A miniature metering pump is needed
Thread Content
A miniature metering pump is required, with the following specifications: Voltage: 12V； Weight: Motor + pump head + driver ≤ 500g ； Flow rate: Can be precisely adjusted from 0 to 9 ml ； Operating environment temperature: -40~55°C (minimum low temperature of -20°C) ； Medium: water or saline; high reliability and stability are required. Gear pumps are preferred, and contact information for relevant agents would also be useful. Peristaltic pump tubing tends to stick together, and the hoses are prone to becoming brittle at high temperatures, making them unreliable.
Is the flow rate of 0–9 ml per minute?
