Pump tank extinguishers are used to apply which extinguishing agent?

Explanation:
Pump tank extinguishers use water as their extinguishing agent. These units store and discharge water, relying on its cooling effect to stop the combustion of ordinary combustibles like wood, paper, and cloth. Other agents—wet chemical (for commercial kitchens), dry chemical (a powder that interrupts chemical reactions), and carbon dioxide (good for electrical fires and enclosed spaces)—are not contained in pump-tank devices, which are designed specifically for delivering water to cool and suppress class A fires.
