceleration pressures due to the longer intake line.
