Description
The micro water pump 3V is an ideal solution for water dispensers, providing a steady and consistent water flow between 50–120 mL/min. Its compact size and lightweight design allow easy integration into tight spaces within appliance housings, while its quiet operation (≤66 dB) ensures it won't disturb home or office environments. With low power consumption of 0.9W, it helps maintain energy efficiency in continuous-use applications such as water dispensers, supporting reliable cold and hot water dispensing without overheating or performance drop.
When installed as an air conditioning drainage pump, this small water pump effectively prevents water accumulation and leakage in AC units. Its suction head of ≥0.2m and ability to handle pressure up to ≥15 PSI enable it to remove condensate efficiently, even in vertical or constrained installation setups. The pump's durable construction supports continuous operation, which is essential for humid climates or high-usage environments, helping to extend the lifespan of air conditioning systems by avoiding water-related damage.
We support full customization for this electric diaphragm pump to meet specific requirements, ensuring high quality and reliability in every unit. As a trusted mini water pump factory, we guarantee durable products tailored to your needs.
FAQ - Micro water pump 3v
Q1: Can this pump be used with liquids other than water?
A: Yes, this micro water pump 3V can handle low-viscosity, chemically compatible liquids similar to water, such as certain aqueous solutions, light oils, or alcohol-based fluids. It is not designed for corrosive chemicals, high-viscosity liquids, or fluids containing particulates or abrasives, as these may damage internal components or impair the pump's longevity. For applications involving non-water fluids, compatibility testing under intended conditions is recommended to ensure reliability and performance.
Q2: What factors influence its flow rate variability?
A: The flow rate of 50–120 mLPM is influenced by input voltage, system backpressure, tubing length, inner diameter, and liquid viscosity. Operating at the full 3V with minimal restriction delivers the highest flow, while increased resistance, lower voltage, or longer tubing reduce output. To achieve consistent flow, ensure stable power supply, minimize tubing length and bends, and operate within the specified 0–15 PSI pressure range. System design should account for these variables to match desired flow performance.
Q3: How does the 3V operation affect power efficiency in battery-powered applications?
A: Operating at 3V provides significant power efficiency advantages in battery-operated systems. The pump draws ≤300mA at 3V, consuming only 0.9W total power. This low power consumption allows extended operation on small batteries, making the water pump mini suitable for portable devices where battery life is critical. The lower voltage also reduces heat generation and allows for simpler, more compact power management circuits. For applications requiring longer runtime over maximum flow rate, the 3V configuration of this small diaphragm dc water pump represents an optimal balance between performance and energy efficiency.
