Why a 12 mm Flat Body Matters

Most micro vacuum pumps in this pressure class use a round motor-and-head stack that needs a cylindrical cavity. SC1201XPV uses a rectangular head only 12 mm thick, with four moulded mounting bosses on a 26.8 mm footprint.

• Fits into the handle of a handheld facial device instead of forcing a bulge in the housing.
• Mounts flat against a PCB or chassis wall, so the pump does not dictate the enclosure shape.
• Dual ports (INLET and OUTLET) exit on the same face, keeping tubing runs short and tidy.

Body dimensions are taken from the SC1201XPV drawing. Confirm against the controlled release drawing before committing enclosure tooling.

Vacuum and Flow: What You Actually Get

Free flow and maximum vacuum do not occur at the same time. As suction load rises, flow falls. For a beauty instrument pulling against skin, or a sampler pulling through a filter, plan on the middle of the curve rather than the free-flow headline.

Send us your target vacuum and required flow, and we will confirm where on the curve your application sits. That is faster than discovering it on a prototype.

Battery Life and Cycle Life

The 100,000-cycle rating is measured on a pulsed profile: 5 seconds on, 2 seconds off, 5 seconds exhaust. That is the rhythm many facial suction devices already run at.

Converted to operating time, 100,000 pulses is about 139 hours of actual suction. For a device used 10 minutes a day on a pulsed cycle, that works out to roughly 1,100–1,200 sessions. Ask us for the test report if you need the figure for a warranty statement.

This is a pulsed rating, not a continuous-duty rating. For continuous suction, tell us the duty cycle so we can confirm allowable running time.

Application Notes

Beauty and facial suction instruments

-26 kPa suits pore cleansing, lifting, and lymphatic massage heads where the vacuum is regulated downstream. Two design rules decide whether the pump survives:

• Never let the pump see liquid. This is a dry-running air pump. A droplet or a smear of gel reaching the head will damage the diaphragm and valves. Fit a hydrophobic filter or a liquid trap between the suction cup and the inlet.
• Regulate at the device, not the pump. -26 kPa is the pump's limit, not a safe skin pressure. Use a bleed valve or PWM to set the working level.

Gas sampling and detection

The -26 kPa budget tolerates more inlet restriction than a low-vacuum sampling pump, so short tubing runs, a small filter and a sensor chamber are workable at around 0.7 L/min free flow. Before designing in:

• Confirm wetted-material compatibility if the sample stream contains acid gas, solvent vapour or high humidity.
• Add a buffer volume if the sensor is sensitive to pulsation.
• Check the electrical safety requirements of your enclosure - no explosion-proof certification is published for this pump.

Blood pressure and pneumatic instruments

The same body is used in cuff and pressure-chamber designs where a flat pump fits a slim housing.

Specifications

Design Checklist

• Trap liquids before the inlet. Dry-running air pump - one ingestion event ends the diaphragm.
• Regulate suction at the device. -26 kPa is a pump limit, not a working skin pressure.
• Plan for flow droop. 0.7 L/min is free flow; expect less once a filter and tubing are in line.
• Do not assume continuous duty. The rating is a 5s/2s/5s pulse.
• Check the model suffix. XPV is vacuum/air. Water pumps in this series end in XPW.
• Confirm material compatibility. Air is the declared medium; corrosive or solvent-laden streams need a wetted-material review.
• Mount on the four bosses. Do not clamp the head - the diaphragm chamber is the sealing surface.

Frequently Asked Questions

1. Is SC1201XPV a water pump?

No. It is a vacuum pump for air. Some listings for the previous model number combined the words water and vacuum, which confused. This product has no liquid rating.

2. How much vacuum does it produce?

-26 kPa, which is about -195 mmHg. This is the maximum vacuum at the sealed end; flow falls as suction load increases.

3. Can it run continuously?

The 100,000-cycle rating uses a pulsed profile of 5 seconds on, 2 seconds off, 5 seconds exhaust. For continuous suction, share your duty cycle and ambient temperature so we can confirm allowable running time.

4. Can I use it for a facial vacuum device?

Yes, within limits. Regulate the suction at the device so the skin never sees the full -26 kPa, and fit a liquid trap or hydrophobic filter so gel, mist, or condensation cannot reach the pump head.

5. Can I use it for gas sampling?

The -26 kPa vacuum budget handles short tubing runs and a small filter at around 0.7 L/min free flow. Confirm wetted-material compatibility for the gas you are sampling, and note that no explosion-proof certification is published.

6. Does it need oil?

The drawing declares air as the medium but does not state a lubrication method. Ask us for a written confirmation if your application requires a declared oil-free pump.
