Corrosion Resistant Sodium Hypochlorite Dosing System Metering Diaphragm Pump
DFD characteristics of electromagnetic diaphragm metering pumps :
1. Corrosion plastic housing ( ABS + polycarbonate ) ;
2. IP65 degree of protection ;
3. The corrosion resistant pump head : PP, PVC, PTFE, SS 316;
The corrosion resistant Diaphragm : Full PTFE diaphragm, a special process structure, never corrupted ;
5. The double ball way valve : sealing effect doubled ;
6. Eye-catching visual user interface : LED digital display of the current metering pump operating frequency or frequency division multiplication factor, five operating buttons ( START / STOP , ∨ , ∧ , A / M , ADJ ) . START / STOP to start and stop the metering pump , ∧ to increase the flow of metering pumps , ∨ for reducing the flow rate of the metering pump . A / M to switch the metering pump works , ADJ for setting various control parameters . Flow 0-100% adjustable , intelligent digital design, analog circuit abandons adjustment potentiometer and linear drift error caused by bad , avoid traffic caused due to loss of lock when adjusting stroke lead to instability phenomenon , making metering pump flow more accurate , higher repeatability ;
7.A wider range of power supply design :180-250VAC 50-60HZ
8.Powerful control functions: metering pump has two operating modes 1) power protection mode: in this case, the metering pump automatically after power is stopped, to prevent the conditions are not met due to other devices automatically start pump dosing damage to to equipment or personal; 2) power storage : in this case , the metering pump automatically into the state before the power failure after power . The original is running , metering pump continues
