The piston pump uses a piston to generate high pressure, which is then transferred to the spraying system. This type of pump is ideal for applications where higher pressures and stable performance are required when spraying over longer distances. Piston pumps are suitable for larger gardens and more demanding spraying applications as they provide greater displacement and better control over pressure parameters. Piston pumps are popular for their robustness and high performance, although they can be more maintenance intensive than diaphragm pumps.
