Product Description
The DG Series Miniature Electric Diaphragm Pump is a compact, high-precision positive displacement pump designed for small-flow, low-pressure fluid transfer scenarios. As a miniaturized variant of electric diaphragm pumps, it integrates a lightweight electric motor (typically 12V/24V DC or 110V/220V AC) with a durable diaphragm mechanism, featuring a small footprint (usually less than 20cm in length) and low weight (around 1-3kg)ideal for decentralized, space-constrained applications where portability and easy installation are required.
Constructed with corrosion-resistant materials (e.g., PP pump head, EPDM diaphragm), the series offers strong compatibility with non-corrosive to slightly corrosive media, such as tap water, dilute detergents, aquarium water, and light industrial coolants. Its diaphragm-driven design ensures gentle fluid transfer, avoiding shear damage to sensitive media (like biological samples or low-viscosity adhesives), while the electric drive eliminates the need for compressed air, making it suitable for indoor, lab, or home-use scenarios where air supply is unavailable.
Key performance highlights include a stable flow range of 0.1-5 L/min, a maximum head of 5-15 meters, and low noise operation (below 60dB), along with self-priming capability (suction lift up to 3 meters) for hassle-free startup. It is widely used in fields like laboratory liquid transfer, aquarium water circulation, household appliance water supply (e.g., small humidifiers), and small-scale agricultural irrigation (e.g., potted plant watering).
Dialogue: Key Questions About DG Series Miniature Electric Diaphragm Pump
Q: What makes the "miniature" design of the DG Series stand out compared to standard electric diaphragm pumps?
A: The biggest advantage is its space-saving and portable nature. Standard electric diaphragm pumps are often bulky (over 30cm long) and heavy (5kg+), which limits their use in small spaces. The DG Series, however, is miniaturized to fit in tight spotslike inside laboratory cabinets or small appliancesand weighs only 1-3kg, so it can be easily moved or mounted on walls. This makes it perfect for scenarios where you dont have room for large equipment, such as home aquarium maintenance or lab bench-top fluid transfer.
Q: Can it be used for both indoor home scenarios and light industrial tasks?
A: Yes, its highly versatile across these two areas. For home use, it works great for aquarium water changes (its gentle flow wont disturb fish) or small humidifier water supply (the corrosion-resistant PP material prevents rust contamination). For light industry, its suitable for transferring low-viscosity coolants in small machine tools or dosing dilute cleaning agents in mini assembly linesits 0.1-5 L/min flow range and 5-15m head perfectly match the small-scale needs of these tasks, while the electric drive ensures consistent performance without relying on industrial air systems.
Q: Is it easy to maintain for users with limited technical experience?
A: Absolutely. Unlike complex industrial pumps that require professional disassembly, the DG Series has a user-friendly maintenance design. The pump head can be opened with just a few screws, and the diaphragm (a key wearable part) can be replaced in 5-10 minutes without special tools. Plus, it has dry-run protection in some modelsif the fluid runs out temporarily, the pump wont be damaged, which reduces the risk of user error during operation. Even those with little technical knowledge can maintain it easily.
