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 LFP501ST peristaltic pump transfer?

The LFP501ST peristaltic pump is suitable for transferring various low‑viscosity liquids, including water, nutrient solutions, detergents, cleaning liquids, inks, beverages, and other compatible fluids. Tubing material should be selected according to the liquid properties.

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 LFP501ST peristaltic pump run dry?

Peristaltic pumps can generally tolerate short periods of dry running because the liquid is contained inside the tubing. However, extended dry operation may reduce tubing life and is not recommended.

5. How often should the tubing be replaced?

Tubing replacement intervals depend on operating conditions, running time, liquid type, pressure, and tubing material. Regular inspection is recommended to maintain optimal pump performance.

6. Is the LFP501ST suitable for continuous operation?

Yes. The LFP501ST stepper motor peristaltic pump is designed for repeated and continuous liquid transfer applications. Actual service life depends on operating conditions and system design.

7. Can the pump be customized?

Yes. LEFOO supports OEM and customization services, including voltage options, tubing materials, connectors, mounting configurations, and application‑specific requirements.

8. What is the flow rate range of the LFP501ST peristaltic pump?

The LFP501ST provides a wide adjustable flow range from 10 ml/min to 1600 ml/min at DC24V, depending on tubing size (24#, 35#, or 36#) and motor speed settings. The stepper motor enables precise, digitally adjustable flow control.

9. What applications is the LFP501ST commonly used for?

Thanks to its high precision, stepper motor drive, and PLC/485 communication capability, the LFP501ST is ideal for applications requiring accurate, adjustable dosing and remote control, such as laboratory analysis, pharmaceutical metering, chemical injection, hydroponic nutrient dosing, food additive dispensing, industrial automation, and water treatment systems where flow rate needs to be dynamically regulated.

10. What are the advantages of the LFP501ST stepper motor peristaltic pump?

The LFP501ST combines high precision, durable construction, and flexible control. Its stepper motor allows for precise, adjustable flow rates, while optional driver and PLC control with 485 communication enable seamless integration into automated systems. Additional benefits include a waterproof pump head, fully detachable pump head for easy tube replacement, low‑noise operation, and multiple tube installation options (straight, U‑shaped, L‑shaped) to minimize residual stains. It is an excellent choice for OEM equipment requiring accurate and remotely controllable fluid handling.
