EWDOSEProduct advantages of (New Deutz)

I. In terms of stability and precision:

Digital circuit control is more precise and reliable than traditional knob adjustment. Because it eliminates the drift of analog circuit potentiometer regulation and the error caused by poor line alignment, and there will be no situation of flow variation due to the loss of lock of the stroke regulation device. Under the condition that the system pressure remains constant, the repeatability accuracy can reach0.5％.

Ii. Anti-corrosion aspects:

1"All"PTFEThe diaphragm, with a special process, ensures that the diaphragm sheet has both toughness and strength, and does not need to be replaced throughout its lifetime. However, other brands of metering pumps all use composite diaphragms, which are prone to cracking or tearing, causing great inconvenience to your production and maintenance.

2The flow-through part of the pump head has no metal components, which makes it superior in terms of corrosion resistance.

Iii. Leakage Prevention:

1Each check valve is sealed by two balls, enhancing the sealing effect and effectively preventing leakage from the pump head.

2A complete set that never needs to be replaced for lifePTFEThe diaphragm itself is the guarantee to prevent leakage from the pump head.

Iv. Control Aspect:

1Panel display makes flow adjustment more intuitive and accurate! The adjusted flow rate is the flow rate displayed on the panel and does not require shutdown for calibration.

2Can meet the requirements of pulse signals or4-20mAReception of analog signals, built-in pulse frequency dividerA/DThe converter, thus saving the cost of your external signal converter.

3As the control part adopts digital circuit control, its system parameters can be set according to your actual needs.

V. Other Aspects:

1The independently developed metal-coated plastic heat dissipation structure makes the circuit board have a longer lifespan.

2The program can be modified according to the user's process, and it is very easy to add interfaces and change algorithms.

3The overall performance ratio of the machine is better, and the accessories are cheaper and faster.

DFDFeatures of the series of electromagnetic diaphragm metering pumps(Manual control, with an external liquid level switch available):

1. Anti-corrosion plastic casingIP65Protection grade

2. Corrosion-resistant pump head: Material of the pump headPP,PVC,PTFE,SS316Such as

3. Corrosion-resistant diaphragm: AllPTFEThe diaphragm, with a special process, ensures that the diaphragm sheet has both toughness and strength, and does not need to be replaced throughout its lifetime.

4. Double ball check valve: Each check valve is sealed by two balls, enhancing the sealing effect and effectively preventing leakage from the pump head

5. Intuitive and eye-catching operation interfaceLEDThe digital tube displays the current working frequency of the metering pump. The start, stop and flow rate adjustment only require three buttons. "Traffic"0-100％Adjustable, intelligent digital design, it eliminates the drift of analog circuit potentiometer adjustment and the error caused by poor line type, and there will be no situation of flow change caused by the loss of lock of the stroke adjustment device, making the flow of the metering pump more accurate and the repeatability higher.

6. Wide-range power supply design180-250VAC 50-60HZ A more suitable national condition

7. Enhanced control function: The metering pump has two working modes1Power-off protection mode: In this case, the metering pump will automatically enter a stop state after being powered on again to prevent damage to the equipment or personnel caused by the automatic start of the pump to add chemicals due to the lack of other equipment conditions.2Power-off storage mode: In this case, the metering pump automatically enters the state before power-off after being powered on again, saving the time you would spend recalibrating

8. Convenient liquid level or remote control function: The metering pump is equipped with a liquid level or remote control interface. The state of the liquid level or remote control signal can be selected as: closed or open. This enables the metering pump to be connected to any type of liquid level switch or remote control signal.
