Category: R4-Mini – fixed displacement

 Hydraulic pumps of type R4 “mini” are integral check valve controlled, self-priming radial piston pumps with fixed displacement. R4 mini pumps are designed for low flow, high pressure operation and long life.


  • Sizes 0.4 to 2.0
  • Radial piston pump with 3 pistons
  • Very compact build
  • Self-priming, valve-controlled
  • Long service life due to hydro-dynamically lubricated plain bearings
  • Optional combination with variable displacement vane pumps
