C30 is a compact low noise and low vibration diaphragm air pump. This model is widely used for air sampling pump and vacuum pump that requires low noise and low vibration.

It is driven by durable BLDC motor and have multiple flow control function options. It’s pneumatic connectors can be configured as customer required to adapt different pipe system.This model works in the negative pressure range.

This model works in the negative pressure range. If you need to work in the positive pressure range or pass through the positive and negative pressures, you can choose the D35 pump vacuum and compressor model with similar dimensions.

 

Working Status Indicator

The knob speed control type and frequency speed control type are equipped with working status indicator lights, which can directly feed back the working status of the pump.  The top configuration type is 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 motor which has the advantages of long service life, low interference and high reliability.

 

Air Sampling Pump

This pump can work continuously for a long time with high reliability, and is especially suitable as an online air sampling pump

 

Protections

This model of air sampling pump quipped with overheating protection, overload protection, power supply under-voltage and over-voltage protection and reverse connection protection function. Those functions can greatest extent prevents accidental damage to the pump. The motor also can be sealed under customer requirements for a harsh installation environment.

 

Options for Pump Diaphragm

The materials of pump diaphragm and check-valve can be customized. It has two material options of EPDM and FKM for different gaseous medium.

 

Modular Pneumatic Connectors

This series of air sampling pumps has Rc1/8 internal thread interface. With this interface, this pump can be installed with stainless steel push-in connectors (6mm and 8mm inner diameter), reinforced nylon hose connector, stainless steel hos connectors and PP hose connectors.

This product is equipped with reinforced nylon hose connectors as standard. The standard reinforced nylon hose connector is recommended to match 4*8 silicone tube and the optional plastic and stainless steel hose connectors are recommended to match with 7*13 silicone hose. The size of the tube can be appropriately changed according to the softness and hardness of the hose.

There are two options of stainless steel push-in connectors for matching with 6*8 or 4*6mm hard tubes. The user can select the corresponding pneumatic connectors when ordering according to the pipeline situation.

Speed Control Function

The flow rate of the pump can be changed by adjusting the motor speed. The top configuration type is equipped with an LCD touch screen and speed control signal interface. Those LCD interface can be used to start and stop and control the motor speed through the LCD touch screen, and also through frequency signals.

Knob speed control type models have an external speed control knob, which can control the speed, start and stop of the pump. Frequency speed control type models can be controlled by user inputting frequency signal. Please refer to Chapter 5 Electrical Connection for specific usage of different speed adjustment methods.

Working Status Indication and Warning

1.The knob speed control type and frequency speed 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

a.When the green light is constantly on, it means the power supply isnormal and the pump is not working;

b.When the green light flashes, it means the pump is working normally;

c.When the indicator light remains red, it means that the power supply voltage is too high or too low. If the voltage is correct and the red light is constantly on, it means the pump is working abnormally;

d.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.

2.The top configuration type is equipped with an LCD touch screen. Alarm codes will be displayed when different faults occur, which makes fault handling more convenient. (The figure below is for illustration only, please refer to Chapter 5 Alarms and Troubleshooting for details.)

State Memory Function

When the air sampling pump is stopped due to abnormal power failure, the pump will continue to run according to the state and speed of the last power-off when the power supply is recovered.

When using the knob or touch switch to start the pump, the pump will continue to run at the speed before the last shutdown. (Note: This function is only valid on the frequency speed control type, knob speed control type and top configuration type.)
