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 !
