PW-series: gets the job done

The Wimmer radial piston pumps product line is a range of robust and durable hydraulic pumps intended for use in industrial applications. Its volumetric efficiency has led to it being the first choice for many machines with demanding flow and pressure control needs. Our PW series pumps are amongst the biggest pumps in our range in terms of size with available plungers up to 22 millimetres in diameter. With an operating pressure of up to 500 bar, these pumps will certainly get your job done!
