Caution
Risk of damage to the system! We always recommend using pulsation dampers for
large high-speed pumps!
Since the pulsation is influenced by many factors, a system-specific calculation is
essential, e.g. on request with our calculation program.
To install the suction line:
• Keep the suction line as short as pos-
sible, avoid a tangled suction line
• If necessary, use swept bends
instead of elbows.
• Always lay the suction line rising to
the suction valve of the dosing pump.
• Avoid loops which cause air bubbles.
For easy deaeration of the dosing head:
Install a ball valve (11i) with bypass line (back to the dosing tank)
immediately behind the pressure valve.
In case of long pressure lines:
• Install a check-back valve (12i) into the dosing line.
For suction-side installation
• Depending on the pump type and line length, it
may be necessary to use a suction pulsation
damper (4i).
Observe the “Approximate values when using
pulsation dampers” auf Seite 22 and if necessary
request a system-specific calculation from our
calculation program.
For pressure-side installation
• Depending on the pump type and line length, it may be
necessary to use a pulsation damper (4i) on the
pressure side.
For rigid pipework and line length > 2m, for flexible
pipework and line length > 3m, depending on the
pump type and size, use pulsation dampers (8) to pro-
tect the system.
