Intended Use; Type Designation - VERDER PACKO ZL Series Operation & Maintenance Manual

1.5 INTENDED USE

The pump should only be used for pumping the media it was selected for and within the limits
specified in the technical datasheets. Any other application beyond the intended use or conversion
of the pump without written agreement with the manufacturer shall be deemed to be not in
accordance with the intended use.
The pump may only be started up for the first time if it has been ensured that all safety devices
are completely fitted and functional.
If any areas are subject to have the risk of explosion, the relevant explosion-proof designed pumps
should be used.
Intended use also covers compliance with the conditions of operation, servicing and maintenance
specified by the manufacturer.
The pump is only to be put into operation filled with medium to be pumped.
Before starting up ensure that:
- Open the valves on the suction side completely to avoid cavitation and,
- Open the valves on the discharge side completely to avoid exceeding the permitted differential
pressure of the pump
- Discharge-side safety measures should be done (e.g. safety valve) to protect the pump from non-
permitted excess pressure
- Protection against contact for hot, cold and moving parts must not be removed during operation
