Operation
6.1 Safety instructions for operation
The operating company must ensure that the pump or pump unit is only used within
the parameters and work instructions permitted in the order-related data sheets and in
the operator's manual. Exceeding the limit values or ignoring operating errors can lead
to personal injury, environmental damage and material damage.
Danger of explosion due to inadmissible operating conditions!
During operation, closing the suction line and/or excessive throttling of
the discharge line can lead to an undefined temperature rise and heat
accumulation inside the pump. In order to achieve a shock-free and
smooth start-up process, all pump types must be started up with the
suction valve fully open when completely filled.
- Vibrations, oscillations and shocks caused by external influences
must be excluded.
- The pump may not be operated in cavitation, with zero delivery or
at inadmissible speeds.
- Foreign objects in the pumping medium must be avoided. If the
operating company cannot ensure that the pump will not be
damaged by impurities and solid materials, a filter must be installed
in front of the pump. This filter must be designed to suit the medium
and operating conditions. If foreign objects are detected during
operation, the pump must be switched off immediately and the
cause of the foreign bodies eliminated.
- Never exceed the permissible operating pressures. The maximum
permissible operating pressures are contained in the order-related
pump documentation.
Monitoring parameters: Operating pressure
- Never start and operate positive displacement pumps and side
channel pumps with gate valves, valves or fittings closed.
- The maximum permissible differential pressure may never be
exceeded for positive displacement pumps and side channel
pumps. The maximum permissible differential pressures are
contained in the order-related order documents.
