FAQs 

1. What is a DPP150 Dispensing Peristaltic Pump used for?

The DPP150 is used for accurate fluid dispensing, liquid transfer, dosing, laboratory automation, bacterial culture applications, ultrafiltration systems, and industrial fluid handling processes.

2. How does a peristaltic pump work?

A peristaltic pump moves liquid through a flexible tube using rotating rollers that compress and release the tubing, creating a smooth and contamination-free flow.

3. What is the flow rate range of the DPP150?

The DPP150 offers a flow range from 0.005 ml/min to 641 ml/min, depending on tubing selection and operating speed.

4. What industries use peristaltic pumps?

Peristaltic pumps are widely used in pharmaceutical, biotechnology, chemical, food processing, environmental testing, agriculture, and research laboratories.

5. Does the DPP150 support automation systems?

Yes. The DPP150 features an RS485 communication interface with MODBUS protocol support, allowing easy integration into automated systems.

6. Can the DPP150 run in reverse direction?

Yes. The pump supports reversible operation for filling, dispensing, and liquid recovery applications.

7. What is the speed range of the DPP150?

The pump operates from 0.1 RPM to 150 RPM with precise speed control.

8. Is the DPP150 suitable for sterile or contamination-sensitive applications?

Yes. Since the liquid only contacts the tubing, the risk of contamination is minimized, making it ideal for sterile and sensitive applications.

9. Does the DPP150 include timer functionality?

Yes. The pump includes timing functions as well as programmable delay start and delay stop operations.

10. What communication protocols are available on the DPP150?

11. What laboratory applications is the DPP150 suitable for?

The pump is suitable for:

• Bacterial and cell culture

• Animal heart perfusion

• Quantitative liquid transfer

• Laboratory dispensing

• TFF ultrafiltration

• Chemical dosing

• Coating and granulation processes

12. What are the advantages of a peristaltic pump over other pump types?

Peristaltic pumps offer contamination-free fluid transfer, low shear stress, self-priming operation, easy maintenance, accurate dosing, and compatibility with sensitive biological samples.

13. Does the DPP150 retain settings after a power failure?

Yes. The pump features power-down memory that automatically restores operational settings after power recovery.

14. What tubing options are available for the DPP150?

The DPP150 supports multiple tubing sizes, allowing users to optimize flow rates for different applications.
