High-Flow Negative Pressure Control for Critical Medical & Surgical Systems

The SC4002PPV (formerly cataloged as SC5003PM) is an industrial-grade, oil-less micro diaphragm vacuum air pump specifically engineered for medical suction devices, negative pressure wound therapy (NPWT) systems, laboratory gas sampling, and automated drainage equipment.

Available in DC 6.0V, DC 12.0V, and DC 24.0V configurations, the upgraded SC4002PPV delivers a robust free air displacement exceeding 10.0 L/min and achieves an ultimate negative pressure below -78 kPa (-585 mmHg). Equipped with a factory-integrated steel mounting bracket, it drastically reduces system vibration and streamlines mechanical assembly in compact clinical carts and portable bedside instruments.

Engineering Advantages for Medical Device Designers

1. Deep Vacuum Generation (<-78 kPa) for Clinical Efficacy

Medical suction units require reliable negative pressure to clear viscous fluids and airway secretions efficiently. The SC4002PPV sustains a continuous vacuum depth beyond -78 kPa, easily fulfilling hospital and emergency aspiration standards while providing solid pressure margins for wound exudate removal in NPWT units.

2. High Flow Rate (>10 L/min) for Rapid Evacuation

With an open flow capacity exceeding 10 L/min, this pump minimizes dead-volume evacuation time in canisters and tubing circuits. Quick pressure establishment allows medical personnel to initiate aspiration instantly during emergency interventions.

3. Upgraded High-Efficiency Motor with Low Thermal Profile

The redesigned motor architecture consumes just 600 mA at 12V and 350 mA at 24V-substantially lower than legacy configurations. Reduced current draw minimizes internal heat dissipation, prolonging battery runtime in portable aspirators and preventing thermal drift near sensitive medical electronics.

4. Pre-Installed Shock-Absorbing Steel Mounting Bracket

Eliminate custom sheet metal tooling costs. The SC4002PPV comes standard with an integrated metal chassis mount featuring four Ø4.0 mm isolation grommet-ready holes. This structural design dampens harmonic resonance within plastic instrument housings, keeping operational noise under 72 dB.

5. 100,000-Cycle Endurance Reliability

Validated through 100,000 continuous stress cycles with periodic exhaust venting, the high-purity diaphragm elastomer and precision bearings ensure dependable multi-year performance without maintenance or vacuum degradation.
