Which marine friend knows what type of high-pressure pump this is?

As shown in the figure, what type is the high-pressure foam pump? Ask about the working principle
A pneumatic piston metering pump uses an air source to drive the piston, thereby generating high-pressure, fine-flowed streams of fluid such as water. When these streams are injected into a container, they cause the fluid inside the container to form foam under the action of high-pressure water
Let me search on Baidu to find out what a pneumatic pulse pump is
Reliable, but from the pictures online, the appearance of pumps of this type varies quite a lot. Does this type of pump have directional valves, proportional valves, or something like that? The main problem now is that the pressure fluctuates greatly when the pump changes direction during operation, which affects production.
How can pressure fluctuations caused by reversal during operation of this pump be addressed to avoid affecting production?
