Overall Descriptions

C50 is a large-flow electric diaphragm pump vacuum, equipped with BLDC motor.  This diaphragm pump can be configured with different pneumatic connectors, different elastomer material like EPDM or FKM. It is driven by 24 volt BLDC, with a compact size and high flow-rate, which is used for long-distance and large-flow gas sampling and vacuuming, and has a long service life.

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 24V DC brush-less motors which have the advantages of long service life, low interference and high reliability. The measured continuous life of the premium version of the product can reach 12,000 hours, and the life of the motor can reach 20,000 hours. Working under the maximum pressure will not affect the life.


Protections for C50 Diaphragm Pump

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 of C50 Mini Pump

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 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 checking working conditions 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. It also support a remote communication, communicate distance can be 500m or longer.
