5.4 Switching - on
Check before switching on:
Make sure that pump with drive unit has correct mounted and connected.
Are they Circuit points leak-proof and zero-potential connected?
Shaft seal okay?
Did you have installed necessary safety devices?
If necessary locking pressure systems connected?
1. Before starting the pump, check it for contamination and any foreign matter.
2. Fill the pump with your medium for pumping. This filling is used to lubricate rotor and stator,
and to avoid dry running of the pump unit.
3. Open valves full.
4. Switch on drive unit.
5. After first start check at nominal pressure pump and pipe connection are leak proof.
5.5 Operation
Do not operate against closed shut off devices!
Pipe work can burst!
Possible dangerous situation: Severe or fatal injuries!
Secure the pump by means of approved safety devices (overpressure monitoring)!
After the pump has been started, ensure at all times that the suction housing in the pump
is continuously provided with pumping medium.
Use suitable monitoring and shutdown devices to protect the pump against dry running.
Dry-running of the helical rotor pump will damage the stator!
Whenever there is no pumping medium in the intake pipe, the pump must be shut down
immediately!
