Installation example 6
The suction line must always be installed sloping upwards towards the
metering pump.
Installation example 7
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.
6.3.3 Connection of the suction and pressure lines (dosing lines)
CAUTION!
Ensure that the required seal is achieved when connecting the suction and
pressure lines by fitting
O-rings on the connections.
The use of a suction pipe with an empty signal provision and dirt trap from our
accessory programme is highly recommended to protect the metering system.
The empty signal system causes the pump to cut off if the medium in the
container drops below a certain level.
