- Maximum operating pressure 350 bar
- Maximum flow 400 l/min
Features
- Zero-pressure start-up and circulation of the pump
- Intended for direct mounting onto the SAE pressure port of the pump
- Low circulation pressure due to short distance
- Low compression volume for soft switching to depressurized circulation
- Quick pressure build-up
- 4 adjustment types for pressure adjustment, optionally
- Rotary knob
- Sleeve with hexagon and protective cap
- Lockable rotary knob with scale
- Rotary knob with scale
- 5 pressure ratings, optional
- Low noise level due to direct flange mounting at the pump
