Micro Vacuum Pump SC1804PM (SC2201XPV): Dual-Purpose Diaphragm Air Pump for Blackhead Removers & Breast Pumps
The SC1804PM micro vacuum pump (upgraded model code: SC2201XPV) is a miniature dual-port diaphragm air and vacuum pump engineered by Shenzhen Skoocom Electronic Co., Ltd. (SKOOCOM) for electric blackhead removers, portable breast pumps, wireless mini vacuum cleaners, and handheld cosmetic instruments. Built around a compact Ø22.0 mm × 49.6 mm housing and a high-efficiency FF-130SH flat-profile DC motor, the SC1804PM / SC2201XPV delivers strong negative suction pressure beyond -56 kPa (-420 mmHg) and a free air flow rate exceeding 1.6 L/min. Available in low-power DC 3.7V (<430 mA) and DC 6.0V (<300 mA) configurations with <65 dB quiet operation, it provides OEM appliance manufacturers with reliable dual-purpose suction and inflation performance.
Core Engineering Advantages of the SC1804PM (SC2201XPV) Micro Vacuum Pump
Portable personal-care, maternal-care, and smart cleaning devices demand a micro pump that delivers strong negative pressure immediately upon activation while fitting inside slim, ergonomic handheld enclosures. The SC1804PM (new catalog number SC2201XPV) solves these design constraints through five core engineering features.
Strong Negative Suction Beyond -56 kPa (-420 mmHg) with >1.6 L/min Air Flow
Effective pore cleansing in electric blackhead removers and comfortable milk expression in wearable breast pumps both require rapid vacuum buildup and stable air evacuation. The SC1804PM / SC2201XPV generates a maximum vacuum degree deeper than -56 kPa (approximately -420 mmHg) paired with an open air flow rate of >1.6 L/min (peaking near 1.9 L/min at free flow). This combination ensures rapid evacuation of dead-volume chambers in suction cups, breast shields, and dust canisters without requiring a bulky motor.
Dual-Port Suction and Inflation Architecture (2 × Ø3.5mm Nozzles)
Unlike single-port vacuum pumps that vent exhaust air directly into the device housing, the SC1804PM features two parallel Ø3.5 ± 0.3 mm ports (5.0 ± 0.3 mm nozzle length) on the Ø22.0 mm pump head-one dedicated to vacuum suction (air intake) and the other to positive-pressure inflation (air exhaust). This dual-purpose pneumatic layout gives product designers three distinct integration options:
○Pure Vacuum Suction Mode: Connect the intake nozzle to a blackhead suction head, breast pump flange, or dust nozzle to create controlled negative pressure up to -56 kPa.
○Positive Inflation / Atomization Mode: Connect the exhaust nozzle to inflate medical cuffs, oxygenate micro-chambers, or drive airbrush and nebulizer sprays.
○Closed-Loop Muffler Routing: Route the exhaust port through an internal acoustic damping tube to reduce perceived operating noise below 58–60 dB.

Primary Application Domains for the SC1804PM (SC2201XPV) Micro Vacuum Pump
Electric Blackhead Removers, Pore Cleansers, and Hydradermabrasion Pens
Modern cordless blackhead vacuum removers and portable hydro-dermabrasion beauty instruments require precise, multi-gear suction control ranging from -15 kPa (for sensitive cheek skin) up to -55 kPa (for stubborn T-zone comedones and acne extraction). The SC1804PM's <-56 kPa peak vacuum provides ample headroom for 3-speed or 5-speed PWM electronic pressure regulation. At the same time, its 49.6 mm length and Ø22 mm diameter slide effortlessly into pen-style ergonomic beauty wands alongside a single 3.7V lithium battery. In hydro-dermabrasion pens, the pump's dual Ø3.5 mm ports allow simultaneous waste-liquid vacuum recovery and clean-solution pneumatic delivery.
Wearable and Portable Electric Breast Pumps
Maternal-care appliance brands designing wearable, in-bra, and portable electric breast pumps prioritize two performance metrics above all else: natural rhythmic suction (-10 kPa to -40 kPa) and discreet, low-noise operation (<60 dB) so mothers can pump at night or in office environments without disturbance. In the -10 kPa to -35 kPa physiological expression range, the SC1804PM / SC2201XPV maintains 0.80–1.40 L/min of responsive air displacement-enabling fast cycling during the 2-minute high-frequency "stimulation/let-down phase" and smooth, steady holding during the "expression phase." Because its diaphragm chamber is 100% oil-free, it eliminates any risk of hydrocarbon vapor contaminating breast milk collection kits.
Wireless Mini Vacuum Cleaners, Desktop Dust Blowers, and Keyboard Cleaners
As explicitly highlighted in the SC2201XPV / SC1804PM engineering specification sheet, wireless vacuum cleaners (including desktop crumb sweepers, car interior mini vacuums, keyboard dust extractors, and cosmetic brush cleaners) represent a major application domain. While mini centrifugal fan blowers lose suction immediately when debris partially blocks the nozzle, the SC1804PM positive-displacement diaphragm pump builds up to -56 kPa of static pull to dislodge trapped dust from deep crevices. Moreover, by utilizing both the intake and exhaust Ø3.5 mm nozzles, handheld cleaning tools can function as a 2-in-1 vacuum suction and compressed-air dust blower.
Portable Cupping Massagers, Lymphatic Drainage, and Handheld Vacuum Sealers
Beyond facial pore care and maternal nursing, the SC1804PM powers smart electric cupping therapy devices, eye-area micro-vacuum massagers, and portable food/cosmetic vacuum storage pumps. Its 400-cycle heavy-duty endurance rating (30 minutes ON, 10 minutes OFF = 200 hours of cumulative run time) translates into 4,000+ three-minute beauty or cupping sessions, ensuring exceptional product longevity and low warranty return rates for global consumer electronics brands.

Frequently Asked Questions About the SC1804PM (SC2201XPV) Micro Vacuum Pump
1. Are SC1804PM and SC2201XPV the same micro vacuum pump?
Yes. SC1804PM is the legacy model number and SC2201XPV is SKOOCOM's updated catalog model number for the same Ø22.0 mm × 49.6 mm dual-port micro vacuum pump. They have identical mechanical mounting dimensions, 2 × Ø3.5 mm air nozzles, <-56 kPa vacuum performance, and electrical specifications, making them 100% drop-in compatible.
2. Is the SC1804PM (SC2201XPV) suitable for both electric blackhead removers and breast pumps?
Yes. With a maximum vacuum degree deeper than -56 kPa (-420 mmHg) and a free air flow rate of >1.6 L/min, the pump covers both the high-suction range needed for blackhead and comedone extraction (-35 to -55 kPa) and the gentle, rhythmic negative pressure required for portable electric breast pumps (-10 to -35 kPa) when paired with PWM voltage control or a micro solenoid air release valve.
3. Can this pump be used for both vacuum suction and positive-pressure inflation?
Yes. Because the pump head features two independent Ø3.5 ± 0.3 mm nozzles (an air intake port and an air exhaust port), it operates as a true dual-purpose micro air pump. Engineers can use the intake port for vacuum extraction, the exhaust port for inflation/blowing, or both ports simultaneously in closed-loop circulation and hydro-dermabrasion systems.
4. What is the actual noise level of the SC1804PM during normal suction operation?
While the maximum specification ceiling is rated at <65 dB (measured at 30 cm), the actual laboratory performance curve shows that operating noise stays between 56 dB and 60 dB across the entire 0 kPa to -60 kPa vacuum curve. When enclosed in a breast pump or beauty instrument shell with a silicone damping sleeve, perceived noise typically drops to 45–50 dB or below.
5. How can I request SC1804PM / SC2201XPV samples or custom voltage specifications?
You can request engineering samples (in DC 3.7V, DC 6.0V, or custom voltages such as DC 3.3V / 5V / 12V) directly from Shenzhen Skoocom Electronic Co., Ltd. by submitting the inquiry form on this page or emailing marketing@skoocom.com with your target application, voltage, and annual volume requirements.
