D50 is an electric diaphragm micro air pump driven by a brushless motor. It can be used to pump negative pressure or positive pressure. It has a variety of flow adjustment functions and can be controlled by electronic signals or touch LCD screens.This diaphragm pump can be configured with different pneumatic connectors, different elastomer material like EPDM or FKM.Those micro diaphragm pumps can be configured with different pneumatic connectors and materials of elastomer.

Micro Air Pump for Vacuum and Pressure

It can be used to pump negative pressure or positive pressure. Max vacuum rate of D50 is -62kPa and max pressure is 120kPa. It can work under maximum pressure continously. The maximum average flow rate is 15L.min. If you are looking for a air pump with high flow rate, please refer to D60 Diaphragm Pump & Compressor

 

Working Status Indicator

Only the remote control type and basic type are equipped with working status indicator lights, which can visually feed back the working status of the pump. The touch control type and top configuration type are equipped with an LCD touch screen that can display working status and fault codes.

Brush-less DC Motors

This model is driven by brush-less motors which have the advantages of long service life, low interference and high reliability.

Protections

Equipped with overheating protection, overload protection, power supply under-voltage and over-voltage protection and reverse connection protection function, which to the greatest extent prevents accidental damage to the pump.

Modular Pneumatic Connectors

The design of this series of pumps adopts modular connectors,using non-detachable reinforced nylon hose connectors as standard accessory.Customers can also choose Rc1/8 internal thread interface (materials can be reinforced nylon or stainless steel). This interface can be used with PC6 or PC8 stainless steel quick-change connectors, plastic (PP) hose connector, and stainless steel hose connectors.

The standard non-detachable reinforced nylon hose connectors and stainless steel hose connectors are recommended to be used with 7*13mm hoses. There are two options for quick-change connectors, matching hard tubes with outer diameters of 6mm and 8mm; plastic hose connectors are recommended to match 6*10mm hoses; customers can choose corresponding pneumatic connectors when ordering according to the specific pipeline situation.

Speed Control Function

Only the touch control type and top configuration type are equipped with an LCD touch screen, which can control the start-stop and speed of the pump through the LCD touch screen. Flow rate can be easily adjusted through the speed control function. In addition, the top configuration type is also equipped with remote frequency speed control and remote voltage speed control functions.

State Memory Function

When the micro air pump is stopped due to abnormal power failure, it will continue to run according to the state and speed of the last power-off when the power supply is recovered. When the pump can work normally, touch the screen to start the pump, it will continue to run at the speed before the last shutdown. (Note: This function is only valid on the touch control type and top configuration type.)

RS-485 Communication Function（Top Configuration Type Only）

With RS-485 serial port communication function, the running status of the pump can be monitored in real time through the serial port, which is convenient for working conditions check and fault history query and control.

The Modbus communication protocol based on RS-485 can be customized for top configuration type products, through which users can monitor the pump speed, start-stop control and working status.

Speed Control Function

The flow rate of the pump can be changed by adjusting the motor speed. The touch control type and top configuration type are equipped with an LCD touch screen. This type can realize the start-stop control and motor speed control. In addition, the top configuration type also supports remote frequency speed control and remote voltage speed control. Through the wiring of the speed control connector, remote start-stop and speed control of the pump can be realized.

Working Status Indication and Warning

1.The basic type and remote control type are equipped with working status indicator lights. Users can understand the working status of the equipment through the color change of the indicator lights:

1. When the green light is constantly on, it means that the power supply isnormal and the pump is not working;
2. When the green light flashes, it means the pump is working normally;
3. When the red light is constantly on, it means the pump is working abnormally;
4. When the positive and negative poles are reversed, the indicator light is off, the pump does not work, but it will not damage the pump.
