| Some suggestion in my opinion: First, confirm your operating voltage, current, head, flow, and the size of inlet & outlet. In general, there is no flow when the head achieve the maximum head marked by factory. So if you require the pump is able to meet a certain height and also meet a certain flow, you should choose a higher maximum head than you need. Please consult us or refer to the performance curves. Second, confirm the shape requirements, such as the type of interface, the direction of inlet & outlet, etc. Third, confirm the working environment, such as the temperature, the medium, etc. Fourth, confirm the functional requirements, such as the time control, the motion control, the pressure control, the flow control, the speed control, etc. |
