Choosing a mini liquid pump for OEM equipment involves more than comparing maximum flow rates. You also need to consider dosing accuracy, liquid compatibility, installation space, operating pressure, and long-term performance under actual working conditions. A pump that performs well in a water test may deliver different results when connected to restrictive tubing, valves, or chemical-filled fluid paths.
The JSG18 Series 24 V DC mini peristaltic pumps from Shenzhen Jingsuguang Technology Co., Ltd. address these requirements with three flow ranges, reversible operation, and a compact 60 × 54 × 41 mm design. JSG DC PUMP supports OEM customers with model selection, sample validation, and production planning, helping you evaluate a suitable pump configuration before integrating it into your equipment.
What Makes the JSG18 Mini Liquid Pump Suitable for OEM Equipment?
The JSG18 series uses a roller-compressed elastic element rather than a conventional exposed pump tube. This enclosed structure is designed for compact liquid-handling systems where installation space and routine maintenance matter.
The pump operates with a 24 V DC, 28 mm stepper motor. With a suitable stepper driver, you can adjust motor speed, regulate flow, and reverse the pumping direction when your application requires it.
Key features include:
- Three flow ranges: 0.5–50, 0.5–200, and 0.5–400 mL/min.
- Compact dimensions: 60 × 54 × 41 mm across all three models.
- Lightweight construction: 155 g per unit.
- Reversible operation: Direction control through a compatible driver.
- Temperature range: 0–60°C for the specified medium conditions.
- OEM integration: Model selection and sample testing based on your fluid system.
Actual performance depends on the liquid, tubing, pressure, suction lift, and operating cycle. Therefore, validate the pump in your complete fluid path before finalizing the design.
How Do the JSG18 Mini Liquid Pump Models Compare?
Selecting the right miniature liquid pump starts with matching the required flow to the available operating range. The JSG18S suits lower-flow dosing, while the JSG18L and JSG18H support progressively higher flow requirements.
| Specification | JSG18S | JSG18L | JSG18H |
|---|---|---|---|
| Flow range | 0.5–50 mL/min | 0.5–200 mL/min | 0.5–400 mL/min |
| Speed range | 3–260 rpm | 3–1,050 rpm | 3–2,100 rpm |
| Rated current | 1.0 A | 1.0 A | 1.0 A |
| Maximum suction lift* | 6 m | 8 m | 9 m |
| Maximum discharge head* | 10 m | 20 m | 30 m |
| Noise level* | ≤38 dB | ≤38 dB | ≤38 dB |
| Dimensions | 60 × 54 × 41 mm | 60 × 54 × 41 mm | 60 × 54 × 41 mm |
Reference specifications are based on pure-water testing at 20°C. Maximum flow, suction lift, and discharge head are separate test points, not simultaneous operating guarantees.
Which Model Should You Choose?
- JSG18S: Consider this model for low-flow reagent dosing and small-volume dispensing.
- JSG18L: Evaluate it for sampling and medium-flow liquid transfer.
- JSG18H: Consider it when your system requires higher transfer rates within the specified flow range.
Where Can a 24V Mini Peristaltic Pump Be Used?
A miniature liquid pump can support several OEM applications, provided the selected model meets the fluid, environmental, and regulatory requirements.
Medical and laboratory analyzers: Use the JSG18 platform as a candidate for reagent dosing, sample handling, and drainage functions after application testing. For example, a chemical oxygen demand (COD) analyzer may require a controlled 5 mL reagent dose per cycle.
Water-quality monitoring: The pump can be evaluated for water sampling and condensate transfer. Appropriate inlet filtration helps prevent hard particles from damaging the elastic element.
Disinfection equipment: A dosing system may use the pump to deliver a working solution at a defined flow rate. However, sodium hypochlorite and other chemicals require specific material-compatibility testing before production.
The published specifications do not establish universal chemical compatibility or medical-device certification. Confirm the wetted materials and applicable compliance requirements for your application.
How to Select and Validate Your Mini Liquid Pump
Follow these steps to reduce integration risks before purchasing pumps for an OEM project.
- Define the working point. Specify the target flow under operating pressure or vacuum, required dose volume, and acceptable variation.
- Confirm fluid compatibility. Provide the liquid composition, concentration, temperature, and filtration requirements.
- Check electrical and mechanical interfaces. Verify the 24 V DC supply, driver current, control signals, mounting space, and tubing dimensions.
- Evaluate a sample. Measure flow using your actual liquid and complete fluid path. Check pressure effects, pulsation, noise, and operating temperature.
- Approve production conditions. Document the selected model, test method, acceptance criteria, and duty cycle before pilot production.
For installation, the JSG18 ports have a specified 6.3 mm outside diameter. The product instructions identify 5 or 5.5 mm ID soft tubing, secured with suitable clamps or cable ties. Avoid clamping the pump head or blocking the outlet.
Why Work With JSG DC PUMP?
Shenzhen Jingsuguang Technology Co., Ltd. has manufactured miniature pumps since 2003. JSG DC PUMP offers air, vacuum, piston, diaphragm, and liquid pump platforms for OEM equipment, together with model selection, customization, sample evaluation, and production support.
The company states that its quality management system is certified to ISO 9001:2015. For your project, engineering review should focus on the actual operating point, electrical interface, material compatibility, and agreed validation criteria rather than maximum specifications alone.
Frequently Asked Questions
1. Can the JSG18 mini liquid pump reverse its flow direction?
Yes. A compatible stepper driver can control the motor direction and speed. Confirm the required control signals and operating sequence during integration.
2. Can this 24V mini liquid pump handle chemicals?
Potentially, but compatibility depends on the chemical, concentration, temperature, and wetted materials. Obtain material confirmation and test the complete fluid path before production.
3. How accurate is the JSG18 pump for dosing?
The supplied specifications do not establish a universal dosing-accuracy guarantee. Calibrate the selected model under actual operating conditions and agree on acceptance criteria with the manufacturer.
Conclusion
The JSG18 mini liquid pump series provides three flow ranges, reversible operation, and a compact 24 V DC design for OEM liquid-handling equipment.
