Assembly, mounting and installation
When using long metering lines or in the case of an inflexible pipe work,
a pulsation attenuator (pos. 1) should be installed in the pressure line
(directly behind the pressure valve of the metering pump) in order to avoid
pressure strokes.
The suction pipes must be kept as short as possible.
Long and twisted suction pipes may lead to air buildup in the system.
The max. suction height is 2 m and the max. flow velocity is 0.3 m/s!

1 Overflow valve
2 Injector valve (Metering valve)
3 Pressure control valve
The metering point should not be
positioned below the discharge container
as this arrangement creates a risk of the
discharge container being siphoned
empty.
If such an arrangement cannot be avoided
for configuration-technical reasons,
absolutely an appropriate pressure control
valve is to be inserted.
