Hello Community
I have pressure problems in a 1290 Binary Pump (G4220A) because in most of the manteinances and repairs it had in the past the pump head assembling process was performed without the service kit. In this moment the pump cannot work with pressures above 600 bar. Even after assembling with the allignment tool and the correct torques, the pressure decreases with time with sporadic leak drops from inside the heads. In addition to this, the availability of the service kit is very limited.
Considering this I would like to know if it is possible to upgrade this pump with long-life pump heads which require no allignment tool.
Thank you for your help
Best Regards
