Choosing the right pump configuration is critical in medical device design. Single-head, dual-head, and multi-head pumps each offer unique performance advantages. BODENFLO helps OEMs match the right configuration to flow, pressure, and redundancy requirements.
Single-head: Simple structure, compact size, cost-effective. Suitable for limited space and applications with moderate flow or vacuum requirements.
Dual-head: Two pump heads can be connected in parallel for higher flow or in series for higher vacuum/pressure, providing smoother and more stable performance.
Multi-head: Three or more pump heads designed for ultra-high flow, long-duty cycles, or redundancy in complex systems.
Single-head: Flow 0.5–45 L/min, vacuum up to -85 kPa
Dual-head: Flow 4–60 L/min, vacuum up to -100 kPa
Multi-head: Flow 5-45 L/min, high vacuum up to -100kpa, strong continuous operation capability
Single-head: Portable NPWT devices, IVD analyzers, dental treatment units, aesthetic/beauty devices
Dual-head: Shockwave therapy devices, oxygen concentrators, rehabilitation systems, lab automation workstations
Multi-head: High-capacity biochemical analyzers, continuous laboratory instruments, multifunction medical platforms
Not necessarily. The choice depends on the required flow, vacuum, and size of your application.
Multi-head configurations are recommended when very high flow, redundancy, or continuous operation is required.
Parallel connection increases flow, while series connection increases vacuum or pressure.
In many cases, yes. However, space, power supply, and control settings need to be checked before replacing the configuration.
Not necessarily. With brushless, oil-free designs like BODENFLO pumps, multi-head systems are still low-maintenance and designed for long life.
Selecting the right motor type is a key factor for performance, durability, and cost in medical pump systems. Brushed, brushless, and coreless motors each serve different application requirements.
Brushed: Simple, low-cost, suitable for intermittent or short-term use. Limited lifespan due to brush wear.
Brushless: Long service life, stable performance, and low noise. Ideal for continuous-duty or precision medical applications.
Coreless: Lightweight with fast response, used in compact, battery-powered devices requiring quick startup.
Brushed: Lifespan 1000–6000 hours, lower cost.
Brushless: Lifespan 5000–10000+ hours, stable continuous operation.
Coreless: Lifespan 6000–8000+ hours,Very fast response, moderate lifespan, used in portable devices.
Brushed: Portable NPWT devices, basic suction units, cost-sensitive instruments.
Brushless: Oxygen concentrators, IVD analyzers, shockwave therapy, lab automation.
Coreless: Handheld aesthetic devices, small portable diagnostic tools.
Brushless motors offer longer life, lower noise, and better reliability, especially for continuous-duty medical equipment.
Yes, but power requirements, speed control, and space constraints need to be considered.
Yes, coreless motors have higher costs due to precision manufacturing but are preferred when weight and fast response are critical.
Brushless motors are recommended for long continuous operation because of their extended lifespan and low maintenance.
BODENFLO offers customization for all motor types, including voltage, speed control, and integrated driver options.
Choosing the right flow rate is not about “bigger is better.”
In medical devices, selecting low-flow or high-flow diaphragm pumps depends on the required volume, cycle time, and the precision of control. Oversized pumps increase cost and noise, while undersized pumps compromise performance.
| Feature | Low-Flow Pumps | High-Flow Pumps |
|---|---|---|
| Flow Range | 0.2 – 5 L/min | 10 – 80 L/min |
| Key Strength | Precision, stable microflow | Fast evacuation, large volume supply |
| Typical Vacuum | Up to -75 kPa | Up to -100 kPa |
| Size & Noise | Compact, very quiet | Larger, higher power, but optimized for low noise |
| Typical Applications | IVD, biochemical analyzers, dental, NPWT | Oxygen concentrators, lab automation, shockwave therapy |
| Guidance Point | Key Recommendation |
|---|---|
| Application Precision | Choose low-flow pumps for instruments that need small, precise volumes such as IVD, biochemical analysis, or portable NPWT. |
| Volume Demand | Choose high-flow pumps for devices that deliver or evacuate large volumes quickly, such as oxygen concentrators or rehabilitation systems. |
| Early Consultation | Consult early: BODENFLO’s engineering team can help calculate exact flow and vacuum parameters during the design stage. |
| Noise Requirements | Lower flow pumps are naturally quieter; high-flow pumps may require brushless or multi-head designs for low-noise operation. |
| Power & Duty Cycle | For 24/7 continuous operation, brushless high-flow pumps with efficient cooling are recommended. |
| System Volume Match | Avoid oversizing: Correctly matched pumps reduce cost, noise, and extend device lifespan. |
