Features
Page
- Pressureless start-up and circulation of the pump
- Provided for direct mounting to the SAE pressure port of the
pump
2, 3
- Low circulation pressure due to short distance
4
- Small compressive volume, hence smooth change-over to
4
pressureless circulation
5
- Fast pressure build-up
6 to 8
- 4 pressure adjustment elements, optional:
9 to
• Rotary knob
2
• Sleeve with hexagon and protective cap
• Lockable rotary knob with scale
3
• Rotary knob with scale
3, 4
- 5 pressure ratings, optional
