Service Life & Maintenance Guidance

The gear motor and pump head must be replaced together after 120 operating hours. The charcoal pencil within the pump head wears at the same rate as the motor, so replacing the pump head alone is not possible — both components must be changed as a set.

Understanding your expected service interval:

• 30-minute analysis interval — approximately 2 years of service life
• 10-minute analysis interval — under 1 year of service life

We recommend scheduling replacement proactively based on your instrument's analysis interval to avoid unexpected downtime.

Compatibility

• Testomat® 808 (injection pump variant)
