Kamoer KHS-SW-S40 12V brushed DC motor peristaltic pump
The Kamoer KHS-SW-S40 is a precision 12V brushed DC motor-driven peristaltic pump engineered for accurate, pulse-free fluid transfer in laboratory, medical, and industrial automation applications. This compact pump delivers consistent flow rates between 0.5 to 40 mL/min with minimal pulsation, making it ideal for pharmaceutical dispensing, aquarium dosing, and analytical instrumentation where precision matters. The brushed DC motor provides reliable operation with variable speed control, eliminating the need for external flow regulators in most applications.
Product Overview
The Kamoer KHS-SW-S40 operates on the peristaltic pump principle, where a rotating rotor with rollers sequentially compresses a flexible silicone tube, creating a one-way flow without the fluid contacting internal pump components. This design ensures chemical compatibility with aggressive liquids, eliminates cross-contamination, and requires minimal maintenance. The 12V brushed DC motor provides direct voltage control for speed adjustment, allowing operators to fine-tune flow rates in real-time without additional controllers. The pump head accommodates standard silicone tubing with inner diameter ranging from 1.6mm to 2.4mm, offering flexibility for different viscosity fluids from water-thin solutions to moderate-viscosity reagents.
The S40 model designation indicates a maximum flow capacity of 40 mL/min at full motor speed, with proportional flow reduction at lower voltages. The brushed motor design delivers consistent torque across the operating range, ensuring reliable performance in temperature-controlled laboratory environments and field installations. Built with corrosion-resistant materials and sealed bearing assemblies, this pump withstands continuous operation in humid conditions and chemical-rich environments. The compact form factor makes it suitable for integration into automated liquid handling systems, environmental monitoring equipment, and medical infusion devices where space constraints exist.

- Research laboratories for cell culture media perfusion, bioreactor nutrient feeding, and continuous sampling applications requiring pulse-free flow
How to Use
Installation begins with selecting appropriate silicone tubing with inner diameter between 1.6mm and 2.4mm, inserting it into the pump head cartridge until fully seated. Connect the two motor leads to your 12V DC power source, ensuring correct polarity for forward flow direction. For variable speed operation, connect the positive lead through a PWM controller or variable voltage supply rather than directly to the power source. Prime the tubing by running the pump for 10-15 seconds at low speed to remove air pockets before connecting to your application system. Verify smooth rotation without grinding sounds, which would indicate improper tubing seating or internal debris.
During operation, monitor the tubing for signs of wear or degradation, as silicone tubes degrade with exposure to certain chemicals and UV light. Replace tubing every 3-6 months depending on chemical exposure and continuous operation hours. For applications requiring precise flow rates, calibrate the pump by measuring actual output volume at your intended operating voltage over a fixed time period, then adjust voltage accordingly. Maintain the pump in a temperature-controlled environment between 5 and 40 degrees Celsius to ensure consistent motor performance and prevent thermal drift in flow rate accuracy. Clean the pump head exterior with a damp cloth after use, and store with the tubing removed to prevent permanent compression set in the silicone.
Frequently Asked Questions
What is the difference between peristaltic and centrifugal pump designs for laboratory applications?
Peristaltic pumps like the KHS-SW-S40 compress tubing sequentially to move fluid without internal contact, making them ideal for aggressive chemicals, sterile applications, and low-pulsation requirements. Centrifugal pumps use rotating impellers and require internal seals, limiting chemical compatibility and producing higher pulsation unsuitable for precision analytical work. Peristaltic pumps excel in laboratory settings where sample integrity and chemical compatibility are critical, while centrifugal pumps are better for high-volume, low-precision applications.
Can I use the KHS-SW-S40 with thick or viscous fluids?
The KHS-SW-S40 is rated for fluids up to moderate viscosity with a maximum pressure rating of 0.5 bar. For highly viscous fluids like glycerin or oils, flow rate will decrease significantly and motor torque requirements increase, potentially reducing motor lifespan. Test your specific fluid at low speed first to verify adequate performance. For viscous fluids exceeding 500 cP, consider larger tubing diameters or dedicated high-viscosity pump models with higher pressure ratings.
How do I control the flow rate precisely without a PWM controller?
The KHS-SW-S40 flow rate is directly proportional to motor speed, which is proportional to applied voltage. Using a variable DC power supply, you can adjust voltage from 0 to 12V to achieve proportional flow rate changes. For example, 6V typically delivers approximately 20 mL/min, while 3V delivers approximately 10 mL/min. Calibrate your specific pump at your intended operating voltages by measuring actual output over a fixed time period, then create a voltage-to-flow-rate lookup table for your application.
What tubing materials are compatible with the pump?
The KHS-SW-S40 is designed for silicone tubing with inner diameters from 1.6mm to 2.4mm. Silicone is chemically inert and compatible with most laboratory reagents, pharmaceuticals, and aqueous solutions. For specialized applications with aggressive solvents like toluene or acetone, verify silicone compatibility first. Do not use PVC or latex tubing, as they degrade rapidly with the peristaltic compression action and may leach plasticizers into your fluid.
