position. To guarantee its stability, the pump must be screwed appropriately into the ground. The system’s piping must not put any force on the dosing pump’s connections or val- ves. To avoid backfiring dosing after the process end, an electrical and hydraulically locking device is provided on the dosing pump. -
Page 15: Injection Nozzles
Safety and pressure relief valves protect the dosing pump and the associated accessori- es and lines from overloads. They prevent an impermissibly high increase of pressure on the discharge side of the dosing pump that may be caused for example by the accidental closing of valves whilst the pump is in operation or by a clogged injector. - Page 16 Electrical connection data (variants on request) Pump sizes voltage output electricity MIDIDOS [Watt] E 4...10 400/0 0,50/0,87 50 Hz 440/54 0,46/0,80 60 Hz 400/0 0,4/0,7 60 Hz 0/1-Phase 0,85 50 Hz Connection system for the driving motor • supply of three-phase current Y-Schaltung -Schaltung Y-circuit...
