What kind of pump is this? Is it also called a plunger pump?

As shown in the figure, is this also a plunger pump? Can it handle high-viscosity materials? Like highly viscous polyvinyl alcohol? The viscosity is over 200,000; can it be drawn out using a bucket? I’ve used gear pumps before, but they all had one problem: they lacked suction power, so they could only push fluid out, but not draw it into the pump.
What kind of pump is this? I’ve never seen it before! Waiting for someone to answer!

Submersible pumps are not effective for pumping materials with high viscosity. You could try a screw pump or a gear pump; do they not have self-priming capability, so as to raise the liquid level of the material? Couldn’t you place the material tank at a higher position or upside down, and then use a large funnel tank or storage bin to hold the material temporarily?
To place the bucket on the ground and draw material out of it, there is no requirement regarding the lift height; it’s not even necessary to draw the material up to a height of two meters.
It is known in the industry as a barrel pump, or a pneumatic piston pump. Which manufacturer is it? Is a viscosity of 200,000 really feasible?
To avoid suspicion of advertising, the manufacturer’s name has been removed. Has anyone used this pump to draw up liquids of what viscosity?
This should be an axial flow centrifugal pump, with a maximum capacity of around 2000 CP
