Installation / Assembly
When using media with a tendency toward sedimentation, the bottom suction valve or foot
valve of the suction line or lance must be installed above the anticipated sediment layer.
Install the appropriate filters in the suction line, since solid matter sucked in can block the
pump.
Discharge lines in systems with ambient pressure
A pressure retention valve or metering valve should be installed at the end of the
discharge line.
The total of all pressure losses in downstream pipeline components (also pay attention to
Δp as a result of height difference!), check valves and pressure retention valves may not
exceed the permitted dosage counter-pressure (see pump specification on name plate).
Discharge lines in systems with overpressure
The total of system overpressure and pressure loss in all downstream pipeline
components (also pay attention to Δp as a result of height difference!), check valves and
pressure retention valves may not exceed the permitted dosage counter-pressure (see
pump specification on name plate).
Suction line
Install line so it rises steadily from container to pump, keeping line as short as possible.
An improper siphon-like arrangement of lines may lead to pump failure!
