Can a check valve be installed on a micro-slurry pump?

I currently have a slurry pump with a capacity of 15 L/h; the slurry contains about 8% solid particles, with particle sizes less than 0.3 mm. Can a check valve be installed at the pump outlet to prevent backflow? I hope fellow experts can help answer this question!
What type of slurry pump are you? The design of each factory is different; for example, industrial hose pumps used for transporting slurries do not require any installation.
Reply to 2# yulancheng: Hello! I am using a hydraulic diaphragm pump to transfer material from a tank at atmospheric pressure to a reactor at 10 kilograms of pressure. During operation, it was observed that backflow occurred in the tank at atmospheric pressure when the pump stopped. I want to install a check valve, but I’m concerned about it getting clogged by solid particles.
Your solid particles aren’t very large; ordinary check valves tend to get clogged. You need to have a custom check valve with a pressure-activated mechanism. When the pressure is set to more than 10 KG, it shuts off automatically when the pump stops.
