Peristaltic pumps can have a wide range of flow rate capabilities, depending on factors such as the pump head size, tubing diameter, and pump speed.
Here are some typical flow rate ranges for peristaltic pump head:
- Small peristaltic pump heads (e.g. 0.5-3 mm tubing diameter): 0.1 to 400 mL/min
- Medium peristaltic pump heads (e.g. 3-8 mm tubing diameter): 1 to 2000 mL/min
- Large peristaltic pump heads (e.g. 8-14 mm tubing diameter): 10 to 10,000 mL/min
The flow rate range can also be influenced by:
- Pump rpm (revolutions per minute) - Higher rpm generally results in higher flow rates
- Tube material and durability - Softer tubing materials may have lower max flow rates
- Tube wall thickness - Thinner walls can allow for higher flow rates
- Back pressure in the system - Higher back pressure reduces the maximum achievable flow rate
It's important to consult the specifications provided by the peristaltic pump manufacturer to determine the appropriate flow rate range for a particular pump head and application. The pump's performance may need to be verified through testing as well.
