Kamoer KHS-SV-S40 24V brushed DC motor peristaltic pump
Kamoer KHS-SV-S40 24V brushed DC motor peristaltic pump
The Kamoer KHS-SV-S40 is a precision 24V brushed DC motor-driven peristaltic pump engineered for accurate, pulsation-free fluid transfer in laboratory, medical, and industrial automation applications. Laboratory technicians, biomedical researchers, and process automation engineers rely on this pump for metering corrosive chemicals, viscous fluids, and sensitive pharmaceutical compounds with exceptional accuracy and repeatability. This pump solves the critical challenge of contamination-free, precise dosing in environments where traditional centrifugal pumps introduce shear stress and cross-contamination risks.
Product Overview
The Kamoer KHS-SV-S40 operates on the peristaltic pump principle, where a rotating cam mechanism sequentially compresses a silicone or Tygon tubing to create a one-way flow without the fluid contacting internal pump components. This design eliminates seal leakage, reduces maintenance requirements, and allows seamless handling of aggressive chemicals, biological samples, and pharmaceutical liquids. The 24V brushed DC motor provides consistent torque delivery with variable speed control capability, enabling flow rate adjustments from 0.5 mL/min to 40 mL/min depending on tubing diameter selection and motor speed regulation.
The brushed DC motor architecture delivers immediate response to voltage variation, making this pump ideal for automated control systems and real-time flow adjustment in laboratory setups. The compact S40 form factor integrates easily into benchtop analyzers, automated dispensing systems, and medical infusion devices. Its low noise operation, typically under 70dB, makes it suitable for noise-sensitive laboratory environments. The pump head accepts standard peristaltic tubing connectors, offering flexibility in fluid pathway customization without requiring complete pump replacement.

How to Use
Begin by selecting appropriate peristaltic tubing compatible with your fluid type and chemical properties. Insert the tubing into the pump head's roller compression chamber, ensuring proper seating in the tubing guides. Connect the 24V DC power supply to the motor terminals, observing correct polarity to prevent motor damage. For variable speed control, connect a PWM controller or variable voltage power supply between the 24V source and pump motor. Before operating with critical fluids, prime the tubing by running the pump at low speed for 30 seconds to remove air bubbles and establish consistent flow.
Operate the pump at the minimum voltage and speed required for your application to maximize motor lifespan and reduce noise. Monitor flow rate by collecting output for a timed interval and calculating mL/min, adjusting motor speed as needed to achieve target flow. For continuous operation exceeding 8 hours, ensure adequate ventilation around the motor to prevent thermal stress. After each use with chemical fluids, flush the tubing with compatible solvent or distilled water to prevent residue accumulation and tubing degradation. Replace tubing every 3 to 6 months depending on fluid type and operating hours to maintain accuracy and prevent leakage.
Frequently Asked Questions
What is the maximum pressure rating of the Kamoer KHS-SV-S40 pump?
The maximum pressure depends on tubing selection and ranges from 0.5 bar for flexible silicone tubing to 2 bar for reinforced Tygon tubing. Operating beyond the rated pressure will damage tubing and compromise pump accuracy. Always verify tubing pressure rating before operation and avoid restricting outlet flow which increases back-pressure.
Can I use this pump with aggressive chemicals like concentrated acids and bases?
Yes, the peristaltic design makes the KHS-SV-S40 ideal for aggressive chemicals since fluid never contacts internal pump components. Select tubing material compatible with your specific chemical: Tygon tubing for most acids and bases, PTFE tubing for aggressive organic solvents, and silicone for food-grade applications. Always verify chemical compatibility charts before operation.
How do I control the flow rate of this pump?
Flow rate is controlled by adjusting motor speed through voltage variation. Connect a PWM controller or variable voltage power supply to modulate the 24V input from 0V to 24V, which proportionally adjusts motor RPM and thus flow rate. Most users employ PWM controllers for smooth, noise-free speed adjustment. Tubing diameter also affects flow rate, so select tubing sized for your target flow range.
Is this pump suitable for sterile pharmaceutical applications?
The pump itself is suitable for pharmaceutical use, but sterility depends on your complete system design. Use sterile, single-use tubing for each batch, sterilize the pump head with 70% ethanol or appropriate disinfectant between batches, and operate in a controlled environment. For GMP-compliant pharmaceutical manufacturing, validate the entire system according to your regulatory requirements.
What is the typical lifespan of the brushed DC motor?
With proper operation and maintenance, the brushed motor typically delivers 5000 to 10000 hours of service. Lifespan depends on operating voltage, speed, ambient temperature, and maintenance practices. Operating at lower speeds and voltages than maximum rated values extends motor life significantly. Replace the motor if it exhibits reduced torque, increased noise, or erratic speed control.
