D35 is a small volume diaphragm high pressure  pump with modular connector. IIts high pressure model D35H can achieve a positive pressure of 135kPa. It is driven by a long-life brushless motor and have options for 12 volt DC or 24 volt DC power. It has high reliability and rich customization options.  Customers can customize the pump head material and elastomer material, and can also customize the connector type.This model can work in both the positive pressure range and the negative pressure range. When only used as a negative pressure sampling pump, it can also be replaced by the C30 model 

 

 

High Pressure Pump Diaphragm

This model is a high-pressure diaphragm pump. Model D35H can output a positive pressure of 135kPa. And can operate continuously under the highest pressure.

 

Working Status Indicator

Only the knob speed control type and frequency speed control type are equipped with working status indicator lights, which can visually 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 motors which have the advantages of long service life, low interference and high reliability.

 

High Pressue Pump with 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

This series of pumps has Rc1/8 internal thread interface, which 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.

 

Optional pump head and elastomer material

In order to achieve better chemical compatibility, the pump head material and elastomer material can be customized. We provide glass fiber reinforced PA6 pump head and EPDM rubber elastomer by default. At the same time, we can also provide PPS pump head option and FKM elastomer option, as well as the combination of the above 4 materials to achieve more extensive chemical compatibility.

 

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, which 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 is normal 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 a LCD touch screen, and alarm codes will be displayed when different faults occur, and fault handling is more convenient. (The figure below is for illustration only, please refer to Chapter 5 Alarms and Troubleshooting for details.)

 

State Memory Function

When the 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.)
