What type of pump is a multi-cylinder version designed for high pressure fog nozzles?

A multi-cylinder piston pump is indeed designed to generate high pressures, making it suitable for applications that require high pressure fog nozzles. This type of pump operates by using one or more cylinders to create a pushing action on a fluid, which allows for substantial pressure to be built up.

In firefighting, fog nozzles need high-pressure water to create a fine mist, helping to cool the environment, suppress fire, and provide protective barriers. The piston pump's ability to produce consistent high pressure makes it an ideal choice for this scenario.

While other pumps like centrifugal pumps are effective for moving large volumes of water, they are not typically designed to generate the high pressures needed for fog nozzle applications. Similarly, rotary gear pumps and rotary vane pumps are more suited for specific applications involving lower pressure or viscous fluids. Thus, the multi-cylinder piston pump stands out as the optimal solution for the demands of high-pressure fog nozzles in firefighting scenarios.
