Brand: SKOOCOM
SKU: 150211425

Current Standard Model: SC2201XPW | Old Model: SC1801PW (Direct Drop-in Replacement)

Food-safe miniature diaphragm water pump engineered specifically for water purifiers, automatic drinking water dispensers, and beverage intake systems requiring 0.7 L/min splash-free flow, >15 Psi head pressure, whisper-quiet <60 dB operation, and 15,000-cycle dispensing durability.

Built for Smooth Intake & Clean Delivery in Water Dispensing Appliances

0.7 L/min (700 mL/min) Splash-Free Intake Flow: Optimally calibrated for drinking dispensers, filling a 250mL cup in 20 seconds without turbulent bubbling or scalding liquid splash.
Robust >15 Psi Head Pressure: Easily drives water through inline sediment pre-filters, carbon blocks, and narrow tubing without flow rate choking or stalling.
Food-Contact Safe & Oil-Free Fluid Path: Molded from sanitary engineering polymers and high-grade EPDM diaphragms, ensuring zero heavy metal leaching and no lubricant contamination into direct drinking water.
Ultra-Slim ø22.0 mm Tubular Footprint: 69.1mm length with an ultra-narrow 22mm diameter profile integrates seamlessly into vertical water intake risers, bottle pumps, and compact countertop appliances.
15,000-Cycle Extended Duty Endurance: Tested under an intensive 50-second continuous pumping / 20-second resting duty cycle to simulate years of residential drinking water service.
Low-Voltage High Energy Efficiency: Draws only <150 mA at 6.0V DC and <350 mA at 3.0V DC, maximizing battery run-time in wireless portable water pumps.

Application Focus: Precision Fluid Intake & Domestic Water Appliances

1. Under-Sink & Countertop Water Purifiers

In residential water purification and filtration appliances, water must be pulled through multi-stage pre-filters and pushed into dispensing faucets smoothly. SC2201XPW provides steady 0.7 L/min water displacement with >15 Psi head pressure, easily overcoming internal membrane resistance without producing water-hammer pulsation or line vibration.

2. Instant Heating Water Dispensers & Tea Makers

Precision thermal boilers require constant, unvarying water feed rates to prevent boiling dry or fluctuating output temperatures. The calibrated 700 mL/min delivery rate matches standard heating tube thermal outputs, guaranteeing uniform hot water flow into cups without scalding splattering.

3. Portable Bottle Water Dispensers & Oral Cleaners

With an ultra-low 150mA current draw at 6V DC and a compact ø22 mm diameter, SC2201XPW is ideal for lithium-battery-operated water pumps mounted on 5-gallon water carboys, as well as handheld oral dental irrigators requiring gentle, controlled water jet delivery.

Company introduction

Skoocom Manufacturing Precision & Supply Chain Reliability

Founded in 1998, Shenzhen Skoocom Electronic Co., Ltd. is recognized as a National "Little Giant" enterprise by the Ministry of Industry and Information Technology. For over 26 years, we have specialized in custom micro-pumps and precision valves, partnering with over 1,500 enterprise clients globally across domestic appliance, medical, and industrial sectors.

Dual Production Hubs (50,000+ m²)

Operating manufacturing facilities in Songshan Lake (Dongguan) and Zhong'an Industrial City (Zhaoqing), our 500+ workforce and automated assembly lines maintain an annual manufacturing capacity exceeding 50 million pump and valve units.

FAQ

Q: Why Does Our Original Specification Document State 12V, Whereas SC2201XPW Is Rated At DC 3V And 6V?

A: The legacy web page URL contained a historical typo, labeling it as 12V. SC2201XPW is officially optimized for DC 3.0V and DC 6.0V low-voltage rails, maximizing battery life and reducing thermal dissipation in domestic appliances. If your system strictly requires a 12V DC pump, please consult our higher-voltage micro water pump series (such as SC2202XPW).

Q: Can SC2201XPW Directly Replace The Legacy SC1801PW?

A: Yes. SC2201XPW is the upgraded direct successor to the legacy SC1801PW. All key envelope dimensions (69.1mm length, ø22.0mm head diameter, ø4.8mm port spigots) are 100% form-fit-function backward compatible, allowing seamless drop-in upgrades without modifying your existing tooling.

Q: What Tubing Dimensions Should Be Paired With the Ø4.8mm Nozzles?

A: We recommend food-grade silicone or TPE tubing with an Inner Diameter (ID) of 3.0mm to 3.5mm and an Outer Diameter (OD) of 5.0mm to 6.0mm. The ø4.8mm barbed nozzle provides a secure, leak-free interference fit that holds against >15 Psi water pressure.
