Important notice for the conveyance of media containing solids
There is a risk of sedimentation of solids which can settle in the pipe system while the pump
is stopped. Hereby a lump of solids can be formed which can block the pump when it is
restarted. This may cause damages to the pump.
To avoid any damages we recommend in case of longer downtimes to flush the complete
piping including the pump sufficiently.
Hose pumps are positive displacement pumps which must not convey
against closed fittings (e.g. valves). In case of exceeding the maximum
permissible pressure, the pumps or other parts of the facility can be
damaged. Therefore a protection against pressure exceedance must be
integrated in the pipework on the discharge side (e.g. an overflow valve or
a burst disk).
When using overflow valves or burst disks it must be observed that the
overpressure always will be discharged in a safe direction.
I.e., neither people nor tangible assets may be endangered because of
emissions of the pumping medium.
If flammable liquids or gases may leak, the affected area of emission must
be free of ignition sources!
