PPZ-series: fit for heavy duties
Wimmer radial piston pumps are hydraulic pumps with a constant volumetric output. These pumps can handle very high operating pressures of up to 700 bar. They are commonly used to supply hydraulic systems with pressure oil. Our PPZ high pressure pump is available with up to 3 pistons and amongst the smallest pumps in our range in terms of size. Yet this pump is perfectly suitable for heavy-duty jobs!
