KHM-SV3S40 Kamoer Pump 24V BRUSHED(SV) 0.4A-S40 -580ml/min|Silicon tube 4*7.2
The KHM-SV3S40 is a precision peristaltic pump designed for accurate fluid transfer in laboratory, medical, and industrial automation applications. This 24V brushed DC motor pump delivers a consistent flow rate of 580ml/min with low pulsation, making it ideal for dosing, sampling, and continuous circulation tasks. Engineers and technicians rely on this pump for its reliability in demanding environments requiring precise volumetric control and chemical compatibility with silicon tubing.
Product Overview
The Kamoer KHM-SV3S40 operates on the peristaltic pump principle, where a rotating cam mechanism progressively compresses and releases the silicon tube to create positive displacement flow. This design ensures zero backflow, eliminates cross-contamination, and provides exceptional accuracy without requiring check valves. The brushed DC motor architecture delivers consistent torque at 24V with a current draw of 0.4A, making it suitable for battery-powered and regulated power supply applications in field and laboratory settings.
The pump features a robust construction with medical-grade silicon tubing (4mm inner diameter, 7.2mm outer diameter) that resists degradation from repeated compression cycles and maintains flexibility across temperature ranges. The brushed motor design offers cost-effectiveness while providing sufficient power for continuous operation. The compact form factor and lightweight construction make it ideal for integration into automated systems, analytical instruments, and portable medical devices where space and weight constraints are critical.

How to Use
Begin by inserting the medical-grade silicon tubing (4mm ID x 7.2mm OD) into the pump head, ensuring the tube seats properly in the peristaltic compression chamber. Connect the 24V DC power supply to the pump terminals, observing correct polarity to prevent motor damage. For optimal performance, ensure the tubing is not kinked or twisted, as this restricts flow and increases motor load. The pump operates at 580ml/min under standard conditions; actual flow may vary slightly based on fluid viscosity, back pressure, and tubing condition.
To maximize pump lifespan, avoid running the pump dry or against excessive back pressure exceeding the motor's rated torque. For applications involving aggressive chemicals, verify silicon tubing compatibility before operation. Periodically inspect the tubing for signs of degradation, cracks, or permanent deformation, and replace as needed to maintain accuracy and prevent leakage. If the pump will be idle for extended periods, store it with the tubing removed and the motor in a dry environment to prevent deterioration and ensure reliable startup when needed again.
Frequently Asked Questions
What is the maximum back pressure this pump can handle?
The KHM-SV3S40 is designed for low-pressure applications typical of peristaltic pumps. Maximum back pressure depends on tubing wall thickness and motor torque, generally ranging from 0.5 to 1.5 bar for standard silicon tubing. Exceeding recommended pressure reduces motor lifespan and flow accuracy. For high-pressure applications, consider upgrading to reinforced tubing or a higher-specification pump model.
Can this pump handle viscous fluids or slurries?
The peristaltic design handles viscous fluids better than centrifugal pumps due to positive displacement. However, highly viscous fluids increase motor load and reduce flow rate below the rated 580ml/min. Slurries with large particles may damage the tubing or jam the pump mechanism. Test with your specific fluid and monitor motor current to ensure it does not exceed 0.4A continuously.
How often should I replace the silicon tubing?
Silicon tubing lifespan depends on compression frequency, chemical exposure, and storage conditions. With regular use in compatible applications, expect 6 to 12 months of service before noticeable degradation. Inspect tubing monthly for cracks, permanent deformation, or discoloration. Replace immediately if leakage occurs or flow accuracy drops, as worn tubing compromises pump performance and may contaminate your fluid system.
Is this pump suitable for sterile or pharmaceutical applications?
The medical-grade silicon tubing meets biocompatibility standards for many pharmaceutical applications. However, for sterile or injectable applications, verify compliance with your specific regulatory requirements (USP, EP, or ISO standards). The pump itself should be used with appropriate sterilization protocols and validated cleaning procedures to maintain product integrity and safety.
