Features of DFD electromagnetic diaphragm metering pump :
- Anti-corrosion plastic shell ( ABS+ polycarbon);
- IP65 protection grade;
- Corrosion-resistant pump head: PP , PVC , PTFE , SS 316 ;
- Corrosion-resistant diaphragm: full PTFE diaphragm , special process structure, never damaged;
- Double ball check valve: double the sealing effect;
- Intuitive and eye-catching operation interface: LED digital tube displays the current working frequency or frequency division and multiplication factor of the metering pump, and 5 operation buttons ( START/STOP , ∨, ∧, A/M, ADJ). START/STOP is used to start and stop the metering pump, ∧ is used to increase the flow of the metering pump, and ∨ is used to reduce the flow of the metering pump. A/M is used to switch the working mode of the metering pump, and ADJ is used to set various control parameters. The flow rate is adjustable from 0-100%, and the intelligent digital design eliminates the drift caused by the adjustment of the analog circuit potentiometer and the error caused by the poor line shape, and avoids the unstable flow caused by the loss of lock when adjusting the stroke. phenomenon, making the flow rate of the metering pump more accurate and the repeatability higher;
- Wider range of power supply design: 180-250VAC 50-60HZ is more suitable for China's national conditions;
- Powerful control function: The metering pump has two working modes 1) Power-off protection mode: In this case, the metering pump will automatically enter the stop state after being powered on again to prevent the pump from automatically starting and adding medicine due to the lack of other equipment conditions. Injury to equipment or personnel; 2) Power-off storage method: In this case, the metering pump will automatically enter the state before power-off after power-on again. When it was originally running, the metering pump continued to run, but when it was stopped, the metering pump continued to be in a stopped state;
- Additional liquid level or remote control function: the metering pump is equipped with a liquid level or remote control interface, and the status of the liquid level or remote control signal is optional: closed or disconnected. This allows the metering pump to be connected to any type of level switch or remote control signal.
