SC2201XPW Micro Diaphragm Water Pump for Oral Irrigators and Water Flossers
DC 3.0V / 6.0V | 0.7 L/min | >15 Psi | <60 dB | ø22 mm slim body
SC2201XPW is a ø22 mm diaphragm water pump built for handheld oral cleaning devices. It moves 0.7 L/min at more than 15 Psi from a 3.0V or 6.0V supply, drawing under 150 mA at 6V, and runs at under 60 dB at 30 cm. The 50-second-on / 20-second-off qualification cycle matches a single irrigation session, and 15,000 qualified cycles correspond to roughly 208 hours of pumping. Former model number: SC1801PW.

- Current: <350 mA at 3V / <150 mA at 6V

Why SC2201XPW Suits Handheld Oral Cleaners
Duty cycle written for a single irrigation session
The qualified life test runs 50 seconds on, 20 seconds off. That is the shape of real use: one fill, one cleaning cycle, a pause, then the next use. The pump is not rated on a hypothetical continuous run that no oral device ever performs.
About 12,500 sessions from one pump
15,000 cycles × 50 seconds equals roughly 208 hours of cumulative pumping. At one minute per session, that is about 12,500 sessions, or more than 17 years at twice-daily use. The figure is a cycle-count conversion, not a continuous-duty hour rating.
Under 150 mA at 6V for battery-powered handles
At 6.0V the pump draws less than 150 mA, and at 3.0V less than 350 mA. Both rails suit single-cell lithium or two-cell alkaline architectures without a boost stage, which keeps handle weight and charging time down.
ø22 mm body for slim handles
69.1 mm overall length on a ø22 mm head with a ø20.4 mm motor leaves room for the battery and PCBA inside a handheld handle. A 15 mm flat on the head base provides anti-rotation location.
Quiet enough to hold near the head
Measured under 60 dB at 30 cm. Because the pump sits in the hand rather than on a bench, mounting isolation matters more than the bare figure - see the selection notes below.
Steady flow instead of a piston pulse
A diaphragm head delivers a smoother flow than a piston pump of the same size. If your product depends on a sharp pulsating jet for plaque disruption, specify your pulse requirement up front; this model is qualified for steady delivery, and no pulse profile is published.

PS. Rated values apply to clean water at ambient temperature. Dimensions follow the SC2201XPW engineering drawing and should be checked against the controlled 2D drawing before mechanical design release.
Where This Model Fits
Handheld oral irrigators and portable water flossers
Low-voltage supply, compact body, and a 50-second duty cycle suit cordless handles. Flow of 0.7 L/min fills a 200 mL reservoir in about 17 seconds, so a single fill covers a normal session with margin.
Gentle-rinse and gum-care devices
At >15 Psi (≈1.03 bar), the delivered jet is gentle rather than sharp. Products designed around a soft rinse, gum massage or paediatric use fit this pressure band better than devices specified for high-pressure pulsation.
Water purifiers, dispensers and beverage intake
The same hydraulic platform also serves low-flow intake duties in purifiers, tea and coffee machines, drinking fountains and ice machines, where 0.7 L/min and >15 Psi are sufficient to push through inline filters and narrow tubing.
When a different model is the better answer
If your device needs 30–60 Psi for a high-pressure jet, or is a dental chair or ultrasonic scaler water circuit, this model is below that pressure band. Specify your target pressure and flow, and we will point you to the matching pump rather than force this one into the application.
Selection Notes for Oral Care Design
- Confirm your pressure band first. >15 Psi suits gentle rinse devices. High-pressure flossers need a higher-pressure model.
- Wetted materials need sign-off. The fluid path is specified for water; request the material declaration for the diaphragm, valve, and housing before release to a potable-water product.
- Plan drainability and stagnation. Water left in the head between sessions is a hygiene question. Design the reservoir and tubing route so the line can be emptied, and specify a flush routine.
- Isolate the mount. The 60 dB figure is measured in free air at 30 cm; a hard-mounted pump in a hollow handle will transmit more. Use a compliant grommet.
- Respect the duty cycle. 50 s on / 20 s off is the qualified profile. Longer continuous runs raise motor temperature and are outside the released specification.
- Match tubing to the ø4.8 mm port. Use 3.0–3.5 mm ID flexible tubing; a loose fit will leak at 15 Psi.
- Do not confuse neighbouring part numbers. SC2201XPW is a water pump. SC2201XPV is a vacuum air pump used for suction duties. They are not interchangeable.

Frequently Asked Questions
1. What pressure does it actually deliver?
More than 15 Psi, approximately 1.03 bar or 10.5 m of water head. Some earlier catalogue pages quoted 30 psi; that figure does not match the current engineering drawing and should not be used for system design.
2. How long does the pump last in real use?
15,000 qualified cycles at 50 seconds on and 20 seconds off, equal to about 208 hours of cumulative pumping. At one minute per session, that is roughly 12,500 sessions.
3. Can it run continuously?
The released specification is the 50 s on / 20 s off profile. Continuous operation is outside that qualification; if your product needs longer runs, tell us the duty, and we will review motor options.
4. Is it suitable for a high-pressure water flosser?
Only if your target jet pressure is within the >15 Psi band. Devices specified for 30–60 Psi need a different model. Send the target pressure and flow, and we will confirm the match.
5. What is the difference between SC2201XPW and SC2201XPV?
SC2201XPW is a water pump that moves liquid. SC2201XPV is a vacuum air pump for suction. The part numbers differ by one letter, and the products are not interchangeable.
6. Can it pump liquids other than water?
The released medium is water. Detergents, solvents, or beverages require a material compatibility review of the diaphragm, valves, and housing before use.
Send Pressure, Flow and Reservoir Size
Tell us your target jet pressure, flow, voltage rail, reservoir volume, duty cycle, and annual volume. We will confirm the pump variant and the wetted-material declaration.
