Description

Radial piston pumps HRK BIERI radial piston pumps HRK are very light and compact designed high pressure radial piston devices with hollow shaft. This enables optimum space-saving installation with a direct mounted E-motor (without bell housing and coupling).
Optional adapted with integrated pump protection valve this pump series is unbeatable regarding multifunc-tionality and optimization of installation space. Operating pressure: - up to 700 bar Displacement volume: - 0,12 bis 0,34 cm³/U Speed Range: - 500 bis 3600 min⁻¹ Features - Advantages Compact design - Self-venting Hollow shaft - Very high volumetric efficiency on a wide speed range For direct assembly of motor without bell housing and coupling - Space-saving design Applications Machine tools Clamping device Power units (e.g. for presses, test benches) Pull-off fixtures Lifting systems Mobile power unit Small units For pulsing applications use BRK 701/702 Design With hollow shaft for direct assembly of motor without bell housing and coupling With 1 or 2 pumping elements (depending on size) Technical Data Hydraulic fluid - Mineral oil according to DIN 51524 (other fluids on request) Fluid temperature range - -20 up to 80°C Ambient temperature range - -30 up to 50°C Viscosity range - 12 to 220 mm²/s Operation pressure at suction port - -0,2 bar to 0,5 bar gauge pressure Max. operating pressure - 700 bar continuous pressure Filtration (recommendation) - According to NAS 1638 class 6 resp. ISO/DIN 4406 17/15/12 Weight - See technical data sheet Installation position - In tank (any)
