TM30A-D TM30A-D12-P12004 (with external controller) TM30A-D12-V7004 (with external controller) 6/12/24 0.4/0.24/0.15 120 -70 5

"P" stands for pressure pump, "V" for vacuum pump, and "6/12/24" indicates optional voltages.

Pump Weight: 250g; Pump Size: 80mm x 30.5mm x 58mm; Inlet & Outlet: OD 4.8mm / ID 2.6mm, hose suggestion: ID 4.0mm

Super silent operation (< 50dB at 1 meter); Materials: Pump head - Nylon, Membrane - EPDM/PTFE, Valve - EPDM/FPM. Good resistance to alcohol, acid, alkali, oxidants, ketones, and fats. Poor oil resistance.

Motor type and code: "C" = Coreless brushless DC motor with dual ball bearings (long life >15,000 hours). "D" = Coreless brushless DC motor with dual ball bearings + external controller (same lifetime). Pumps with external controllers support PWM 0â€“5V speed control, braking, and instant start-up. Internal controllers have no additional functions.

**Our Micro Diaphragm Pumps are available with different drive motors.** - **A â€“ Premium Duty Brush DC Motor**: Lifetime of 3,000 hours, longer than standard DC membrane pumps. - **B â€“ Economical Brush DC Motor**: Lifetime of 1,500 hours. - **C â€“ Coreless Brushless DC Motor**: No brushes, vibration-free, nearly silent, highly dynamic, and extremely durable, ideal lifespan of 15,000 hours. - **D â€“ Coreless Brushless DC Motor with External Controller**: Combines all advantages of C, plus advanced control features such as PWM 0â€“5V speed adjustment, braking, and instant starting. - **H â€“ Brushless DC Motor**: Long lifespan of 10,000 hours. **Applications:** TOPSFLO pumps are widely used in the following areas: 1. Industrial pressure and vacuum applications 2. Portable analytical instruments 3. Medical diagnostic equipment 4. Air quality sampling monitors 5. Respiration monitors 6. Gas or odor leak detectors We are a manufacturer and sincerely hope to receive your inquiries and suggestions. Your feedback will help us better serve you. Thank you and best regards!
