Lefoo LEFOO Rotary Diaphragm Pump

Name: LEFOO Rotary Diaphragm Pump
Brand: LEFOO INDUSTRIAL CO.,LTD.
Rating: 4.8 (50 reviews)

LEFOO Rotary Diaphragm Pumps are high-flow, low-pulsation liquid transfer pumps designed for OEM equipment requiring stable and repeatable fluid delivery. Unlike conventional peristaltic pumps that rely on compressible tubing, the rotary diaphragm design combines smooth liquid output, low vibration, and extended service life in a compact pump solution.

With an integrated pulsation damping structure, the LFP4000 Series helps reduce flow fluctuation and provides stable liquid delivery from 1,500 to 4,000 mL/min. The pump is suitable for laboratory equipment, beauty devices, water treatment systems, cleaning and disinfection equipment, beverage dispensing equipment, and other automated liquid handling applications.

Available in 24V DC with flexible connector options, LEFOO Rotary Diaphragm Pumps can be customized to match different tubing layouts and OEM system requirements.

FAQ of LEFOO Rotary Diaphragm Pump

What is a rotary diaphragm pump?

A rotary diaphragm pump is a liquid transfer pump that uses a diaphragm-based pumping structure to move fluid. The LFP4000 Series is designed to provide high flow, low pulsation, and stable liquid delivery for OEM equipment.

What applications is the LFP4000 Rotary Diaphragm Pump suitable for?

It is suitable for laboratory equipment, beauty and aesthetic devices, water treatment equipment, cleaning and disinfection systems, beverage dispensing equipment, and automated liquid transfer applications.

What is the flow rate of the LFP4000 Series?

The reference flow range is 1,500 to 4,000 mL/min at 24V DC. Actual flow depends on the liquid, tubing, operating pressure, and system design.

Can this pump replace a peristaltic pump?

For applications requiring stable, repeatable, and relatively high liquid flow, the LFP4000 Series can be considered as an alternative solution. Final selection should be based on the required flow accuracy, liquid properties, pressure, and system layout.

Is the pump suitable for continuous operation?

The pump is designed for stable operation within its specified working conditions. For continuous-duty applications, please confirm the liquid, pressure, running time, and installation conditions with the LEFOO engineering team.

Are customized connectors available?

Yes. Standard options include 36#, 35# straight connectors, and L-shaped connectors. Other connection options can be customized for OEM projects.
