Timered/constantdosingpump.
Settingtheswitchontheconstant position,thepumphasflowcontrol(frontpanelknobmaybeset
from0%to100%ofpumpnominalcapacity).Flowcontroliselectronicallysetanditoperatesonpump
injectionsnumber.Toavoidlinearityproblemdonotsettheknobofpumpflowbetween0%and10%.
Settingtheswitchontimered ,thepumpstartsworkingwhenanexternalpulseisprovided.Working
activetimeforeachexternalpulseissetontheadjustmentknobintherangebetween0and60seconds
(differenttimeareavailableupondemand).
Thecapacitycanbealsochangedadjustingthestrokeperminute,operatingthe%markedknob,at
thesametime.
Thedoubleparameteradjustment (strokes and time) allowstheuse of this pump inhighcapacity
systems,wherethepulsesarenotenoughtodriveaPVtypepump.
TEpumpisprovidedofacoaxialcable(RG58)withBNCplugtoconnectthecommandsignal.
