1. What are the key applications of the DC 370 micro diaphragm water pump?

Answer: The DC 370 micro diaphragm water pump is a versatile, self-priming pump widely used in industries requiring precise fluid control. Common applications include medical devices (e.g., blood pressure monitors), domestic appliances (e.g., coffee machines, water dispensers), smart cleaning tools (e.g., electric mops), and DIY projects like automatic plant watering systems. Its food-grade compatible materials make it safe for beverage and health-related equipment.

2. Can the 12V DC 370 water pump run dry without damage?

Answer: Yes, one of the primary advantages of the diaphragm design in the 370 series is its ability to run dry for short periods. Unlike centrifugal pumps, the self-priming diaphragm mechanism does not require liquid to be present in the chamber to start. However, to maximize the motor’s lifespan and avoid overheating, continuous dry running for extended periods is not recommended.

3. What is the self-priming height and flow rate of the Pinmotor 370 pump?

Answer: The Pinmotor 370 micro water pump typically features a self-priming height of up to 1-2 meters (approx. 3.3-6.6 feet) and a flow rate ranging from 0.5 to 1.2 Liters Per Minute (LPM), depending on the specific voltage and load. This makes it an ideal choice for compact systems that require the pump to be mounted above the liquid source.

4. How long is the service life of a 12V 370 micro water pump?

Answer: The service life depends on the motor type used. A standard 370 pump equipped with high-quality carbon brushes typically offers a lifespan of 500 to 1,000 hours of continuous operation. For industrial-grade requirements, Pinmotor offers customized versions with optimized brush structures and heat-resistant materials to ensure stability under long-term duty cycles.

5. What is the difference between the 370 water pump and a 370 air pump?

Answer: While they share the same motor size and external housing, the internal valve structure and diaphragm material differ significantly. The 370 water pump is optimized for liquid viscosity and pressure sealing to prevent leaks, whereas the 370 air pump is designed for gas compression and vacuum tasks. Using an air pump for water may lead to immediate seal failure or motor burnout due to liquid resistance.
