This sytem is mainly used for plan 53C pressurized dual seal, using the pistion principle to maintain a stable differential pressure between the spacer fluid pressure and the pump medium pressure.
The pressure source of the spacer fluid comes from the medium pressure and can achieve automatic pressurization. So when the medium pressure is flucting, the spacer fluid will be changed accordlingly.
This system requires the medium fluid should be clean and not affect piston movement.
The welding of pressure parts complies with JB/T4709 standard and it must be butt welded or double welded.
Working pressure: Max.6.3 Mpa
Working Temperature: -60~200℃
Easy to be detachable and clean.
