Top-level industrial pumps

PM-series: top-level industrial pumps

Wimmer radial piston pumps serve the industrial market for over four decades and are widely known for their robust and reliable design. Our PM series industrial pumps are certainly no exception. They are powerful and efficient and designed for operating pressures up to 700 bar. We are well aware that every task requires its own solution. That's why we offer you not only standard pumps, but we customize them as well.


  • 500 Bar / 700 Bar
  • 0,565 to 12,06 cm³/rev
  • High volumetric efficiency (up to 98%)
  • Wide speed range (100 > 3 000 rev/min)
  • Inexpensive design
  • 1 to 6 Pressure outputs possible (depending on n° pistons)
  • Low pulsation, low noise level
  • Self-priming and venting
  • Offshore versions available (Marine version)


  • Size 2 (solid concept)
  • Light weight solid version
  • High-strength aluminum body and piston-cover
  • Modular concept (easy to replace piston assembly)
