DIMENSION(MM)

Remark

1. The above flow parameters are tested under the conditions of room temperature 23°C, standard atmospheric pressure, clean water, suction lift 0.2m, lift 0, and no pressure. For reference only.

2. Pump flow rate can be affected by viscosity, density, medium temperature, ambient temperature, inlet and outlet pressure, suction lift and lift of pump. To ensure the accuracy of the pump, it is necessary to keep the above factors without significant changes.

• High precision, long lifetime, durable

• Straight tube installation method to avoid residual stains (straight, U-shaped, L-shaped are available)

• Waterproof pump head prevents water from entering the motor

• Whole detachable pump head , convenient for tube replacement and maintenance

• Low noise, smooth operation, fine-tunable pressure tube to avoid dripping

A range of tube materials is available to handle a range of different chemicals as well as hygienic options for food and beverage dispensing.

1. What is a peristaltic pump?

A peristaltic pump is a type of positive displacement pump that transfers liquids through flexible tubing. The liquid only contacts the tube, making the pump suitable for applications requiring clean, contamination-free liquid transfer.

2. What liquids can the LFP501DB.G peristaltic pump transfer?

The LFP501DB.G is suitable for low‑to‑medium viscosity liquids such as water, nutrient solutions, detergents, inks, beverages, and mild chemical solutions. For aggressive or volatile fluids, compatible tubing materials (BPT, silicone, A60‑F, Viton) should be selected based on chemical compatibility.

3. Does the liquid come into contact with the pump mechanism?

No. In a peristaltic pump, the liquid flows only through the tubing and does not contact internal pump components. This design helps reduce contamination and simplifies maintenance.

4. Can the LFP501DB.G peristaltic pump run dry?

Yes, the pump can tolerate short periods of dry running because the liquid is contained within the tube. However, prolonged dry operation may accelerate tubing wear and reduce its service life, so it is not recommended for extended use.

5. How often should the tubing be replaced?

Tubing replacement intervals depend on factors such as operating hours, fluid type, pressure, and tubing material. Regular visual inspection is advised – replace the tube when signs of fatigue, cracking, or permanent deformation appear to maintain consistent flow accuracy.

6. Is the LFP501DB.G suitable for continuous operation?

Yes. The LFP501DB.G DC peristaltic pump is designed for repeated and continuous liquid transfer applications. Actual service life depends on operating conditions and system design.

7. What makes the LFP501DB.G different from standard peristaltic pumps?

Key differentiators include:

• High precision – delivers stable, repeatable flow rates.

• Waterproof pump head – prevents moisture ingress to the motor.

• Fully detachable pump head – allows quick tube replacement and easy maintenance.

• Adjustable pressure tube – enables fine‑tuning to avoid dripping.

Multiple tube installation options (straight, U‑shaped, L‑shaped) to reduce residual stains.

8. What is the flow rate range of the LFP501DB.G?

The LFP501DB.G provides flow rates from 950 ml/min to 2600 ml/min, depending on the tubing size (26#, 35#, or 36#) and the selected tubing material. It operates at a fixed flow rate per tube configuration with DC24V input.

9. What applications is the LFP501DB.G commonly used for?

This pump is ideal for applications requiring precise, repeatable liquid dosing, such as laboratory dispensing, medical device integration, beverage portioning, industrial ink delivery, hydroponic nutrient feeding, and water treatment systems where contamination‑free transfer is critical.

10. Can the LFP501DB.G be customized?

Yes. LEFOO supports OEM customization, including alternative tubing materials, connector types, mounting hole configurations, and specific voltage or flow adjustments. Please contact our technical team to discuss your project requirements.

11. What are the operating conditions for the LFP501DB.G?

The pump operates reliably at ambient temperatures of 0–45°C and relative humidity below 85%RH (non‑condensing). It is powered by DC24V with maximum power consumption of 24W and weighs approximately 825g.
