Suction lines should be kept as short as possible.
Long and intertwined suction lines can lead to accumulation of air in the
system.
The suction height must be a max. of 2 m and the maximum flow rate is
max. 0.3 m/s!
The suction line must always be installed sloping upwards towards the
metering pump.
A metering monitoring instrument, such as an oval gear motor (pos. 1), or
flow monitor, must be installed into the metering line downstream of the
overflow valve and upstream of a pressure control valve or metering valve.
