1、 The flow requirement is relatively high (about 4-20 liters/minute), and the pressure requirement is not high (about 1-3 kilograms). It is mainly used for water circulation, water sampling, lifting, etc. It requires low noise, long service life, high self priming suction range, etc. BSP, CSP, and other series are optional;

2、 The flow requirement is not high (about 1~5 L/min), but the pressure is high (about 2~11 kg). It is mainly used for spray, pressurization, car washing, etc. It does not need to work under high pressure or heavy load for a long time, so ASP, HSP and other series can be selected;

3、 It is used for tea table water pumping, spray, etc. It is required that the volume should be as small as possible, the flow should be small, and the noise should be low (about 0.1~3 L/min). ASP and other series can be selected.

4、 High temperature working medium (0-100 ℃), requiring pumping or gas (may be mixed with water or air, idle or dry running situations), emphasizing performance such as volume, noise, and continuous use. The pump needs to idle and dry for a long time. If there is both water and gas in the pipeline, the WKA series of water and gas dual purpose pumps should be selected. The WKA series of micro water pumps is particularly suitable for occasions with water and air. It is used to pump water and air when encountering water and air. When there are the above applications, you can choose the WKA series.

5、 There is a high requirement for flow rate (over 20 liters/minute), but the medium contains a small amount of oil, solid particles, residues, etc.

There are three series of micro submersible pumps available: QZ (medium flow rate 35-45 liters/minute), QD (high flow rate 85-95 liters/minute), and QC (ultra large flow rate 135-145 liters/minute), as well as DC submersible pumps.
