EF918 Suitable Pump Heads and Tubing, Flow parameters
| Pump Drive | Pump Head | Speed | Tube Material | Tube | Max Flow(mL/min) |
| EF918 | KL40 | 265rpm | Silicone | 187# 186# | 20000mL/min |
Above flow parameters are obtained by using silicone tube to transfer pure water under normal temperature and pressure,in actually using it is effected by specific factors such as pressure, medium etc. Above for reference only.
